An advanced helical aftermarket LSD for late model BMWs. Finally an LSD for your E46, E60, E8x or E9x which is affordable. This is a quiet, predictable and cost-effective LSD featuring advanced technology and materials. 

This is a new MFactory LSD to fit late model 6 cylinder vehicles with the mid-case 188k diff. This LSD features large oil passages which deliver around double the oil flow of even the M3 LSD. This LSD features:

  • Made from Japanese SAE 4320 steel
  • Forged, tempered and sub-zero treated
  • Low pre-load for chatter-free performance
  • Helical torque biasing

The technology inside, and the quality of the materials are exceptional.

A very significant improvement in cornering speed and general performance. A must-have for track-day cars, club racers and enthusiasts. We also sell gear sets, clutch kits and LSD rebuild kits.


To install this LSD, you will require a 188k shim kit. You cannot set the pre-load and backlash properly without it.
