4K Ultra HD Resolution Desktop Wallpapers Top Free 4K Ultra HD BMR 67 69 1st Gen F Body Non Adj. Upper A Arms (Polyurethane) Red. The polyurethane bushings add strength and reduce deflection over the stock rubber bushing, while still absorbing much of the NVH. The means you get a great blend of performance and comfort. Designed for street performance, drag race, and handling, and pro touring applications, BMR upper A arms are engineered to provide 2 additional degrees of positive caster for increased high speed stability. Combine with BMR Lower A arms, and you get 4 additional degrees of positive caster (2 degree from the uppers and 2 degrees from the lowers), providing up to 6 degrees of total positive caster over stock. 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 a improved camber curve through the front suspensions range of motion. BMR's suspension AA005 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. Control arm hardware kit RH006 (Includes upper and lower control arm hardware Highly Recommended) also available.
