UMI Performance 78-88 G-Body S10 Tubular Front Upper & Lower A-Arms Poly

UMI Performance is known for making well-built suspension components that help you get the most out of your vehicle's performance. If you're looking to improve the handling and steering feel on your 1978-1988 G-Body or S10 truck, this tubular front upper and lower A-arm kit is a solid option. It replaces the factory stamped steel arms with a much stronger, jig-built tubular design that's designed to handle more aggressive driving conditions.

These A-arms are assembled with a mix of durable materials for a precise feel. The lower arms use greaseable polyurethane bushings that offer a good balance of handling and ride comfort, while the upper arms feature UMI's own Delrin bushings and CrMo cross shafts. The ball joint mounts have been adjusted to work with lowered vehicles and offer extra wheel clearance. UMI also includes recommended alignment specs and detailed installation instructions to help you get the best results. This kit comes fully assembled and ready to bolt on, and it's designed to work with factory springs, lowering springs, or coil-over kits.

This kit includes everything you need for installation, including premium ball joints and polyurethane bump stops. The TIG-welded DOM tubing and durable powder coat finish ensure these arms will look good and perform well for a long time. For even more advanced geometry changes, UMI offers a kit with a taller upper ball joint for improved camber control.
