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 plate, deflection is eliminated with A-arms from BMR Suspension. BMRs AA004 Upper A-arms come with new upper ball joints and heavy-duty rod ends, which add a solid, more responsive feel over the stock rubber bushings. BMRs uses zinc-plated, X-series, heat-treated, chrome-moly, self-lubricating, Teflon-lined rod ends, giving you the ultimate is strength and reliability.BMRs AA004 Upper A-arms reduce weight and eliminate upper A-arm deflection, greatly improving steering feel and response in normal and performance driving situations.
