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

Bilstein is known for making well-built suspension components that perform. This Black Hawk Powersports coilover assembly is designed specifically for your 2021-2022 Polaris RZR Turbo S4, aiming to significantly improve its handling and ride quality. It's a direct fit for the front left corner, meaning it's built to bolt right on without needing modifications, making the upgrade process smoother.

What sets this coilover apart is its advanced ZoneControl position-sensitive damping. It features 5 independently tuned zones—3 for compression and 2 for rebound—along with an internal Jounce Cut Off (JCO) system that acts like a two-stage hydraulic bump stop. This JCO has a 10-position clicker to help you fine-tune how the suspension handles hard impacts and prevents bottoming out. For rebound, there’s a Rebound Cut Off (RCO) that helps settle the vehicle after suspension extension, which can even eliminate the need for a limit strap and protect the damper. You get four external adjustments: high-speed compression, low-speed compression, rebound, and the JCO, all easily accessible for on-the-fly tuning.

The assembly is constructed from all-aluminum with gold finned reservoirs, giving it a robust look and feel suitable for demanding conditions. It comes with dual-rate coils and crossover nuts, allowing for straightforward adjustments to ride height and spring preload. This coilover is completely serviceable, meaning it can be rebuilt, and it's built to handle race conditions right out of the box, offering a unique 'bottomless' ride feel with excellent comfort and control.
