UMI’s lowering package includes four Viking double adjustable shocks, a hybrid front coil-over spring system with 450 lb front springs, and your choice of 1 or 2-inch UMI rear lowering springs. The 450 lb springs are recommended for small block cruising and big block drag racing, providing a firmer ride for improved handling and performance. The hybrid front coil-over system allows a 0–3" adjustable front drop, while the rear springs offer 1" or 2" lowering options to achieve the desired stance. Viking’s double adjustable shocks feature 19 compression and 19 rebound settings, enabling easy, tool-free tuning for street, strip, or corner-carving performance. The kit is fully bolt-in, requiring no welding or front spring compressor, and optional Spanner Wrench and Thrust Bearing Kits simplify height adjustments. This setup delivers a strong balance of ride quality and performance for both street and drag applications.
