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 track days, this front coilover kit from UMI Performance is a solid option. It's designed to fit a range of popular rear-wheel-drive platforms like the 1978-1988 G-Body cars, the 1982-2003 S10/S15 trucks, and the 1973-1977 A-Body models. This kit replaces your stock shocks and springs with a fully integrated coilover system, giving you the ability to fine-tune your ride height and damping characteristics.

The heart of this kit is the Viking double-adjustable shock, which offers 19 distinct positions for both compression and rebound. This means you can independently adjust how the shock controls the upward and downward movement of your suspension, allowing you to tailor the feel for drag racing, autocross, road racing, or just a more comfortable street ride. The hybrid coil springs are designed to work with the coilover shock body, eliminating the need for a separate spring compressor during installation. You can choose from several spring rates, from a 250 lb/in option for dedicated drag cars to a 550 lb/in rate for handling-focused applications, ensuring you get the right setup for your needs. The shocks are also rebuildable, meaning this is a long-term upgrade for your vehicle.

For easier ride height adjustments, UMI Performance recommends the optional spanner wrench and thrust bearing kit. The thrust bearing sits between the spring seat and the spring, making it much smoother to turn the adjustment collar. The spanner wrench itself is essential for making these height changes while the shock is installed. You'll also need to consider the lower shock mount option: polyurethane bushings are available for a more comfortable street feel, while bearing ends are recommended for high-performance applications like drag racing or autocross where durability and precise feedback are critical. This kit is designed to work with UMI's own control arms or your factory lower control arms, and pairs well with UMI's geometry-corrected upper control arms for an even more refined front suspension setup.
