Upper Control Arms

The Delrin bushings add strength and eliminate the excessive deflection with stock rubber bushings. Designed for street performance, drag race, and handling, and pro-touring applications, BMR upper A-arms are engineered to provide 2 additional degrees of positive caster for increased high-speed stability. Combine with BMR Lower A-arms, and you get 4 additional degrees of positive caster over stock (2 degree from the uppers and 2 degrees from the lowers). This gives you improved geometry and increased lateral grip during cornering situations. The upper arms also have revised cross shaft geometry and shorter overall length, requiring less shim stack to achieve negative camber on lowered cars, or race and pro touring vehicles with aggressive alignments. The combination of cross shaft design and the shortened overall A-arm length gives you an improved camber curve through the front suspensions range of motion.BMR's suspension AAU462 Non-Adjustable Upper A-arms are available in black hammertone and red powdercoat for long-lasting good looks. Installation time is 2-3 hours. Proudly made in the U.S.A.

BMR A-arms stabilize your vehicle. A-arms are one of the most important, yet overlooked suspension components. They are the direct link between the front wheels and the chassis. Any deflection causes a change in alignment, which results in poor performance and driving feel. BMR Suspension A-arms are fabricated from heavy-duty 0.095 in. wall DOM tubing with laser-cut, CNC-formed plate steel for extra strength and to eliminate deflection. BMR A-arms are fitted with heavy-duty ball joints and 95-durometer polyurethane bushings for a solid, more responsive feel over the stock rubber bushings. Polyurethane adds strength and reduces deflection over the stock rubber bushings, while still absorbing much of the NVH, providing you with a great blend of performance and comfort. Designed for street performance, drag race, handling, and pro-touring applications, BMR A-arms give you improved geometry and increased lateral grip during cornering situations.
