UMI Performance 78-88 G-Body 82-03 S10/S15 73-77 A-Body Front Coilover Kit

If you're looking to dial in your suspension for everything from street cruising to serious track time, this front coilover kit from UMI Performance is a solid option. It's built around Viking's double-adjustable shocks, which give you 19 positions for both compression and rebound damping. This means you can fine-tune your ride for drag racing, autocross, road racing, or just a comfortable street feel, all with the same set of shocks. The kit uses a hybrid coil spring that fits directly onto your vehicle's upper spring perch, and the adjuster on the shock acts as the spring compressor, so you won't need a separate spring compressor tool for installation. This kit fits a wide range of vehicles, including popular models like the 1978-1987 Buick Regal, 1982-2003 Chevrolet S10, and 1978-1988 Monte Carlo.

You get to choose the spring rate that best suits your needs, with options ranging from 250 lb for dedicated drag use to 550 lb for handling-focused street or big-block applications. The shocks themselves are built, dyno-tested, and serialized in Lakeville, Minnesota, and feature a brilliant protective finish to keep them looking good. For increased reliability and performance, especially in demanding applications like autocross or road racing, the bearing-mounted bottom shock attachment is recommended over the polyurethane option. While the thrust bearing and spanner wrench kit is optional, it's highly recommended for making ride height adjustments easier, allowing you to lower your vehicle from stock height down to 3 inches.

This kit is designed to work with UMI's lower A-arms or your factory lower A-arms, and pairs exceptionally well with UMI's geometry-corrected upper A-arms for a complete suspension overhaul. Remember that performance bushings, whether poly or bearing, can feel and sound different than stock rubber components.
