Launching harder, reducing wheel hop, and adding cornering consistency to your 2011-2014 Ford Mustang is easy with an upper control arm from BMR Suspension. The stock control arm 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 arm for S197 Mustangs (UTCA030) is manufactured from heavy-duty 1 5/8 inch, 0.120-inch wall 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.
