Launching harder, reducing wheel hop, and adding cornering consistency to your 1978-1987 GM G-body is easy with lower control arms from BMR Suspension. Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. BMR?s polyurethane, non-adjustable tubular control arms for A-bodies (TCA039) are manufactured from heavy-duty 1? inch DOM steel tubing. 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.
