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 and 1 5/8-inch, 0.120-inch wall tubing with laser-cut, CNC-formed plate steel plate, deflection is eliminated with A-arms from BMR Suspension. BMRs AA020 Lower A-arms are equipped with greasable heavy-duty ball joints, zinc-plated, X-series, heat-treated, chrome-moly, self-lubricating, Teflon-lined rod ends and greasable, 95-durometer polyurethane bushings. Polyurethane 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. The combination of rod ends and bushings gives you improved steering feel and responsiveness, with all the adjustability needed for any for of driving. The AA020s also features a 1-inch lower shock mount for improves shock travel on lowered Fourth Gens.
