These upper rear control arm bushings are engineered exclusively for 1964 to 1972 GM A-Body platform vehicles, including classic GM muscle cars such as Chevelle, Cutlass, GTO, Skylark and LeMans.

Installed between the upper rear control arm and vehicle chassis, the bushings serve as flexible vibration-dampening connectors for the rear suspension assembly. Original factory rubber bushings degrade over decades from road shock, grease corrosion and thermal aging, resulting in sloppy rear wheel alignment, wandering steering, uneven tire wear and degraded handling performance during acceleration and cornering.

Available in OEM-style natural rubber or high-performance polyurethane formulations:

● OEM rubber versions replicate factory stock damping characteristics, delivering comfortable daily driving with stock-level noise isolation.

● Polyurethane variants feature higher rigidity to minimize suspension deflection, sharpen rear suspension responsiveness, ideal for street performance, drag racing and classic restoration builds.

Direct bolt-on replacement design requires no chassis modification, matching original mounting dimensions of GM A-Body factory control arms for straightforward DIY or professional garage installation. Restores factory rear suspension geometry, corrects improper camber and toe settings, and brings back stable braking and cornering capability for vintage GM A-body classics.
