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 1.25-inch, 0.095-inch wall DOM tubing with laser-cut, CNC-formed steel plate for extra strength, deflection is eliminated with A-arms from BMR's suspension. BMRs AA012 Upper A-arms are equipped with CNC machined, nickel-plated, dual-offset cross-shafts with heavy-duty stainless bushing retainers. They come pre-assembled with new polyurethane bump stops. New upper ball joints are included as well. Greaseable, 95-durometer 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 AA012 Upper A-arms eliminate deflection, greatly improving steering feel and response in normal and performance driving situations. The compact design provides additional header clearance over stock A-arms, allowing you to run larger primary tubes for high-horsepower applications. The polyurethane bushings add strength and reduce deflection over the stock rubber bushing, while still absorbing much of the NVH.
This means you get a great blend of performance and comfort. Designed for street performance, drag race, handling, and pro-touring applications, BMR upper A-arms are engineered to provide 2 additional degrees of positive caster for increased high-speed stability. These A-arms give you improved geometry and increased lateral grip during cornering situations. The upper arms also have revised cross shaft geometry, requiring less shim stack to achieve negative camber on lowered cars, or race and pro touring vehicles with aggressive alignments.BMR's suspension AA012 Non-Adjustable Upper 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.Control arm hardware kit RH007 (Includes upper and lower control arm hardware - Highly Recommended) also available.
