Reduce cradle bushing deflection and minimize wheel hop 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 than soft rubber. It doesn’t break down from exposure to petroleum products, road salt, ozone, and other elements of the harsh undercarriage environment suspension bushings live in. BMR’s polyurethane cradle bushing inserts (BK040) 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, and absorbs road noise and engine vibrations. This allows you to increase performance without decreasing comfort. bmrbk040

Designed for street performance applications, BMR cradle inserts bushings enhance the rear stability of the vehicle by minimizing cradle movement. This provides a much more stabilized and predictable platform that permits the suspension to do its job. The OE bushings are designed with air pockets in soft rubber bushings. Rather than replace the entire bushings, the BMR cradle inserts bushings fill these voids, limiting the inherent movement of the factory design. There is no discernible increase in ride quality or noise level with this modification. bmrbk040
