Product details
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. Control arm braces are manufactured from DOM steel; TIG welded and feature adjustment for a perfect fit on all 1964-1967 A-Body’s. Kit includes new longer Grade 8 hardware, nuts and washers. 4029 - 1964-1967 GM A-Body Control Arm Reinforcements/Frame Braces
