Lower 68-72 Chevelle LH

The Lower 68-72 Chevelle LH control arm by U-B Machine is a precision-engineered suspension component designed for classic muscle car restoration and performance upgrades. This left-hand lower control arm serves as a critical pivot point in your Chevelle's front suspension geometry, controlling wheel movement and maintaining proper alignment under acceleration, braking, and cornering loads. Whether you're rebuilding a stock restoration or upgrading a modified street machine, this component is essential for safe, predictable handling.

U-B Machine manufactures this control arm to OEM-quality specifications, ensuring consistent dimensions and material integrity across the 1968–1972 Chevelle platform. The control arm assembly manages the vertical travel of the wheel hub while maintaining the correct camber and caster angles throughout suspension articulation. Proper control arm condition directly impacts tire wear rates, steering response, and overall chassis stability—worn or bent units introduce wandering, uneven tire wear, and compromised safety. At 10.145 lbs with compact overall dimensions of 13.8 x 6.5 x 17.2 inches, this component integrates seamlessly into the factory suspension mounting points without modification.

This lower control arm is ideal for Chevelle owners performing frame-off restorations, suspension refreshes, or upgrading to modern bushings and ball joints for improved performance. The left-hand designation ensures proper fitment on the driver's side of the vehicle, and compatibility extends to all 1968–1972 Chevelle models regardless of engine or transmission configuration. Installation requires basic mechanical knowledge and standard suspension tools; pair this component with matching right-hand control arms, ball joints, and bushings for complete front-end renewal. Verify fitment with your specific model year and suspension type before purchase to ensure correct geometry and alignment results.
