The UMI front lower A‑arms for 1970–1981 Camaro and Firebird (and 1978–1996 B‑Body) relocate the lower ball joint to add 2° of caster for improved steering feel and stability. Constructed from 1.500" USA DOM tubing with chromoly cross shafts, heavy duty spring buckets and greaseable polyurethane bushings, these arms are direct bolt‑in and compatible with popular hybrid coil springs and most eyelet‑style sway bars.
