The QA1 GM Pro Coil System is a front coil-over conversion built for second generation Camaro and Firebird applications that calls for fully adjustable ride height and valving control. The fully threaded billet aluminum shock body sets ride height for the desired stance and helps fine-tune weight balance, while the single adjustable valving tunes the ride. QA1's American-made lightweight high travel springs use fewer coils and a smaller wire diameter for increased travel, reduced unsprung weight and faster response. It is an easy bolt-in install carrying a best-in-class warranty and is made in the USA.
