Polaris RZR Factory Racing represents a major change in how production-based UTV racing is approached. Rather than supporting unrelated teams that independently modified recreational side-by-sides, Polaris created an integrated factory operation around purpose-built RZR Pro R race vehicles, dedicated personnel and direct engineering support.
The modern program debuted in 2023 and immediately won the SCORE Pro UTV Open championship. It followed with victories at the Baja 1000, Dakar Rally, King of the Hammers, Mint 400, Vegas to Reno and nearly every other major event it entered.
This history traces the development of the Polaris RZR Factory Racing team, the evolution from the Gen 1 RZR Pro R Factory to the Gen 2 and RZR Pro R Rally, the drivers behind its success and the connection between the race program and production RZR models.
Before the Modern Polaris RZR Factory Racing Team
Polaris had supported UTV racers long before creating its centralized Factory Racing operation. Independent teams built competition vehicles from production RZR platforms and raced them in SCORE, Best in the Desert, WORCS, short-course series and King of the Hammers.
Teams such as Jagged X, Holz Racing Products and Walker Evans Racing helped establish the RZR as a legitimate competition vehicle. Brandon Schueler, Mitch Guthrie Sr., Mitch Guthrie Jr., RJ Anderson, Wayne Matlock, Branden Sims and many other racers accumulated victories in desert racing, short-course competition and King of the Hammers. Polaris RZR drivers were particularly dominant during the formative years documented in our history of the King of the Hammers UTV race.
Polaris commonly referred to these supported racers collectively as RZR Factory Racing. However, the drivers generally operated through independent teams with their own vehicles, mechanics, sponsors and development programs.
That approach produced championships and helped drive the rapid development of the RZR platform. It also meant lessons learned by one team were not always incorporated into a single standardized race vehicle or shared through a centralized engineering process.
The introduction of the production Polaris RZR Pro R gave Polaris an opportunity to take a fundamentally different approach.
Polaris Forms a Complete Factory Racing Team
In 2023, Polaris established a dedicated Factory Racing organization managed in partnership with SCI Motorsports. Instead of supplying production vehicles and parts to independent teams, Polaris developed a purpose-built race UTV and created a permanent operation responsible for preparation, engineering, logistics and competition.
The initial driver lineup included Brock Heger, Cayden MacCachren and Austin Weiland. Craig Scanlon competed through the SCI operation and played an important role in establishing and managing the program. Johnny Nelson served as crew chief, overseeing vehicle preparation and technical development.
The permanent race shop initially operated with approximately 10 full-time employees responsible for vehicle preparation, parts, logistics and race planning. That number expanded dramatically at major events. General Manager Ryan Thomas said the complete operation could grow to approximately 75 or 80 people at the racecourse, including seven to 10 Polaris personnel supporting the program from Minnesota.
The scale of that operation helps distinguish the modern Factory team from Polaris’ earlier network of sponsored and supported racers. The race vehicles may receive most of the attention, but the program also depends on engineers, mechanics, parts specialists, logistics personnel, chase crews and communications teams working from a coordinated plan.
Gen 1 RZR Pro R Factory: Polaris Builds a Purpose-Built Race UTV
The first-generation RZR Pro R Factory was developed specifically for long-distance desert racing. It was not a showroom Pro R fitted with a roll cage and safety equipment.
The race vehicle used the production RZR Pro R as its engineering foundation. Its naturally aspirated 2.0-liter ProStar Fury four-cylinder engine was the same core engine used in the production machine, while many drivetrain and suspension components also carried over from the recreational Pro R.
Polaris then surrounded those components with a race-specific chassis, cockpit, fuel system, cooling package, electronics and suspension configuration designed for sustained competition.
Gen 1 RZR Pro R Factory Highlights
- A production-based 2.0-liter ProStar Fury engine installed within a race-specific cooling, fuel and electronics package
- Purpose-built chromoly and high-strength-steel chassis
- Race-spec MaxLink suspension
- FOX Live Valve X2 shocks with DYNAMIX DV control
- MoTeC engine management, power distribution and data logging
- Large-capacity fuel cell for long-distance desert racing
- Alcon braking system with adjustable in-cab brake bias
- 35-inch BFGoodrich race tires
- Integrated spare tires, tools and competition equipment
The Factory vehicle retained enough production RZR DNA to remain relevant to the Pro R platform, but every system was evaluated around racing. Strength, cooling, serviceability, driver protection, fuel range and surviving hundreds of miles at speed took priority over recreational comfort.
For a detailed comparison, see our breakdown of the Polaris RZR Pro R versus the RZR Pro R Factory.
The First Race and an Undefeated 2023 SCORE Season
The new Factory operation debuted at the 2023 SCORE San Felipe 250. Craig Scanlon and Max Eddy Jr. won the Pro UTV Open class during the program’s first race, immediately validating the new vehicle and team structure.
Brock Heger followed with an overall UTV victory at the Baja 500. The result demonstrated that the Factory program could do more than win its individual SCORE class; it could compete for the fastest UTV time across the entire field.
Heger also won the Baja 400, extending the team’s undefeated start and putting himself in position to claim the SCORE Pro UTV Open championship.
At the Baja 1000, Cayden MacCachren delivered the program’s first victory in the race. The 2023 event ran from La Paz to Ensenada, requiring the team to cover the full Baja peninsula while coordinating drivers, chase vehicles, fuel stops and remote service locations.
MacCachren’s victory completed an undefeated inaugural SCORE season for the modern Factory Racing team. Brock Heger secured the Pro UTV Open championship, giving Polaris a race win and season title during the program’s first year.
Polaris Takes the RZR Pro R Factory to Dakar
While the North American Factory team concentrated on SCORE competition, Polaris expanded the platform into international rally raid through a partnership with Sébastien Loeb Racing.
Dakar presented a very different challenge from Baja. Instead of one continuous point-to-point race, competitors faced consecutive stages, navigation requirements, service limitations and nearly two weeks of competition in Saudi Arabia.
Xavier de Soultrait and navigator Martin Bonnet won the 2024 Dakar Rally SSV category in a RZR Pro R Factory. Their margin over the second-place team was only a few minutes after thousands of racing miles.
The victory proved that the Pro R Factory architecture could succeed beyond SCORE desert racing. It also gave Polaris its first Dakar SSV championship and established an international side of the Factory Racing program.
Gen 2 RZR Pro R Factory Debuts in 2024
Despite the success of the first vehicle, Polaris introduced a substantially revised Gen 2 RZR Pro R Factory for the 2024 SCORE season.
The second-generation vehicle retained the naturally aspirated ProStar Fury engine and recognizable Pro R architecture while improving weight distribution, ergonomics, serviceability, cooling and suspension performance.
The team moved the driver and co-driver positions closer together, revised the bodywork and reorganized systems to make the vehicle easier to inspect and service. Development feedback from the entire 2023 SCORE season influenced the redesign.
The decision to introduce Gen 2 after only one season demonstrated one of the advantages of the centralized Factory structure. Drivers, mechanics and Polaris engineers could identify issues, compare data and incorporate changes into every primary race vehicle.
An Undefeated 2024 SCORE Season
The Gen 2 RZR Pro R Factory won its debut at the 2024 San Felipe 250 with Cayden MacCachren driving. Brock Heger finished second, giving the team a 1-2 overall UTV result.
MacCachren followed the San Felipe victory by winning the 2024 Baja 500 in the Gen 2 RZR Pro R Factory. He later added another overall victory at the Baja 400.
Brock Heger completed the season with his first Baja 1000 victory. Rather than divide the course among multiple drivers, Heger drove the entire race himself. He continued through darkness, rain, snow and cold conditions without leaving the vehicle, finished approximately 45 minutes ahead of the next UTV and placed seventh among all four-wheeled vehicles.
Heger later described his approach to the solo effort: “I figured the faster I went, the sooner I can get back.” After finishing, he packed a bag, drove to Los Angeles International Airport and immediately departed for the Dakar Rally.
The 2024 Baja 1000 victory also secured Heger’s second consecutive SCORE Pro UTV Open championship.
The result completed a second undefeated SCORE season for the modern Factory program. Through its first two years, Polaris RZR Factory Racing had won its class at every SCORE race it entered.
Max Eddy Jr. Joins the Factory Driver Lineup
Max Eddy Jr. officially joined Polaris Factory Racing as its fourth driver for the 2024 season.
Eddy was already deeply involved with the operation after serving as Craig Scanlon’s co-driver during the inaugural SCORE campaign. His racing background included five Baja 500 motorcycle victories, five Baja 1000 motorcycle wins and extensive experience navigating for leading Trophy Truck teams.
Eddy finished second overall behind Heger at the 2024 King of the Hammers Desert Challenge during his first race as an official Factory driver.
His versatility allowed him to race a Factory RZR in Baja, provide development feedback and use his navigation experience during the team’s Dakar program.
Brock Heger and Max Eddy Win the 2025 Dakar Rally
Brock Heger entered the 2025 Dakar Rally as a rookie, with Max Eddy Jr. navigating.
Polaris and Sébastien Loeb Racing returned with the championship-proven Gen 2 platform. Heger and Eddy took control early, led the 39-vehicle SSV field for 10 consecutive stages and won the category by more than two hours.
The 2025 Dakar victory by Brock Heger and Max Eddy Jr. gave Polaris its second consecutive Dakar SSV championship.
It also demonstrated two very different paths to victory. De Soultrait and Bonnet survived a close 2024 contest decided by minutes. Heger and Eddy controlled the 2025 rally and won by hours.
King of the Hammers Tests the Factory Platform in the Rocks
King of the Hammers presented two distinctly different competitions for the Factory team:
- The high-speed King of the Hammers Desert Challenge
- The technical UTV Hammers Championship
Heger won the 2025 King of the Hammers Desert Challenge shortly after returning from Dakar.
He then entered the technical rock race in a specially configured RZR Pro R Factory. The UTV Hammers Championship combines fast desert terrain with extreme rock trails where gearing, visibility, turning radius, tire placement and low-speed suspension control become critical.
Heger was the only driver to finish in under four hours and crossed the line 26 minutes ahead of the next physical competitor. His 2025 UTV Hammers Championship victory completed an extraordinary stretch that included the Baja 1000, Dakar Rally and both King of the Hammers UTV races.
The achievement is also an important chapter in the broader history of the King of the Hammers UTV race.
The Polaris film UNPRECEDENTED follows Heger’s extraordinary run through the Baja 1000, Dakar Rally and King of the Hammers—three events requiring distinctly different driving skills and vehicle preparation.
Brock Heger Completes an Off-Road Racing Triple Crown
Polaris’ UNPRECEDENTED film describes the Dakar Rally, Baja 1000 and King of the Hammers as an unofficial “triple crown of off-road racing.” Each event tests a different combination of driver skill and vehicle capability.
- Baja 1000: Sustained desert speed, nighttime driving, changing weather and nearly 1,000 miles of continuous competition
- Dakar Rally: Navigation, vehicle preservation and repeated long-distance stages across nearly two weeks
- King of the Hammers: High-speed desert racing combined with extreme rock crawling and technical vehicle placement
Winning all three within a period of only a few months required Heger to adapt from solo Baja endurance racing to international rally raid and then technical rock racing. It also demonstrated the unusual versatility of the RZR Pro R Factory platform.
Heger explained that adaptability is part of what attracts him to off-road racing: “I enjoy driving versatile things and being able to adapt to different scenarios, different courses.”
Why Gen 1 Remained Important for Rock Racing
Gen 2 replaced Gen 1 as the primary SCORE desert-racing platform, but the original vehicle did not immediately become obsolete.
The team continued using modified Gen 1 Factory vehicles for technical rock racing. That configuration provided a proven starting point for the specialized demands of the UTV Hammers Championship.
Polaris Factory Racing again won the King of the Hammers Desert Challenge in 2026, continuing the program’s success at Johnson Valley.
RZR Factory Racing Wins the Mint 400
RZR Factory Racing made its official Mint 400 debut in March 2025.
Heger won the UTV Pro Open class, took the UTV overall victory and finished ahead of the entire four-wheeled Limited race field. Polaris-powered vehicles swept the top 10 positions in the class.
The 2025 Mint 400 victory added another major event to a growing list that already included Baja, Dakar and King of the Hammers.
Heger returned in 2026 and won again. He completed the race in 6:57:56, becoming the first limited-class side-by-side racer to finish the event in under seven hours. Mitch Guthrie Jr. placed second overall in another RZR Pro R Factory.
The record-setting 2026 Mint 400 victory gave Heger and Polaris back-to-back wins at the historic Nevada race.
The Undefeated 2025 Season
The 2025 campaign became the clearest evidence of the Factory program’s competitive dominance.
RZR Factory Racing or a designated Factory-platform entry claimed the UTV overall victory at every major event on the program’s schedule:
| 2025 event | Winning driver or team |
|---|---|
| Dakar Rally | Brock Heger and Max Eddy Jr. |
| King of the Hammers Desert Challenge | Brock Heger |
| UTV Hammers Championship | Brock Heger |
| Mint 400 | Brock Heger |
| SCORE San Felipe 250 | Brock Heger |
| SCORE Baja 500 | Brock Heger |
| SCORE Baja 400 | Brock Heger |
| Vegas to Reno | Mitch Guthrie Jr. |
| SCORE Baja 1000 | Cayden MacCachren and Ethan Groom |
The 2025 Baja 500 produced an all-Factory 1-2-3 overall podium, led by Heger ahead of MacCachren and the Ethan Groom/Justin Morgan entry.
Heger led another Factory podium sweep at the 2025 Baja 400.
At Vegas to Reno, Mitch Guthrie Jr. won the UTV division in a RZR Pro R Factory and finished second among all four-wheeled vehicles. The corrected-time margin after hundreds of miles was only nine seconds.
MacCachren and Ethan Groom completed the perfect season with an overall UTV victory at the Baja 1000. Max Eddy Jr. finished third, while Polaris-supported racer Branden Sims placed second.
The complete undefeated 2025 Polaris RZR Factory Racing season was remarkable because the victories were not confined to one series or type of terrain. The underlying platform won in rally raid, Baja endurance races, Nevada desert races and the rocks of Johnson Valley.
From Factory-Only Vehicle to Customer Race UTV
For its first two seasons, the RZR Pro R Factory was restricted to the Polaris team and selected racing partners.
Polaris subsequently made a competition-ready version available to qualified customers for the 2025 racing season. Initial production was limited to 30 vehicles, with SCI Motorsports handling sales and technical support.
The customer Polaris RZR Pro R Factory race UTV could be ordered with a 225-horsepower engine or an optional 255-horsepower high-output package.
| Specification | Customer RZR Pro R Factory |
|---|---|
| Engine | Production-based 2.0-liter ProStar Fury four-cylinder |
| Power | 225 hp standard or optional 255 hp |
| Chassis | 4130 chromoly and high-strength steel |
| Estimated dry weight | 2,510 pounds |
| Suspension | Race-spec MaxLink |
| Shocks | FOX Live Valve X2 with DYNAMIX DV |
| Brakes | Alcon with adjustable in-cab brake bias |
| Tires | 35-inch BFGoodrich KR2 |
| Fuel capacity | Approximately 34.3 gallons |
| Electronics | MoTeC ECU, power distribution and data logging |
| Original starting price | $139,999 |
The customer program expanded the Factory platform beyond a small number of Polaris-owned entries. Established private teams could begin with a complete OEM-developed race vehicle rather than converting a production Pro R and engineering every major system themselves.
The 2026 Baja 500 Demonstrates the Platform’s Reach
The influence of the customer program became especially clear during the 2026 SCORE Baja 500.
Branden Sims took the overall UTV victory, followed by Wayne Matlock and Factory driver Ethan Groom. Mitch Guthrie Jr., Dallas Gonzalez and Joe Terrana completed the top six.
All six were driving RZR Pro R Factory race vehicles. Polaris racers occupied the first nine overall UTV finishing positions.
The 2026 Baja 500 sweep was broader than a conventional Factory-team victory. It demonstrated that the race platform could produce winning results in the hands of core team drivers, customer teams and experienced Polaris-supported racers.
RZR Pro R Rally and a Third Consecutive Dakar Victory
For the 2026 Dakar Rally, Polaris and LOEB FrayMédia Motorsport expanded to a five-driver lineup and introduced another purpose-built race platform.
The proven RZR Pro R Factory remained available for the T4 category, while the new RZR Pro R Rally was developed for changing FIA regulations and the new SSV1 class.
The expanded 2026 Dakar program included previous winners Brock Heger and Xavier de Soultrait along with additional international entries.
The RZR Pro R Rally retained important production Pro R components, including the engine, driveline and suspension architecture. It added an FIA-homologated structure, revised bodywork, MoTeC electronics, competition cooling and systems developed around the new regulations.
Heger and Eddy led nearly the entire 13-stage rally, won six stages including the Prologue and finished more than an hour ahead of the next competitor. De Soultrait placed third.
The 2026 Dakar victory gave Polaris three consecutive SSV wins:
- 2024: Xavier de Soultrait and Martin Bonnet
- 2025: Brock Heger and Max Eddy Jr.
- 2026: Brock Heger and Max Eddy Jr.
Polaris RZR Factory Racing Drivers
Brock Heger
Brock Heger has become the driver most closely associated with the modern RZR Factory Racing program. His accomplishments include consecutive SCORE championships, multiple Baja 500 and Baja 400 victories, the Baja 1000, two Dakar wins, King of the Hammers and back-to-back Mint 400 victories.
His ability to move between Baja endurance racing, navigation-intensive rally raid, technical rock crawling and high-speed Nevada desert racing has been central to the program’s success. The Polaris film UNPRECEDENTED argues that the full significance of Heger’s driving becomes apparent after riding with him and watching how calmly he responds when conditions or the vehicle create a problem.
Heger’s own outlook is more direct: “For me, I’m happy being behind the wheel no matter what race it’s at. I’m just going to put my best foot forward and get to the finish line.”
Cayden MacCachren
Cayden MacCachren delivered the program’s first Baja 1000 victory in 2023. He followed with San Felipe 250, Baja 500 and Baja 400 wins in 2024 before returning to the top of the Baja 1000 podium with Ethan Groom in 2025.
His results gave the team the depth required to keep winning when mechanical problems or race circumstances affected other entries.
Max Eddy Jr.
Max Eddy Jr. progressed from co-driver to Factory driver and Dakar-winning navigator. His background in motorcycle racing, driving, navigation and Baja competition made him one of the team’s most versatile members.
Austin Weiland
Austin Weiland was one of the three original Factory drivers. Although his tenure was shorter than those of Heger and MacCachren, he helped put the new Gen 1 vehicle through its first season of competition and development.
Ethan Groom
Ethan Groom initially contributed as Heger’s co-driver before moving into a larger driving role. He shared the 2025 Baja 1000 victory with MacCachren and earned an overall podium at the 2026 Baja 500.
Groom and Justin Morgan’s competition for the available Factory seat became a significant storyline during the 2025 Baja 500 program.
Craig Scanlon
Craig Scanlon helped organize and manage the modern Factory program through SCI while also competing. His Pro UTV Open class victory at the 2023 San Felipe 250 gave the new operation a win at its first event.
Xavier de Soultrait
Xavier de Soultrait established the program internationally by winning the 2024 Dakar Rally with navigator Martin Bonnet. His rally-raid experience complemented the team’s North American desert-racing expertise.
Joe Terrana
Joe Terrana joined the core 2026 SCORE lineup and finished sixth overall at the Baja 500 with Rodrigo Ampudia. The Terrana/Ampudia entry also brought one of Baja racing’s most recognizable liveries into the Factory program.
Customer and Partner Drivers
Not every successful RZR Pro R Factory racer is a member of the core Factory team. Mitch Guthrie Jr., Branden Sims, Wayne Matlock and other established racers have competed through customer or partner programs.
The distinction matters because the platform’s growing record now reflects both the centralized Polaris operation and the expansion of the customer race-car program.
2026 Factory Lineup and the Polaris SCORE Challenge
Polaris entered the second half of the 2026 SCORE season with four primary Factory drivers:
- Brock Heger
- Cayden MacCachren
- Ethan Groom
- Joe Terrana
Following the platform’s sweep at the Baja 500, Polaris announced a $50,000 challenge for the 2026 Baja 400. A non-Polaris racer can earn the prize by beating all four Factory entries and winning the UTV overall.
The Polaris SCORE Baja 400 Challenge demonstrates how confident the company has become in both its team and race vehicle.
Where the 2027 RZR Pro R Boost Fits Into Racing
The introduction of the 2027 Polaris RZR Pro R Boost creates a new competition path alongside the naturally aspirated RZR Pro R Factory. With a turbocharged 2.0-liter four-cylinder engine producing 275 horsepower, the production Pro R Boost falls outside the performance envelope of existing naturally aspirated Pro R and 1.0-liter turbo classes.
Polaris has worked with major off-road racing organizations to establish eligibility before customers begin converting Pro R Boost vehicles into race UTVs. The new model will compete in dedicated categories rather than racing directly against the current naturally aspirated Pro R or existing 1.0-liter turbocharged UTVs.
| Racing Organization | RZR Pro R Boost Class |
|---|---|
| SCORE International | Pro UTV Ultimate |
| King of the Hammers | B2 Desert |
| American Off-Road Championship | Dedicated class; official name to be announced |
This does not mean the Pro R Boost has replaced the RZR Pro R Factory. Polaris says the naturally aspirated Factory platform remains fully supported and will continue to be raced and developed by factory and customer teams.
Polaris has also not announced a Factory Racing Pro R Boost race vehicle or competition debut. For now, the Pro R Boost expands the company’s racing portfolio by giving racers a separate path from the showroom to dedicated competition classes, while the proven RZR Pro R Factory remains the foundation of the current factory program.
How Factory Racing Influenced Production RZR Models
The Factory race vehicle is not a production model, but the relationship between the two platforms works in both directions.
The connection goes beyond sharing a basic engine design. During a Factory shop tour, Crew Chief Johnny Nelson identified the engine as the same core engine used in the production RZR Pro R. Operations Director Adam Arsenal also said the team installs production Polaris clutches without modifying them. Stock thermostats, spark plugs, lubricants and numerous other cataloged Polaris parts are used throughout the Factory vehicles.
That does not make the RZR Pro R Factory a production UTV. Its chassis, fuel system, cooling, electronics, cockpit and numerous competition systems are purpose-built for racing. However, retaining key production components allows Polaris to evaluate those parts under sustained loads and temperatures far beyond typical recreational use.
Competition allows Polaris to test systems under loads, speeds and operating temperatures that would be difficult to duplicate during recreational use.
The Factory program has also tested emerging chassis technology. One example is the use of SDi active sway-bar links during SCORE competition. Related SDi technology later appeared on the 2026 Polaris RZR Pro R Ultra Edition.
That connection should not be interpreted as proof that the production system was transferred directly from the race vehicle, but Factory Racing provided a demanding environment in which active sway-bar technology could be evaluated. The race application is examined in From Baja to the Trail: How SDi Active Sway Bar Links Are Tested in Racing.
Polaris also released the limited-production 2025 RZR Pro R Race Replica. It combined a production Pro R Ultimate with Factory-inspired Podium Purple graphics, Method wheels, BFGoodrich tires, RIGID lighting and other appearance and equipment upgrades.
The Race Replica was not a recreational version of the dedicated Factory car, but it gave customers a direct visual connection to the championship-winning program.

Why Polaris RZR Factory Racing Has Been So Successful
No single component or driver explains the Factory program’s record.
The naturally aspirated ProStar Fury engine gave Polaris a powerful foundation with predictable power delivery. The specialized Factory chassis provided room for long-travel suspension, substantial fuel capacity, cooling equipment and spare parts. DYNAMIX-controlled FOX suspension allowed the vehicles to maintain speed through changing terrain.
The organizational structure has been just as important. Direct communication between drivers, mechanics and Polaris engineers allowed problems discovered during a race to influence the next version of the vehicle.
This tour of the Polaris Factory Racing shop provides a closer look at the people, equipment, race preparation and data analysis supporting the RZR Pro R Factory program.
Race Preparation, Data Collection and Component Life Cycles
A look inside the Polaris Factory Racing shop shows how methodically that feedback loop operates. After each race, the vehicles are washed, inspected, aligned and substantially disassembled. The team removes the drivetrain and other wearable components while generally leaving the wiring and plumbing installed unless those systems require specific attention.
Components are tracked through predetermined service lives rather than being replaced only after a visible failure. Crew Chief Johnny Nelson explained that many drivetrain and suspension components were managed around a life cycle of approximately 1,500 racing miles. Mileage records, post-race alignment measurements and physical inspections help the team decide whether a part can remain in service.
The vehicles also collect information during competition. MoTeC electronics record extensive vehicle data, while approximately 15 to 20 temperature indicators positioned around each car help the team identify peak temperatures at areas such as CV joints. After a race, drivetrain-fluid samples are analyzed for signs of bearing wear, water contamination and other internal problems.
“We have great components that go the distance,” Nelson said, “but we’re always looking for those things.” A four-wheel alignment after every race can reveal a suspension component that was slightly bent during an unusually severe impact even when the damage is not otherwise obvious.
Used parts are retained so Polaris and its technical partners can inspect abnormal wear or identify potential improvements. FOX services the race shocks, while fluid analysis can reveal internal component conditions that would otherwise remain hidden. This process gives the Factory program value beyond individual race results: competition produces data that can inform future race development and, when applicable, production components and fluids.
Supporting Multiple Factory Cars in Baja
Vehicle preparation is only part of the challenge. During a Baja race, Factory personnel scout pit locations based on fuel range, course access and the ability to position heavy chase trucks in remote areas. Each truck functions as a mobile version of the race shop, carrying tools and replacement components ranging from drive belts to differentials.
With multiple Factory entries spread across the course, the team cannot rely entirely on one or two trucks leapfrogging ahead of a single race vehicle. Support stations must remain available at predetermined locations so every driver can count on parts, fuel and assistance. Depending on the course, some form of support may be positioned approximately every 25 to 50 miles.
VHF radios, satellite communications, live vehicle tracking and mobile Starlink connectivity allow the team to coordinate its race vehicles, chase trucks and pit crews. Each Factory race vehicle was also equipped with Starlink by the time of the shop tour.
“Everything that’s done here is done with the mindset that we have to be prepared for the unexpected.”
— Ryan Thomas, General Manager, Polaris Factory Racing
That preparation sometimes takes place under severe time pressure. Thomas said the shop may have only 10 to 14 days to tear down the Factory vehicles, inspect and replace components, and prepare them for the next race. The program tracks component life rather than treating its resources as unlimited, balancing reliability with the need to use each part efficiently.
That feedback loop produced the Gen 2 chassis after only one season and later supported the customer race-car program and development of the RZR Pro R Rally.
The team also developed exceptional depth. Heger produced the largest number of victories, but MacCachren, Scanlon, de Soultrait, Groom and other drivers were able to win under different conditions. Customer and partner racers then demonstrated that the platform could remain competitive beyond the core Factory operation.
The result is more than one dominant driver or a single exceptional season. Polaris created a repeatable racing system built around engineering, preparation, driver talent and a vehicle adaptable to several forms of off-road competition.
The Continuing History of Polaris RZR Factory Racing
Polaris RZR Factory Racing was created to show what could happen when an OEM approached UTV competition as a complete professional motorsports program.
Its first several seasons produced an extraordinary record: consecutive SCORE championships, an undefeated 2025 campaign, victories at King of the Hammers, the Mint 400 and Vegas to Reno, and three consecutive Dakar SSV wins.
The RZR Pro R Factory also changed the relationship between production UTVs and professional race vehicles. It began with recognizable production Pro R components, evolved into a highly specialized Factory platform and eventually became a turnkey race UTV available to private teams.
Heger has also identified an even larger target: using the comparatively affordable Polaris race platform to challenge Trophy Trucks for an overall SCORE victory. His Baja 1000 performance near the front of the entire four-wheel field showed why that goal is no longer entirely theoretical.
The next chapter will be shaped by customer racers, the RZR Pro R Rally, the new competition pathway for the production RZR Pro R Boost, changing international regulations and whatever new technology Polaris chooses to test under competition conditions.
The program’s place in the history of the RZR is already secure. Polaris did not merely sponsor another collection of race teams. It created an integrated factory operation, developed purpose-built race UTVs and immediately began winning many of the biggest events in off-road racing.
