This is the most complete high performance long travel suspension system available for the Polaris RZR Razor. This suspension system was put together for both the competitive racer and recreational enthusiast alike that want the very best in suspension performance. This system uses Chromoly tube A arms that are TIG welded and 4″ longer than stock. These arms move the overall track width out 8″, dramatically increasing the RZR’s suspension wheel travel and stability. These arms are matched with Elka Performance Coilover Shocks that are custom valved and tuned for this system. Also included in this system is All Terrain Research’s Polaris RZR Rear Chassis Ribs, front and rear Chassis Bones, and Rear A-Arm Braces. Strengthening the Polaris RZR’s frame is an absolute necessity with using a long travel suspension.
