BMR 78-87 GM G-Body Non-Adjustable Upper A-Arms Delrin Std Ball Joint - Red - AAU461R

Combine with BMR Lower A-arms, and you get 4 additional degrees of positive caster over stock (2 degree from the uppers and 2 degrees from the lowers). This gives you improved geometry and increased lateral grip during cornering situations. 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's suspension AAU461 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.
