1964-1972 GM A-Body Coil Over Conversion Brackets, Rear
Hardware included
he kit includes a reinforced upper mount, designed for a 2-1/2” racing coilover with a double-shear mount. The FEA designed reinforced lower brackets bolt directly over the stock rear lower control arm mounts and have a trailing arm height adjustment for instant center location tuning.
Manufactured and raced out of Philipsburg, PA-USA, using US materials.
We recommend installing the brackets first and measuring center to center at ride height to ensure accurate shock part numbers. For fitment, this kit is a direct bolt-on when used with a GM axle housing and stock GM brackets.
For installation, welding is required for drag use for vehicles running 10.50 or faster or using slicks. Bolted brackets are suitable for street performance, auto-x, and road race applications.
Fitment Note: For stock axles only. Rear shocks may not clear all exhaust tail pipes.
