UMI tubular lower control arms for 1978–1988 G-Body cars combine a Roto-Joint on the axle side with a polyurethane bushing on the chassis side for a street-friendly, low-noise setup that still allows bind-free articulation. Constructed from 1.500" x 0.120" DOM tubing with reinforced sway bar provisions and greaseable joints, these arms ship fully assembled, use OEM hardware and are TIG welded with a durable powder coat finish.
