Enhance the stability of your Pontiac G8 with a Rear Inner Upper Control Arm Bushing Kit from BMR Suspension. Polyurethane is a synthetic polymer that has many properties that make it far superior to OEM rubber bushings. Polyurethane deflects far less that soft rubber, and it doesnt breakdown from exposure to petroleum products, road salt, ozone, and other elements of the harsh undercar environment suspension bushings live in. BMRs polyurethane Rear Inner Upper Control Arm Bushing Kit (BK005) drastically increases stability over the factory rubber bushings, which do little for performance. BMR designed its bushing kit from 95-durometer polyurethane. This material offers huge reductions in deflection without excessive increases in NVH. Each bushing is manufactured to strict tolerances, using exact molds, which are designed by BMR. This allows for a perfect fit and increased performance for any driving style. Designed for street performance, drag race, and handling applications, BMR Suspension BK005 Rear Inner Upper Control Arm Bushing Kit is the perfect solution for any G8 being used for performance driving. This kit offers huge increases in performance over the stock rubber bushings. The OE bushings are made from soft rubber, producing excessive bushing deflection during aggressive maneuvering. BMRs polyurethane bushings replace the OE rubber upper control arm bushings, eliminating almost all bushing deflection. This increases handling stability, and cornering ability, while giving you a much-improved overall feel in any performance driving situation. The reduction in deflection also drastically reduces wheel hop, caused by excessive bushing deflection. BMR Suspensions BK005 Rear Inner Upper Control Arm Bushing Kit is available in red with zinc-coated hardware. Installation time is about 2-3 hours and may vary depending on stock bushing removal technique. Proudly made in the U.S.A.!
