QA1 Pro Coil® System Double 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 QA1 Authorized Service Centers
