QA1 Pro Coil System Single Adjustable for Buick

Easy Bolt-In Installation
Minimal modifications to be made. Remove the existing shocks and springs and the QA1 Pro Coil System bolts right back in.
Specially Designed Conical Springs This spring is designed so that the lower end sets on the coil-over shock and the upper end sets in the original spring bucket in the frame. This allows for the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability is also achieved by locating the spring pressure in the frame and not on a single stud.
Ride Height Adjustable
Threaded aluminum body allows ride height adjustment.
These shocks are revalveable and rebuildable by
