Launching harder, reducing wheel hop, and adding cornering consistency to your 1964-1972 GM A-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 (TCA034) are manufactured from heavy-duty 1½ 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.
BMR Suspension designed the TCA034 to work well in street performance, drag race, and road race applications. The stock control arms flex under even light cornering loads giving you inconsistent handling characteristics. Combine this with soft bushings that have massive amounts of deflection and you’re left with poor performance. The TCA034’s heavy-duty construction eliminates control arm flex, giving you much improved repeatability on the street, starting line, or in the corners. BMR’s polyurethane bushings are designed to be compliant enough to give you a comfortable ride and absorb NVH, while remaining firm enough to stand up to high loads of any performance environment. The bushings easily handle the high compression loads of hard launches and hard acceleration, yet offer plenty of articulation for great handling. The TCA034s also retain the factory sway bar mounts, so no special sway bars or brackets are required. These are the perfect upgrade for the enthusiast looking to improve performance, while maintaining acceptable NVH levels and ride quality.
BMR Suspension’s TCA034 non-adjustable polyurethane lower control arms are available in red and black hammertone powdercoat for long-lasting good looks. Installation time is about 1-2 hours. Retail pricing is set at just under $160.
