UMI 1" lowering spring set for 1967–1972 GM A‑body vehicles provides modern handling with a 1" drop while maintaining a comfortable ride. Front springs are wound from 5160 CrSi wire at a linear 530 lb/in rate; rear springs use 9254 CrSi wire at 130 lb/in to reduce body roll and eliminate the common "floating" feel. Engineered for standard SBC, Pontiac 400 and many Big Block or LS combinations, these springs are powder coated and made in the USA for Auto‑x, Pro‑Tour and street use.
