Bilstein 21-22 Polaris RZR Turbo S4 Black Hawk Powersports Shock & Coil Spring Assembly - Rear

Bilstein is well-known for their suspension components, and their Black Hawk Powersports coilovers are built to significantly improve your UTV's performance. This rear assembly is a direct fit for your 2021-2022 Polaris RZR Turbo S4, designed to take your off-road experience to the next level. It features Bilstein’s patented ZoneControl position sensitive damping, which uses 5 independently tuned zones—3 for compression and 2 for rebound—to manage the suspension's travel effectively.

What really sets these coilovers apart is the advanced damping technology. The internal Jounce Cut Off (JCO) system acts like a two-stage hydraulic bump stop, and a 10-position clicker lets you fine-tune how it controls bottoming out. For rebound, the Rebound Cut Off (RCO) feature helps settle the vehicle during suspension droop, protecting the damper and potentially eliminating the need for a limit strap. You get four external adjustments: high and low-speed compression, rebound, and the JCO, all easily accessible for quick changes on the trail.

These coilovers are constructed from all-aluminum with gold finned reservoirs, giving them a robust appearance and good heat dissipation. They come with dual-rate coils and crossover nuts, making it simple to adjust ride height and spring preload. Built to withstand race conditions right out of the box, this versatile package offers a comfortable ride with excellent control over bottoming out, giving you that sought-after “bottomless” feel on rough terrain.
