BMR Suspension A-Arms

BMR A-arms stabilize your vehicle. 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. BMR Suspension A-arms are fabricated from heavy-duty 0.095 in. wall DOM tubing with laser-cut, CNC-formed plate steel for extra strength and to eliminate deflection. BMR A-arms are fitted with heavy-duty ball joints and 95-durometer polyurethane bushings for a solid, more responsive feel over the stock rubber bushings. Polyurethane adds strength and reduces deflection over the stock rubber bushings, while still absorbing much of the NVH, providing you with a great blend of performance and comfort. Designed for street performance, drag race, handling, and pro-touring applications, BMR A-arms give you improved geometry and increased lateral grip during cornering situations.
