The UMI front lowering spring for 1978–1988 GM G‑Body applications drops ride height about 2" while tightening roll control for corner carving and cruising. Wound from 5160 CrSi premium wire with a linear 600 lb/in front rate, these springs are stiffer than stock to reduce body roll and floating. Finished in tough black powder coat and made in the USA; lightened cars or V6 Turbo Grand National applications may require trimming.
