Launching harder, reducing wheel hop, and adding cornering consistency to your 1978-1987 GM G-body is easy with adjustable upper control arms from BMR Suspension. The stock control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMRs polyurethane, on-car adjustable tubular upper control arm for G-bodies (UTCA055) are manufactured from heavy-duty 1 1/4 inch DOM steel tube. The center adjuster is CNC-machined from chrome-moly steel with rolled threads for the ultimate in strength and durability. This design gives you a strong control arm that greatly improves performance. Greasable, internally fluted, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMRs bushing design allows grease to evenly coat the inner sleeve, keeping grease in the bushing under high loads. These flutes also direct grease to the outer edge of the bushing, keeping the thrust surface lubricated. This efficient lubrication ensures quiet, reliable operation over the life of the bushings.
