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 Suspension. BMR’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’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.
