UMI Performance 64-72 GM A-Body Tubular Front Lower A-Arms Delrin Bushings

If you're looking to replace worn-out, crusty lower control arms on your 1964-1972 GM A-Body, UMI Performance has a solid solution. These tubular lower A-arms are built from strong DOM tubing with CNC machined ends for a precise fit, ensuring they bolt right on without issues. They're jig-built and TIG welded in critical areas for extra strength and a clean look, addressing common failure points on older suspension components.

These arms are designed with improved ball joint angles, which is especially helpful if your vehicle is lowered, and they also offer more tire clearance. Inside, you'll find UMI-designed and manufactured Delrin bushings. Delrin offers a good balance, allowing for smooth suspension movement and precise operation while still providing some isolation from road vibrations. They come pre-assembled with premium ball joints, polyurethane bump stops, and spring isolators, making them a complete package ready for installation. UMI has tested these extensively on the street and track, so you can expect them to hold up to various driving conditions. They work with factory springs, lowering springs, and coil-over kits, giving you flexibility in your suspension setup. For the best results, UMI recommends pairing these with their upper A-arms (part # 4033-1).

This kit includes everything needed to mount the new A-arms, including Grade 8 hardware. They are designed and manufactured in Philipsburg, PA, USA, and are available in a red or black powder coat finish.
