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

If your classic GM A-body's front end is showing its age with worn-out, crusty lower control arms, UMI Performance has a solid solution. These brand-new tubular front lower A-arms are built from strong DOM tubing with precision-fit CNC machined tube ends. They're jig-built to ensure they bolt on correctly every time, and all critical areas are TIG welded for strength and a clean look. This design also offers improved ball joint angles, which is especially helpful for lowered vehicles, and provides extra tire clearance.

These A-arms come fully assembled and ready for installation, including greaseable polyurethane bushings, premium ball joints, polyurethane bump stops, and spring isolators. UMI Performance has tested these arms extensively on the street, drag strip, and skid pad, so you can trust they're built to handle all sorts of driving. They're designed to work with factory springs, lowering springs, and coil-over kits without needing to change the A-arms themselves. For an even more dialed-in handling setup, UMI recommends pairing these with their upper A-arms (P/N 4033-1).

This part fits a wide range of classic GM vehicles, including popular models like the Chevrolet Chevelle, Buick Skylark, and Pontiac GTO. A hardware kit (Part # 4001) with Grade 8 bolts, washers, and nylock nuts is included to ensure a straightforward bolt-on installation. These are proudly designed and manufactured in Philipsburg, PA, USA, and are available in a durable red or black powder coat finish.
