Powerflex Track-Series Urethane Rear Diff Bushing Set - F10 528i/535i/550i, F06/F13 640i/650i, F02 740i/750i/750xi

Powerflex performance urethane bushings for the rear diff mounts on the F10 528i/535i/550i, F06/F12/F13 640i/650i, and F01/F02 740i/750i/750xi will reduce differential movement under loading/unloading and give a more secure and direct feel to the rear axle. Performance bushings that are stiffer than stock do not cause as much "wind-up" or deflection. Not only will these provide a noticeable improvement in performance, but they're guaranteed to last a lifetime!

This set includes all 3 bushings for the rear differential - two in the front and one in the rear of the diff.

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 set includes the black mounts designed for track use. These may be overkill for street use with almost zero deflection in the driveline.

Street / Purple - perfect as an OEM+ replacement that is slightly stiffer than the factory rubber bushing. This will have NVH levels closest to stock.
Track / Black - much stiffer than stock and nearly solid like a Delrin bushing. NVH levels will be higher than stock or Street urethane but the trade-off is that bushing deflection is almost eliminated.

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!
