64-72 GM A-Body Upper/ Lower A-Arm Mounting Kit

The 64-72 GM A-Body Upper/Lower A-Arm Mounting Kit is a precision suspension upgrade engineered for classic General Motors A-Body vehicles spanning model years 1964 through 1972. Built by UMI Performance, a leader in high-performance chassis components, this kit addresses the critical foundation of any serious restoration or performance build: the control arm mounting geometry. Whether you're restoring a Chevelle, Skylark, or GTO to show quality or preparing a muscle car for road course duty, this mounting kit provides the structural integrity and adjustability that separates a competent suspension from an exceptional one.

This kit delivers precision-engineered upper and lower mounting points that allow for proper control arm alignment and geometry correction on stock or modified A-Body frames. The carefully calculated design supports both OEM ride height and lowered applications, accommodating variations in chassis flex and frame condition common to vehicles nearly 50 years old. Weighing just 1.86 lbs while maintaining robust structural capability, the components are manufactured to exacting tolerances that ensure repeatable installation and long-term durability. The compact footprint—measuring 3.7 x 1.55 x 5.7 inches—allows for efficient integration without unnecessary bulk or interference with brake lines, wiring, or fuel system routing.

Restoration specialists, performance builders, and vintage car enthusiasts benefit most from this kit when undertaking complete chassis refurbishment or addressing worn factory mounting points that compromise handling and tire wear. Installation requires basic mechanical aptitude and standard hand tools; the straightforward design integrates seamlessly with OEM suspension components while serving as the foundation for coil-over or performance spring conversions. Compatibility extends across all 64-72 GM A-Body platforms, making this a versatile solution for Chevrolet Chevelle, Pontiac GTO, Oldsmobile Cutlass, and Buick Skylark models. Proper installation of this mounting kit is essential before alignment work and should precede any suspension fine-tuning or performance validation.
