UMI Performance 4028-B Control Arm Reinforcements and Frame Braces for 1964-1972 GM A-Body

Fits 1964-1972 GM A-Body vehicles including Chevrolet Chevelle and El Camino, Pontiac GTO and LeMans, Oldsmobile 442 and Cutlass, and Buick Skylark and Special.

Reinforce your classic GM A-Body chassis with UMI Performance trailing arm mount braces. As power levels increase, factory rear control arm mounts become a weak point, prone to bending or breaking under heavy torque loads. These tubular reinforcements tie the upper and lower control arm mounts together, significantly increasing structural rigidity and improving driving performance.

UMI Performance braces are manufactured from high-strength DOM steel and precision TIG welded for maximum durability. Unlike many competing designs, these braces are specifically bent to contour to the vehicle's floor pan, ensuring a correct fitment without requiring you to dent or modify the floor. Each kit (MPN 4028-B) is adjustable for a perfect fit and includes all necessary heavy-duty hardware.
