Reduce cradle and differential bushing deflection and minimize wheelhop with Rear Cradle Bushing Kit from BMR Suspension. Polyurethane is a synthetic polymer that has many properties that make it far superior to the rubber used in OEM bushings. Polyurethane deflects far less that soft rubber, and it doesn’t breakdown from exposure to petroleum products, road salt, ozone, and other elements of the harsh undercar environment suspension bushings live in. BMR’s polyurethane Rear Cradle Bushing Kit (BK003) drastically increase cradle and differential stability over the factory rubber bushings. The cradle bushing inserts (BK002) are molded from 95-durometer polyurethane, which reduced bushing deflection by filling the large voids in the factory bushings. He polyurethane differential bushings (BK001) are molded from 68-durometer polyurethane, which reduced bushing deflection, while still absorbed road noise and engine vibrations. This design reduces deflection and improves the overall feel of the car, while still absorbed road noise and engine vibrations. This allows you to increase performance without decreasing comfort. Designed for street performance applications, BMR cradle and differential bushings minimize wheel-hop and reduce rear cradle movement in your Pontiac G8. The kit includes bushings for the rear differential (BK001) and suspension cradle (BK002). The BMR Rear Cradle Bushing Kit (BK003) minimizes movement and provides additional rigidity in these critical areas, which ensures maximum power transmission to the wheels. This results in better handling and more consistent launches without significantly increasing noise, vibration, or harmonics. BMR Suspension’s BK003 Busing Kit is available in black. Installation time is about 5-6 hours and may vary depending on stock bushing removal technique. Proudly made in the U.S.A.!
