Description

Control Arm Brace - Bolt-On - Steel - Black Powder Coat - GM A-Body 1968-72 - Pair

UMI Performance 68-72 GM A-Body Control Arm Reinforcements/Frame Braces

Trailing arm mount braces are designed to reinforce the upper and lower front control arm mounts on your classic A-Body. The more power your ride makes the better chance of bending or breaking the rear control arm mounts. These tubular reinforcements tie the upper and lower control arm mounts together for added strength and driving performance. The UMI Performance braces are bent to contour the floor of the vehicle, unlike our competitor's designs these reinforcements do not require the floor to be dented or pounded for correct fitment. Control arm braces are manufactured from DOM steel; TIG welded and feature adjustment for a perfect fit on all 1968-1972 A-Body's. Kit includes new longer Grade 8 hardware, nuts and washers.
