Product Overview

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 plate steel braces for extra strength, deflection is eliminated with A-arms from BMR Suspension. BMR(TM) s AAK321 Upper and Lower 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, and new upper ball joints are included. Upgraded 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 quiet, reliable operation over the life of the bushings.
