These direct fit coilovers offer position sensitive damping and 4-way adjustability, all features that will take your UTV to the next level. Black Hawk Powersports feature Bilstein’s patented ZoneControl position sensitive technology that contains 5 independently tuned damping zones; 3 Compression and 2 Rebound. ZoneControl incorporates an internal Jounce Cut Off system (JCO) which is effectively a 2-Stage hydraulic bump stop. The JCO has a 10-position clicker that allows the rider to fine tune bottom out control. For Rebound, ZoneControl features a Rebound Cut Off (RCO) that acts to settle the vehicle at the final stage of suspension droop. The RCO will protect the damper, eliminating the need for a limit strap. Black Hawk Powersports offer 4 unique external adjustments; High\/Low speed compression, rebound, and JCO. All easily accessible and ready for quick damping changes on the fly. Bilstein Black Hawk powersports are an all-aluminum design with gold finned reservoirs. All applications come with Dual Rate Coils and crossover nuts for easy ride height and spring preload adjustments. Black Hawk Powersports are completely serviceable and designed to withstand race conditions right out of the box. This extremely versatile coilover package will provide excellent comfort and unsurpassed bottom out control.
