UMI's rear control arm kit for 1964–1967 GM A‑Body is a durable upgrade for street, strip or corner work, reducing suspension deflection for crisper handling and less wheel hop. The boxed lower arms feature reinforced sway bar mounting holes and CNC machined radii; upper fixed arms use a 1/4" thick laser cut mounting pad. Assembled with greaseable polyurethane bushings and finished in powder coat, the kit installs in approximately two hours.
