NOTE: This product is designed for cars with the bump stops installed on the front side of the lower A-arm. See additional information below.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 1.625-inch, 0.120-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. BMRs AAL311 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. BMRs 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.BMRs AAL311 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 reduce deflection over the stock rubber bushing. Designed for street performance, drag race, and handling, and pro-touring applications.
