Lower StrongArms 64-72 GM A-Body

The Lower StrongArms 64-72 GM A-Body control arm from RideTech is the go-to suspension upgrade for vintage Chevy, Pontiac, Oldsmobile, and Buick A-Body platform restorations and high-performance builds. If you're tackling a frame-off restoration or modernizing the handling geometry on a classic muscle car, these lower control arms replace worn OEM units that have lost clearance and geometry precision after decades of road miles. Built by RideTech—a suspension specialist trusted by hot rodders and professional builders—this component addresses the fundamental weakness in original A-Body designs: outdated pivot geometry and excessive compliance.

These lower control arms feature precision-machined construction designed to tighten suspension geometry and improve front-end response during acceleration, braking, and cornering. The design maintains proper wheel alignment angles while accommodating modern coilover or traditional spring-and-shock setups without modification to the core mounting points. At 38.5 lbs per pair, the arms are engineered to handle increased loads from engine upgrades and stiffer suspension components common in restomod applications. The robust construction resists flex under hard acceleration, reducing geometry changes that degrade handling predictability—critical when upgrading brake systems or adding power steering to cars originally equipped with manual steering.

Installation fits all 1964–1972 GM A-Body vehicles, including Chevrolet Chevelle, Pontiac GTO and LeMans, Oldsmobile Cutlass, and Buick Skylark models. Whether you're performing a two-weekend handling upgrade or a complete suspension overhaul, these control arms bolt directly to stock mounting points, eliminating the need for extensive fabrication or frame modification. They work seamlessly with both stock-height restorations and lowered builds, making them equally valuable for the purist who wants OE-style appearance with modern precision or the enthusiast chasing track-ready geometry. Pair them with a quality alignment afterward to unlock the full benefit of RideTech's engineering.
