Powerflex Rear Diff Rear Bushings are the ideal replacement for the bushings on your E34 525i/530i/535i/540i/M5 and E32 735i/740i/750iL. Not only will these provide an improvement in performance, but they're guaranteed to last a lifetime!
These bushings are for the back of the E34/E32 differential and fit in the subframe. They must be used with the matching Powerflex front diff bushing, part #PFR5-631Bx1.
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.
This is the Powerflex Black Series diff mount. This is a much stiffer material than normal OEM rubber or standard Powerflex bushing. Additional noise, vibration, and harshness should be expected. We recommend the Black Series for track use only.
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.
