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

If you're looking to replace worn-out, crusty lower A-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 added strength and a clean appearance. A notable design improvement is the adjusted ball joint angle, which helps with lowered vehicles and provides extra clearance for larger tires.

What really sets these apart is the inclusion of UMI's own greaseable Delrin bushings. Delrin offers a smooth suspension action and precise control, while still absorbing some road noise. They come pre-assembled with polyurethane bump stops and spring isolators, plus premium ball joints are already installed. UMI has tested these arms extensively on the street, drag strip, and skid pad, so you know they're built to handle a lot of abuse. They're designed to work with your factory springs, lowering springs, or coil-over kits. For an even better handling setup, UMI recommends pairing these with their upper A-arms (part # 4033-1).

These A-arms come fully assembled and ready for installation, and they include a hardware kit with Grade 8 bolts, washers, and nylock nuts. They are designed and manufactured in Philipsburg, PA, USA, and are available in a durable red or black powder coat finish.
