2008 Polaris RZR 800 Project Build

2008 Polaris RANGER RZR 800

The original 2008 Polaris Ranger RZR 800 changed the direction of the side-by-side market. Its compact 50-inch width, low seating position and performance-oriented design established the formula that would eventually grow into the modern Polaris RZR lineup.

We purchased one of the early RZR 800s and immediately began turning it into a more capable trail, desert and dune machine. The project included long-travel suspension, safety equipment, performance upgrades, communications gear, protection and comfort improvements.

This page serves as the central index for the complete build. It preserves the individual product reviews and shows how UTVGuide.net modified the original RZR during the early years of the sport UTV aftermarket.

Safety and Driver Equipment

Safety was one of the first areas we addressed. The stock machine received upgraded seating and restraints, a replacement roll cage, mirrors, additional lighting and other equipment suited to group rides and nighttime dune use.

Safety equipment used

  • Suspension seats: Premier Racing Products (PRP)
  • Harnesses and restraints: PRP and Hart’s Rhino Motorsports
  • Rearview and side mirrors: Machine Trix Unlimited
  • Roll cage: Hot Ride
  • HID lighting: Baja Designs
  • Fuse and relay block: Autotrend
  • Front bumper: Lonestar Racing
  • Fire-extinguisher mount: Motorsports2

Long-Travel Suspension, Wheels and Tires

The suspension was one of the most important parts of the build. A Fireball Racing long-travel system increased wheel travel and track width, while supporting chassis components helped prepare the early RZR for harder trail, desert and dune use.

The complete installation and driving impressions are covered in our Fireball Racing RZR long-travel review, which also appeared in the March 2008 issue of Side x Side Action Magazine.

Suspension and chassis components

  • Long-travel suspension: Fireball Racing
  • Shocks and springs: Bilstein and Eibach
  • Axles: Fireball Racing
  • Tie rods: Fireball Racing
  • Rear frame gusset: ATR
  • Chassis legs: ATR
  • Billet hubs: Fireball Racing
  • Dune wheels and tires: Fullerton Sand Sports

RZR 800 Performance Upgrades

The first stage of engine work focused on complementary bolt-on upgrades. The combination included an improved intake, dual exhaust, fuel controller and modified airbox cover.

Performance components

  • Air intake: Unique Metal Products
  • Dual exhaust: Muzzys
  • Fuel controller: Dynojet Power Commander III
  • Airbox cover: EHS Racing

Communications and Navigation

Because the RZR was used on long desert rides with larger groups, we added an in-vehicle radio and intercom system from Rugged Radios. This allowed the occupants to communicate inside the vehicle while also maintaining radio contact with the rest of the group.

Bodywork, Protection and Accessories

  • Replacement bodywork: Fullbore Innovations
  • Spring-loaded gas pedal: Lonestar Racing
  • Brake pedal: Lonestar Racing
  • UHMW skid plates: Holz Racing Products
  • Lock & Ride ice-chest mount: Lonestar Racing
  • Lock & Ride fuel-can mount: Polaris
  • Chassis Bones: ATR
  • Engine mounts: Holz Racing Products
