65-70 GM B-Body Rear Lower Control Arm

The 65-70 GM B-Body Rear Lower Control Arm (Part No. 3655-B) from UMI Performance is designed specifically for muscle car enthusiasts and restoration specialists looking to enhance the handling of classic Chevelle, Malibu, and Monte Carlo platforms. This component addresses the vague, worn rear suspension geometry that is common in original equipment, aiming to restore proper wheel alignment and improve cornering stability.

Manufactured to tighter tolerances than factory originals, the UMI Performance 3655-B control arm reduces compliance in bushing pivot points, which helps maintain consistent suspension geometry. The design focuses on improving the performance of the rear suspension by addressing issues that arise under cornering loads and braking stress in vintage B-Body vehicles.

This rear lower control arm is specifically engineered for 1965–1970 GM B-Body vehicles, making it an ideal replacement for Chevrolet Chevelle, Malibu, El Camino, and GTO models. It is a foundational upgrade that enhances tire contact patch consistency and directional stability, especially beneficial when upgrading brakes and tires on classic American muscle cars.
