Launching harder, reducing wheel hop, and correcting rear suspension geometry on your lowered 2015-newer S550 Mustangs is easy with adjustable upper control arms from BMR Suspension. Stock upper control arms with soft rubber bushings deflect under load and absorb power instead of transferring it to the tires. The factory arms also don’t allow for proper camber correction on lowered vehicles. BMR’s Delrin, adjustable control arms for Mustangs (UCA763) are CNC-machined from 6061-T6 billet aluminum This design gives you an incredibly strong control arm that greatly improves performance. Greasable, solid Delrin bushings add a solid, more responsive feel over the stock rubber bushings. BMR’s bushings are internally fluted, which allows grease to evenly coat the inner sleeve. 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. The UCA763 also features zinc-plated two-piece, X-series, heat-treated, chrome-moly, self-lubricating, Teflon-lined rod ends. It also features 304 stainless steel, custom designed rod end spacers. This design provides reduced deflection, increased articulation, and an all-around improvement in performance BMR Suspension designed the UCA763 to work well in street performance, drag race, and road race applications. The stock control arm bushings deflect under cornering loads giving you inconsistent handling characteristics. BMR’s Delrin bushings are designed to eliminate deflection, while being able to stand up to high loads of any performance environment. The UCA763’s heavy-duty construction and strong solid Delrin bushings give you much improved repeatability on the street, starting line, or in the corners. The UCA763s are primarily designed for lowered cars that are looking to remove the negative camber gained from lowering the cars. These arms are adjustable and give you the ability to correct the camber setting on lowered S550s. ALL cars will benefit from these adjustable upper control arms. These are the perfect upgrade for the enthusiast looking to improve performance at an affordable price, while maintaining acceptable NVH levels and ride quality. When performance is a must, rely on BMR Suspension! BMR Suspension’s UCA763 adjustable polyurethane upper control arms are available in a durable black anodized finished for long-lasting good looks. Installation time is about 3 hour. Proudly made in the U.S.A.
