Looking for performance handling but like the old school factory look? The UMI Stage 1 kit featuring factory height springs is designed to offer both! The Stage 1 is perfect for the A-Body owner who wants a simple and effective suspension upgrade with real handling improvement all while maintaining the factory muscle car look. This kit includes our trusted front sway bar and rear sway bar combined with UMI springs and Bilstein shocks. The sway bars reduce body roll and provide a nice balance when handling at the limit. UMI’s 530 lb/in front springs and 130 lb/in linear springs are precision wound from premium CrSi wire and feature medium stiffness to control body movement and reduce floating found with factory springs while still providing a comfortable ride. Bilstein gas charged shocks round out the package. Choose UMI’s Stage 1 as an excellent step to transforming your A-Body into a capable daily driver or corner carver. Every component in this kit, as with all UMI products, is Made In USA.
Springs vs. Engine weight: Small block motors, Pontiac 400 or Big Block with aluminum heads and intake tend to sit level with this kit. Lightweight LS may require spring trimming. An additional 1/4″ front end drop may occur on vehicles with full weight big block engines.
