UMI Performance's tubular upper and lower a-arm kit for 1970–1981 GM F-Body improves steering feel and high-speed stability by relocating both upper and lower ball joints to produce 5–7° total positive caster while leaving spindle pin location unchanged for stock fender clearance. The kit includes CrMo offset cross shafts to reduce shim needs, a polyurethane bump stop, quality ball joints, heavy-duty spring buckets for factory or hybrid coilovers, double-shear sway bar end links, and a durable red or gloss-black powder coat, made in the USA.
