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, 0.120-inch wall DOM tubing, deflection is eliminated with A-arms from BMR Suspension. BMR's AA750 Lower A-arms are equipped with greasable heavy-duty ball joints, 95-durometer polyurethane bushings (front mount), and greasable Delrin bushings (rear mount) to handle the high loads. Polyurethane 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 quiet, reliable operation over the life of the bushings. The combination of poly and Delrin bushings gives you improved steering feel and responsiveness for any for of driving.
