Bilstein M 9400 (Coilover) Black Hawk shock absorbers are built to dominate off-road terrain with race-proven performance and precision tuning. Featuring 4-way adjustability and multiple stroke lengths these universal coilovers adapt to a wide range of UTV and off-road setups. At the core is Bilstein’s patented ZoneControl technology—five independently tuned damping zones (3 compression 2 rebound) with an internal Jounce Cut Off (JCO) and Rebound Cut Off (RCO) for bottom-out and droop control—no limit straps needed. The JCO acts as a two-stage hydraulic bump stop and includes a 10 position adjustment for fine tuning the bottom out control. The RCO engages in the final stage of droop to give more control and protect the damper. 9400 Black Hawk Powersports dampers provide 4 unique external adjustments that are easily accessible; high/low speed compression rebound and JCO. Crafted from lightweight aluminum with gold-finned reservoirs these coilovers are fully serviceable and track-ready out of the box. Springs and coilover hardware sold separately for custom comfort and performance. Upgrade your offroad or UTV experience with Bilstein’s unique “bottomless” ride on the 9400 Black Hawk Powersports universal coilover dampers
