These kits provide the highest quality performance characteristics for your Mustang II front end. The springs are designed specifically for use with the QA1 coil-over shocks and the factory upper spring pocket. This enables the use of a longer spring, which allows for a lighter overall spring rate. By building the upper section of the spring to factory dimensions, this puts the weight back into the frame instead of on a single stud.

Q & A
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.
Product guru Jeff K. takes us along as he updates the suspension on his 1946 Ford Sedan Delivery with a set of fresh Mustang II coilovers following an unfortunate incident with a pothole.
Speedway Motors shares a How-To of selecting the right coilovers for your T-Bucket.
See how Jeff converts his 1967 Chevelle rear suspension to QA1 double adjustable coil-over suspension. This allows added adjustability for ride height and compression and rebound characteristics.
We add some tuneability to the suspension on Project Chevelle by bolting on QA1 coilovers front and rear.
Learn how to mount coil-overs with this guide. We can help you find your spring rate, compensate for mounted angle, and measure your replacement shock.
