QA1 "R" Pro Coil???? System For Buick

Unmatched Performance on the Strip for
Stock GM Front Ends
Engineered for Drag Racing
Firm compression with a wide range of rebound adjustment for front
drag racing applications.
Easy Bolt-In Installation
Minimal modifications to be made. Remove the existing shocks and springs and the QA1 "R" Series 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
