UMI’s lowering package includes four Viking double adjustable shocks, a hybrid front coil-over spring system with 550 lb front springs, and your choice of 1 or 2-inch UMI rear lowering springs. The 550 lb springs are ideal for small block handling and all big block applications except for drag racing, providing a firm, performance-oriented ride with excellent control. The hybrid front coil-over system allows a 0–3" adjustable front drop, while the rear springs offer 1" or 2" lowering options to fine-tune stance and appearance. Viking’s double adjustable shocks provide 19 compression and 19 rebound settings, allowing quick, tool-free adjustments for street, strip, or precise cornering performance. The kit is fully bolt-in, requiring no welding or front spring compressor, and optional Spanner Wrench and Thrust Bearing Kits make height adjustments easier. This setup delivers maximum handling and stability for high-performance street and track vehicles.
