Product Details

This is complete rebuild replacement for your factory differential. The rebuild starts with replacing all seals and bearings, then the M Variable LSD unit is completely rebuilt using all new components, and then finally the factory 3.62 gearing is replaced with a BMW Motorsport 3.91 rear gear for quicker acceleration. 

The 3.91 gearing is the recommended gear set for SMG equipped cars, for 6 speed cars we recommend the 4.10 rear gearing (ES3184280).
