UMI ABF401-67-1-B 67 A-Body Kit, 1 Inch Lowering Stage 1, Black

The Stage 1 is perfect for the A-Body owner who wants a simple and effective suspension upgrade with real handling improvement. This kit includes our trusted 1.250” front sway bar and 1” 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.
