UMI Performance 64-72 GM A-Body Rear Shock Tower Brace - Black is UMI Performance manufacturer part number 4065-B, selected by the verified year, make, and model applications below. Strengthen your classic GM A-Body with UMI’s 1964-1972 El Camino and Wagon Rear Shock Tower Brace. Designed specifically for models where standard braces interfere, this A-Body upgrade ensures proper clearance while reinforcing one of the most stressed areas of your suspension—the rear spring pocket. This rear shock tower brace is highly recommended when running coilover conversions, standard springs under heavy load, racing applications, or hauling duties. By stabilizing the rear suspension structure, it improves chassis rigidity, enhances handling, and provides additional durability for demanding use. Unlike universal braces, UMI engineered this El Camino/Wagon-specific component to fit cleanly without interference issues commonly found with other designs
Key Features
- All mounting hardware needed for a direct bolt-on installation is included.
- The UMI4065-B is purpose-built to clear that structure while still tying the rear shock towers together, stiffening the rear spring pocket area and cleaning up the wandering feel that comes from a flexing chassis under load.
- The UMI4065-B is a rear shock tower brace built specifically for 1964 to 1972 GM A-Body El Camino and wagon models.
- It ties the rear shock towers together to stiffen the rear spring pocket area while clearing the bed rails and floor pan that cause standard braces to interfere on these body styles.
- The UMI4065-B is designed specifically for El Camino and wagon body styles.
- Coupes and sedans require a different UMI shock tower brace.
