QA1 stock mount shocks have been engineered specifically for oval 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. QA1 stock mount shocks have the same high quality components and features as our other racer revalveable and rebuildable steel and aluminum racing shocks. Due to deviations from the factory ride height, it may be necessary to check the static ride height of your particular application.
