A-arms, Upper, Non-adjustable, Delrin, Std Ball Joint 2013 Ford Mustang Rear spring rates - 160A 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 braces for extra strength, deflection is eliminated with A arms from BMR Suspension.
