UMI 2" lowering spring set for 1967–1972 GM A‑body vehicles delivers a 2" ride height reduction with consistent linear rates for improved handling. Front springs use 5160 CrSi wire at 530 lb/in and rear springs 9254 CrSi at 130 lb/in to reduce body roll and prevent the floating sensation common on A‑bodies. Built for Auto‑x, Pro‑Tour and spirited cruising, these USA‑made springs are powder coated and engineered for SBC, Pontiac 400 and many Big Block or LS installations.
