BMR Suspension AA030H Upper & Lower A-Arm Kit for 1978 GMC G-Body

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 1.5-inch, 0.095-inch wall and 1.25-inch, 0.095-inch wall DOM tubing, deflection is eliminated with A-arms from BMR's suspension. BMR's AA040 Lower A-arms are equipped with greasable, 95-durometer polyurethane bushings. 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.
