4057 -1964-1972 GM A-Body Rear Coilover Bracket Kit

UMI’s bolt-in rear coilover kit allows full ride height, spring rate and damping adjustments, while trailing arm adjustment enables fine tuning of instant center. The reinforced upper mount is a direct bolt-in (requiring one additional hole to be drilled) and holds a true 2-1/2” racing coilover with double-shear mount. The FEA designed reinforced lower brackets bolt directly over the stock rear lower control arm mounts, utilizing the existing lower shock hole(s) (may requiring drilling of additional hole depending on factory configuration). The 2-hole trailing arm height adjustment enables fine tuning of instant center location for drag launch or auto-x/road race rear steer tuning. 100% designed, manufactured and raced out of Philipsburg, PA-USA and always US materials.Stock Axle Only: : This kit is a direct bolt-on only when used with a gm axle housing and stock gm brackets. aftermarket housings vary widely in design and layout, which means the 4057 bracket will not bolt on.Note: Rear shocks may not clear all exhaust tail pipes.
