The most advanced stock mount racing shock! Every internal component is of the same design as our 50 Series bearing mount shocks. Racers love the durability, repeatability and performance of this shock. QA1's FC Series have more low-speed damping control than the competition. This means less bouncing, especially in heavier cars, resulting in on-track consistency.

QA stock mount shocks have been engineered specifically for circle track racing. They are racer revalveable and rebuildable, just like many of our steel bearing mount and aluminum shocks. Now there is no need to keep throwing damaged or worn-out shocks in the trash. Due to deviations from the factory ride height, it may be necessary to check to static ride height of your particular application.< /p>
