Factory racks fail. Aftermarket racks add bump steer. The Shock Therapy Race Steering Rack is the only billet rack engineered to eliminate bump steer while preventing catastrophic rack failure. Built from 7075 aluminum with a massive 1"x1" square rack gear, this is the last steering rack you'll ever need for your Polaris RZR RS1 or General XP 1000.
⚠️ IMPORTANT: This rack requires aftermarket tie rods with 5/8" rod ends on each end. Not compatible with stock tie rods.
⚠️ RACE PART NOTICE: This rack is designed for RACING. Race parts will wear out eventually and need periodic rebuilding. Race parts have no warranty.

After 1500 race miles, Shock Therapy's shop XP Turbo with 32" tires experienced catastrophic rack failure—the factory rack sheared in half at the center of the splined rack gear. Aftermarket replacements were barely .085" thicker at the same failure point and added dangerous bump steer by widening tie rod pivot points up to 1.5". This creates unpredictable steering, accelerated wear on ball joints and bearings, and a car that "hunts" for direction over every bump. The Shock Therapy Race Rack solves both problems with a massive square rack gear and factory-correct pivot width.
"After breaking two factory racks, I switched to the Shock Therapy rack and haven't looked back. Zero bump steer and it's survived an entire Best in the Desert season without issues."
— Tom R., Desert Racer
"The steering feel is night and day better. No more fighting the wheel over whoops and the faster ratio makes technical sections so much easier. Worth every penny."
— Lisa M., Rock Crawling Champion
