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
