UMI Performance 1964-72 GM A-Body Rear Coilover Kits
UMI Performance 1964-72 GM A-Body rear coilover kits allow for ride height adjustments ranging from a -2 in. to -3 in. drop, along with spring rate and damping modifications.

It also features FEA-designed reinforced lower brackets that bolt directly over the stock rear lower control arm mounts and utilize the existing lower shock hole(s). The 2-hole trailing arm height adjustment enables fine-tuning of the instant center location for drag launches or autocross/road race rear steer tuning. Viking Performance shocks offer 19-way adjustments for both compression and rebound. The 2 1/2 in. coilover springs come in various rates suitable for drag use, street driving, and autocross/road racing. Please note that these kits are intended for a -2 to -3 in. Pro-Tour style lowering and are compatible only with factory GM axle housings. They may not fit aftermarket housings such as Quick Performance, Currie, or Moser.
