QA1 Proma Star

Double Adjustable Shocks

If you’re looking for hard-core performance and truly independent compression and rebound adjustment, the Proma Star Double Adjustable Shock is what you need. The double adjustable shocks have 324 valving options, with 18 positions of compression adjustment and 18 positions of rebound adjustment.

QA1’s double adjustable range encompasses virtually every application, with soft settings for a comfortable ride and extremely stiff settings for hard core performance handling. With evenly spaced valving changes throughout the adjustment range, there are no jumps when adjusting between any two clicks. Each adjustment has been carefully defined to provide the ideal force curve to maximize performance.

QA1 Proma Star

Single Adjustable Shocks

With QA1’s Proma Star Single Adjustable coil-over shock, you can easily adjust your compression and rebound valving and get the hard-core performance you need. One knob allows you to choose from 18 valving options that adjust both compression and rebound valving simultaneously, allowing total suspension control in one easy-to-reach location.
