UMI Performance 68-72 GM A-Body Control Arm Reinforcements/Frame Braces is UMI Performance manufacturer part number 4028-B, selected by the verified year, make, and model applications below. Trailing arm mount braces are specifically engineered to enhance the durability of the upper and lower front control arm mounts on classic A-Body vehicles. They provide crucial reinforcement, especially for high-powered rides that may put strain on the rear control arm mounts. These tubular braces effectively connect the upper and lower mounts, resulting in improved strength and overall driving performance. Unlike other designs on the market, UMI Performance braces are skillfully bent to match the contour of the vehicle's floor, eliminating the need for any alterations. Crafted from high-quality DOM steel and TIG welded, these braces also feature adjustable components to ensure a precise fit for all 68-72 A-Body models. The kit includes Grade 8 hardware for easy installation.
