Fits: 1979–1993 Ford Mustang BMR SuspensionAA039HControl ArmsA-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. Tall ball joints are used for improved geometry and handling. 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 Suspension. BMR?s AA039 Lower A-arms are equipped with heavy-duty, Teflon-lined rod ends. BMR?s heavy-duty rod ends are designed to solidly link the A-arms to the body, eliminating deflection. Our rod ends will stand up to high loads of any performance environment, offering all of the bind-free suspension articulation needed for great handling.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.
