Info

These QA1 GM Pro Coil Systems are a great option for anyone looking for fully adjustable ride height and valving control. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling.

  • In this episode, Project Chevelle gets coilovers and a much-needed altitude adjustment. Watch as we install QA1 bolt-on coilover kits front and rear, then dial in the perfect stance and shock settings. Our old Chevelle is really starting to look mean!
  • Speedway Motors employee Steve is back to work on his 1976 Chevrolet Laguna, this time installing a QA1 Coilover kit in his front suspension.
