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

Fabricated from strong DOM tubing with CNC machined tube ends, these UMI Performance tubular front lower A-arms are built for a precise fit on your 1964-1972 GM A-Body vehicle. If you're tired of worn-out factory control arms with cracked ball joint bosses, this is a solid upgrade. They are jig built and TIG welded in critical areas, ensuring superior strength and a clean look that holds up to street driving, drag strip action, and skid pad abuse. The design also offers improved ball joint angles, which is particularly helpful for lowered vehicles, and provides extra tire clearance.

These A-arms come fully assembled and ready to bolt on, including greaseable polyurethane bushings, premium ball joints, polyurethane bump stops, and spring isolators. They are designed to work with factory springs, lowering springs, and coil-over kits without needing to change the A-arms themselves. For an even more comprehensive handling improvement, UMI recommends pairing these with their upper A-arms (P/N 4033-1). The included hardware kit features Grade 8 bolts, washers, and nylock nuts for a secure installation. These are designed and manufactured in Philipsburg, PA, USA, and are available with a durable red or black powder coat finish.
