1968-1972 Chevrolet UMI Stage 1 Handling Package, 1 Inch Lowering, Black

Product May Vary From Above Listed Image

The Stage 1 is perfect for the Chevrolet owner who wants a simple and effective suspension upgrade with real handling improvement. This kit includes our trusted 1.250 inch front sway bar and 1 inch rear sway bar combined with performance lowering springs and UMI monotube 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 while still providing a comfortable ride. The UMI monotube shocks feature a large diameter piston and nitrogen charge to dampen bumps and provide a crisp feel without being harsh. The shock is configured with heavy-duty mounts to ensure durability and fits in the stock location. Choose UMI's Stage 1 as a 1st 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.
