PUSH Industries ACS3 Coil Component Kit

The ACS3 coil system significantly improves small-bump sensitivity and traction by eliminating the stiction often found in air springs. You get a more consistent, supple feel throughout the travel, which helps the tire track better over technical terrain.

The Air Bump Stop acts as a secondary, adjustable air spring that engages only at the end of your travel. It provides bottom-out control, allowing you to run a lighter coil spring for better traction without worrying about harsh impacts on big hits.
