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

When you're looking to get the most out of your G-Body or S10's suspension, this set of UMI Performance tubular front lower A-arms is a solid choice. What you get in this package are fully assembled A-arms, complete with UMI-designed and manufactured Delrin bushings, polyurethane bump stops, and premium 1/2" taller-than-stock ball joints. This kit also includes the necessary M12 Grade 10.9 hardware for installation. These arms are built to bolt on directly, working with factory spindles and compatible with factory springs, lowering springs, and hybrid coil-over kits.

These aren't just any A-arms; they're UMI's flagship design, fabricated from strong DOM tubing with precision CNC-machined tube ends. They're jig-built and TIG welded in critical areas for accuracy and strength, ensuring they fit right every time and can handle serious use on the street, drag strip, or track. The Delrin bushings are key here, offering smooth, bind-free suspension travel for improved steering precision and a more connected feel to the road, while still providing some insulation from road noise. The 1/2" taller ball joints are a smart addition, lowering the vehicle by 1/2", increasing spindle height, and helping to correct bump steer, especially beneficial on lowered vehicles. UMI also designed these arms to offer additional tire clearance.

This set is designed to fit a wide range of vehicles, including popular models like the 1978-1987 Buick Regal, 1978-1988 Chevrolet Monte Carlo, and 1982-2003 Chevrolet S10. For the best handling performance, UMI recommends pairing these lower A-arms with their compatible upper A-arms. These are proudly designed and manufactured in Philipsburg, PA, and come in your choice of a durable red or black powder coat finish.
