1964-1972 GM A-Body, 1969-1972 Grand Prix & 1970-1972 Monte Carlo Rear Coil-Over Conversion Kits

QA1 offers bolt-in Rear Coil-Over Conversion Kits for 1964-1972 GM A-body vehicles such as Chevelle, Cutlass and Regal, as well as 1969-1972 Grand Prix and 1970-1972 Monte Carlos. These kits include specially designed USA-made mounting brackets, single, double, or MOD™ Series adjustable aluminum shocks specific to 1964-1972 GM A-bodies, 1969-1972 Grand Prix and 1970-1972 Monte Carlos, high travel 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. MOD™ Series shocks also feature a double adjustable design but include adjustable low-speed bleed as well for fully independent control over compression and rebound characteristics.

These shocks also utilize a fully threaded body allowing for ride height adjustability. 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 kits and the addition of the rear coil-over conversion kit, you can now get a complete suspension makeover for both ends of the vehicle.
