Since March, 2007 production, BMW has fitted rear axles where the ring gear is welded to the differential carrier.

Our Install Kits, combined with precision machinework, allow fitment of a Wavetrac® differential in late-model BMW rear axles where the ring gear is factory welded to the standard differential.

• Wavetrac® Differential
• Customer’s machined ring gear
• Precision-ground spacer ring (where required)
• Set (10) of custom, high strength ARP® ring gear bolts

For the best possible performance, disassembly of the stock axle, and fitment of the Wavetrac and Install Kit should be performed by one of our Specialist Dealers. This ensures that the condition of the axle can be assessed before modifications are performed, and that the re-assembly is done professionally – ensuring correct gear backlash and bearing end play.
