Powerflex PFF5-4631 Poly Bush Upgrade for BMW E63 E64 M6

Transform the way your BMW changes gear with the Powerflex PFF5-4631 oval front bush for the change lever arm. This uprated polyurethane insert tightens up the transmission linkage, cutting out slack and restoring crisp, positive gear selection on the E63 and E64 M6. Whether you are refreshing tired factory rubber or chasing a more connected drive on fast road or track, this is a simple, proven upgrade that makes a big difference.

We have fitted this part at MJ Modifications and customer feedback has been outstanding. Expect a more precise shift action, reduced play in the selector mechanism and consistency that lasts mile after mile thanks to durable PU construction that resists oil, heat and wear far better than ageing OEM rubber.
