Reduce cradle bushing deflection and minimize wheelhop with polyurethane cradle bushing inserts 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 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 cradle bushing inserts (BK016) drastically increase cradle stability over the factory rubber bushings. The bushing inserts are molded from 95-durometer polyurethane, which reduced bushing deflection by filling the large voids in the factory bushings. 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.
