The upper arms also have revised cross shaft geometry and shorter overall length, requiring less shim stack to achieve negative camber on lowered cars, or race and pro touring vehicles with aggressive alignments. The combination of cross shaft design and the shortened overall A-arm length gives you an improved camber curve through the front suspensions range of motion.BMR Suspension AAU401 Non-Adjustable Upper A-arms are available in black hammertone and red powdercoat for long-lasting good looks. Installation time is 3-4 hours. Proudly made in the U.S.A.
BMR AAU401 upper A-arms eliminate deflection, greatly improving steering feel and response in normal and performance driving situations.
