With an unwavering dedication to engineering excellence, their team has meticulously crafted a range of products that elevate the Polaris RZR XP's capabilities to new heights.
1) FOX RC2 Shocks
Considering that all trim levels of the RZR XP come with Walker Evans shocks, the FOX RC2 Shocks provide a major performance upgrade, unleashing the full potential of the Polaris RZR XP.
2) Dual Rate Spring Kit
The Dual-Rate Spring Kit provides for increased ride height, increased bottom-out resistance, reduced bucking, smoother ride quality over chop and chatter. Tailored to the individual’s needs and unit specifications, Shock Therapy considers driver weight, aftermarket accessories, terrain, driving style, and more.
3) Tie Rods
The stronger, end-to-end solution that retains alignment of factory geometry, Shock Therapy Tie Rods for the RZR XP come precision machined from high-strength 7075 billet aluminum. The inner joint retains stock geometry, has a larger ball and socket for extended life, and larger threaded stud to tie rod connection for added strength. The outer joint features their patented BSD (Bump Steer Delete) Kit, whose height-adjustable spacers eliminate bump steer.
4) Radius Rods
The Radius Rod Kits for the Polaris RZR XP come with stainless steel spacers and the highest quality, 3/4-inch teflon lined rod ends for strength and longevity.
5) Sway Bars, Sway Bar Links (front and rear)
Shock Therapy’s Sway Bar Link Kits and Sway Bars (front and rear) replace the factory links with a simple bolt-on kit. The design uses high-quality frame mount bushings and billet aluminum mounting clamps that spread the load over a wider area. Plus, it has three adjustable settings. In its softest position, it is 50 percent stiffer than the stock sway bar, the next position is 60 percent stiffer, and the last position is 70 percent stiffer –– allowing you to tune how much body roll you want removed from your RZR XP depending on the driving conditions.
6) Limit Straps (front and rear)
Especially as one get’s bigger tires and wheels on their rig, the ‘clunking’ sound of the shocks dropping out and hanging on the top-out spring is probably a familiar one. Originally tuned for the factory wheel and tire settings, the internal spring will not be stiff enough to arrest extension with heavier aftermarket upgrades –– making Limit Straps a must-have.
Shock Therapy's patented design features a billet aluminum, laser-engraved upper mount and also prevents the strap from interfering with or getting tangled on other parts when the shock compresses and the strap’s slack increases. Set apart from most other options too, Shock Therapy’s Limit Straps not only adjust but bolt directly to the shock itself –– allowing the strap to be perfectly in line with the shock, thereby limiting the leverage exerted on it and increasing strap life.
7) Ride Improvement System
Shock Therapy’s Ride-Improvement System (RIS) drastically modifies the internals of the shock for a major upgrade in performance –– with internal valving custom-tailored to the driving style of each unit and the different terrains one tackles. The modifications inside the shock result in superior handling and plushness through small chop and chatter, increase bottom-out resistance at full compression, and remove excessively stiff ride quality at moderate & low speeds. Far from being only for racing applications, Shock Therapy’s RIS also supports recreational riders looking to get the most out of their suspension.
8) Steering Rack
The Shock Therapy’s Race Rack and Pinion for the Polaris RZR XP boasts many impressive features that set it apart from other steering racks, including:
- 7075 Aluminum construction
