Polyurethane Bushing Insert

The Powerflex Road Series Rear Diff Cross Member Bush Insert acts as a stabilizer for the rear differential, limiting excessive movement that can occur with aging rubber bushings. By installing this polyurethane insert into your vehicle's factory bushing, you achieve improved control over suspension geometry, which can help address issues like premature tire wear and braking instability. The component is engineered to provide a 25-30% increase in stiffness over standard rubber without introducing additional noise, vibrations, or harshness. This product is specifically designed for 4WD models, including the Mini Countryman (R60) and Mini Paceman (R61). Note that this part is an insert designed to fit into the original OE bushing (part number 33309804479). If a full replacement bushing is required, this insert should not be used. Please verify your vehicle's specific fitment, as this part is tailored for these designated R60 and R61 configurations. Powerflex backs this Road Series component with a lifetime warranty for the original purchaser, provided it is not used in track, motorsport, or competition environments. Proper installation is critical to the warranty and performance of the part; users should follow standard chassis component installation procedures and ensure all mounting points are secure.
