QA1 offers bolt-in Rear Coil-Over Conversion Kits for the 1973-1977 Pontiac Grand Prix. These kits include specially designed USA made mounting brackets and single or double adjustable Aluminum Shocks, springs and all necessary hardware. Single Adjustable Shocks provide 18 positions of simultaneous rebound and compression adjustment while QA1’s double Adjustable Shocks provide 18 positions of compression adjustment and 18 positions of rebound adjustment, for a total of 324 possible valving combinations. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling. Specially designed for QA1’s Pro Coil Systems, the American-made lightweight High Travel Springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance.

Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications. With our highly popular adjustable front Coil-Over Kit and the addition of the rear coil-over conversion kit, you can now get a complete suspension makeover for both ends of the vehicle.
