BMR 93-02 F-Body Adj. Lower A-Arms Poly/Rod End Combo - RedA 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's suspension.
