Upper Control Arms

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. Fabricated from heavy-duty 1.500-inch, 0.095-inch wall and 1.525-inch, 0.095-inch wall DOM tubing with laser-cut, CNC-formed plate steel braces for extra strength, deflection is eliminated with A-arms from BMR's suspension. BMR(TM) s AAL321 Lower A-arms are fitted with heavy-duty ball joints and greaseable, Delrin bushings add a solid, more responsive feel over the stock rubber bushings. BMR(TM) 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 reliable operation over the life of the bushings.BMR(TM) s AAL321 Lower A-arms eliminate A-arm deflection, greatly improving steering feel and response in normal and performance driving situations. The Delrin bushings add strength and eliminate deflection compared to stock rubber bushings. The tubular design gives you tons of added strength and a significant reduction in weight over the stock arms. The means you get a great blend of performance and comfort. Designed for street performance, drag race, and road course applications.BMR's suspension AAL321 Non-Adjustable Lower A-arms are available in black hammertone and red powdercoat for long-lasting good looks. Installation time is 3-4 hours. Proudly made in the U.S.A.
