Performance urethane rear diff mount for E46 non-M and E85 Z4 non-M.
Powerflex Rear Diff Rear Bushings are the ideal replacement for the bushings on your E46. Not only will these provide an improvement in performance, but they're guaranteed to last a lifetime!
Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques. Durometer is standardized per fitment and location, so you can rest assured knowing the design engineers have selected the optimal urethane hardness for this specific part.
Street Performance for slightly more sport and precision in daily driving environments. Urethane material for less deflection, more precise handling, and better response but while retaining comfort for street use. These give your BMW the performance it should have had instead of a compromise.
Street/Track is a firmer urethane material that will further reduce deflection and provide a more rigid mount. These are typically on the edge of street-ability; firmer bushings will have more noise and vibration than a rubber or the Purple urethane but still acceptable for most for normal street use. For true racing or track use you would look for a Delrin or aluminum mount.
Note: Powerflex copper-based grease is supplied with every bushing set, and they will rarely need re-lubing due to the unique design features built into the material to hold the lubricant.
Lifetime warranty.
