64-72 GM A-Body Rear Lower Control Arms

The UMI Performance 64-72 GM A-Body Rear Lower Control Arms (part 4024-B) are designed for classic muscle car restorations and performance builds. These control arms are essential for enhancing chassis-level suspension geometry control, particularly for vehicles that have undergone significant power upgrades or are used in track applications.

Constructed from high-strength steel and finished with a durable black powder coat, these tubular trailing arms improve rear axle location and reduce squat during acceleration. The use of polyurethane bushings enhances compliance and durability compared to factory rubber, resisting degradation from heat and environmental factors. The tubular design also minimizes unsprung weight while maintaining the necessary rigidity for consistent handling.

These control arms are specifically designed for 1964–1972 GM A-Body vehicles, including Chevelle, Malibu, Cutlass, and Skylark platforms. Owners looking to improve ride quality, reduce chassis flex, or tune their suspension for street or strip applications will find these arms indispensable. Proper installation requires alignment checking to ensure that suspension geometry meets specifications.
