The 2016 Polaris RZR XP 4 1000 High Lifter Edition brought Polaris and High Lifter’s factory mud package to a four-seat sport UTV for the first time. Built for riders who wanted to take family or friends into deep mud without starting with an aftermarket conversion, it combined a 110-horsepower engine with mud-specific gearing, raised air intakes, aggressive tires and high-clearance suspension components.
The four-seat model followed the original two-seat RZR XP 1000 High Lifter Edition introduced for 2015. Its arrival represented an important expansion of the factory mud-UTV category and another milestone in the broader history of Polaris High Lifter and Mud Edition UTVs.

Four Seats for Serious Mud Riding
Polaris introduced the first RZR XP 1000 High Lifter Edition as a two-seat model, but mud riding is often a social activity. The RZR XP 4 version extended the same basic formula to four occupants while retaining the long-wheelbase platform and performance character of the Polaris RZR family.
The result was more than a conventional RZR XP 4 fitted with large mud tires. Polaris and High Lifter coordinated the engine, cooling system, gearing, suspension and intake routing around the demands of deep mud and standing water.
110-Horsepower ProStar Engine and Mud-Specific Gearing
Power came from the 999cc ProStar 1000 H.O. twin-cylinder engine, rated at 110 horsepower. The additional output was useful, but gearing was just as important when turning heavy, aggressively lugged tires through thick mud.
Polaris equipped the RZR XP 4 High Lifter Edition with reduced gearing to improve torque delivery at the wheels. A larger reverse chain helped the transmission withstand the substantial loads created when a driver needed to back the machine out of a deep hole.
Mud-specific cooling provisions helped the powertrain cope with conditions that could restrict airflow or cover parts of the vehicle with heavy debris. Together, these changes made the powertrain better suited to sustained low-speed work than a standard sport UTV fitted with oversized tires after purchase.
Raised Intakes for Deep Mud and Water
Keeping water and debris out of the engine and clutch system is critical in a purpose-built mud UTV. Polaris mounted the engine intake, clutch intake and clutch outlet high on the RZR XP 4 High Lifter Edition.
Vent lines were integrated into the cab frame, helping position them away from mud and debris. This factory routing created a cleaner and more coordinated installation than the collection of separate snorkel extensions commonly added to standard machines.
Raised intakes did not make the RZR invulnerable to water. Water depth, current, speed and unexpected holes still required careful judgment from the driver. However, the elevated system gave the High Lifter Edition substantially more capability in wet terrain than a standard RZR XP 4.
15 Inches of Ground Clearance
High-clearance lower A-arms and rear radius rods helped the RZR XP 4 High Lifter Edition deliver 15 inches of ground clearance. Their arched profiles also created more space around deep ruts and obstacles hidden below the surface.
Polaris installed stiffer springs to help the vehicle maintain its ride height as mud accumulated on the chassis and suspension. That detail addressed a problem specific to mud riding: a machine can gain considerable weight during a ride as wet material builds up underneath it.
The suspension changes also helped compensate for four occupants and the additional weight of the High Lifter equipment. Although the added ride height and aggressive tires created compromises outside the mud, the complete package was engineered around its intended environment.
29.5-Inch High Lifter Outlaw 2 Tires
The most visually obvious part of the package was its set of 29.5-inch High Lifter Outlaw 2 tires. Their tall, widely spaced tread lugs were designed to dig through soft terrain while clearing mud as the tires rotated.
The Outlaw 2 tires worked with the reduced gearing rather than serving as an isolated upgrade. That integration was one of the High Lifter Edition’s main advantages over installing large mud tires on a standard RZR without modifying the gearing or driveline to match.
Factory Winch and Mud-Friendly Cab
A 4,500-pound winch with synthetic rope was standard equipment. Polaris placed the controls in the dash, allowing the driver to operate the winch without adding a separate aftermarket switch installation.
The RZR XP 4 also received factory half doors designed to help keep mud away from the occupants. Sealed contact areas around the rocker panels and front fenders reduced the amount of debris entering the cabin, while Dryseat technology helped the seating surfaces remain more comfortable in wet conditions.
Removable floor drains simplified cleanup after a day in the mud. Electronic power steering reduced steering effort with the large tires, and a standard rearview mirror helped the driver monitor rear-seat passengers and other vehicles on the trail.
Why the Four-Seat High Lifter Edition Mattered
The RZR XP 4 1000 High Lifter Edition showed that a specialized factory mud UTV did not need to be limited to two occupants. It delivered the passenger capacity of a four-seat recreational machine while retaining the raised intakes, gearing, clearance, tires and recovery equipment expected from a serious mud package.
Its importance was not based on any one component. Mud riders had already been adding snorkels, tires, suspension parts and winches to UTVs for years. What Polaris and High Lifter offered was a coordinated package in which those parts were developed to work together from the factory.
That same philosophy was apparent when we later visited the High Lifter Proving Grounds with Polaris RZR and RANGER High Lifter Editions. The experience demonstrated how much specialized engineering goes into making a mud-focused UTV work as a complete vehicle.
From the RZR High Lifter Edition to the RANGER Mud Edition
The High Lifter Edition name eventually disappeared from the Polaris side-by-side lineup, but the factory mud concept survived. Polaris returned to the category with the 2027 Polaris RANGER XP 1000 Mud Edition, offered in both three-seat and six-seat configurations.
The newer RANGER uses different tires and carries Polaris Mud Edition branding rather than the High Lifter name, but its raised intakes, arched suspension arms, underbody protection and high-mounted winch follow the same fundamental formula.

Final Thoughts
With 110 horsepower, four seats, 15 inches of ground clearance and a carefully integrated collection of mud-specific equipment, the 2016 Polaris RZR XP 4 1000 High Lifter Edition was one of the most specialized four-seat sport UTVs of its era.
It allowed a group of riders to leave the dealership with a properly developed mud machine instead of building one part by part. More importantly, it helped prove that factory mud editions could expand beyond a niche two-seat model and become a distinct part of the side-by-side market.
