Launching harder, reducing wheel hop, and adding cornering consistency to your 1978-1987 GM G-body is easy with upper control arms from BMR Suspension. Stock control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR?s
polyurethane, on-car adjustable tubular control arms for G-bodies (UTCA007) are manufactured from heavy-duty 1 5/8 inch, 0.120-inch wall DOM steel tubing. The center adjuster is CNC-machined from chrome-moly steel with rolled threads for the ultimate in strength and durability. The arms feature TIG-welded chrome-moly tube adapters. This design gives you a strong control arm that greatly improves performance. Two-inch greasable, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMR?s bushings are internally fluted, which keeps grease in the bushing, even under heavy load. 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.
