Launching harder, reducing wheel hop, and adding cornering consistency to your Third or Fourth Gen GM F-body is easy with lower control arms from BMR Suspension. BMR’s polyurethane, non-adjustable tubular control arms for F-bodies are the ultimate is strength. Stock stamped steel control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. Manufactured from heavy-duty 1 5/8-inch, 0.120-inch wall steel tubing, the TCA001 polyurethane lower control arms nearly eliminate all control arm deflection. Greasable, internally fluted, 95-durometer bushings add a solid, more responsive feel over the stock rubber bushings. BMR’s 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.
