UMI Performance 78-88 G-Body S10 Tubular Front Lower A-Arms Delrin

If you're looking to seriously improve the handling of your classic G-Body or S10 truck, UMI Performance's flagship tubular front lower A-arms are a solid choice. These aren't just standard replacement arms; they're built with performance in mind, featuring bind-free Delrin bushings and 1/2" taller-than-stock ball joints. This combination works to give you smoother suspension travel and a noticeable increase in steering precision, making your vehicle feel more connected to the road. The taller ball joints also help lower the vehicle slightly, add crucial spindle height, and correct bump steer, all in one package.

UMI fabricates these lower A-arms from strong DOM tubing with CNC machined ends for a precise fit, and they're jig built to ensure accuracy and a bolt-on installation. Critical areas are TIG welded for strength and a clean appearance. The Delrin bushings, which are preloaded with polyurethane bump stops, offer smooth suspension action while still providing some insulation from road noise. These arms are designed to work with factory springs, lowering springs, and coil-over kits, and they also offer improved ball joint angles for lowered vehicles and extra tire clearance. They come fully assembled with a hardware kit, ready for installation.

For even more enhanced performance, UMI recommends pairing these lower A-arms with their upper A-arms, like part numbers 3056-2 for corner carving or 3056-3 for ultimate road race handling. These arms are designed and manufactured in Philipsburg, PA, USA, and are available in a durable red or black powder coat finish.
