  • E39 3.0d 5speed (1998-2000)
  • E46 3.0d 5 speed (1999-2005)
  • E46 2.0d 5 speed (2001-2005)

These boxes are proven to be bullet proof and have been seen on applications up to 1500 nm. These boxes in good condition allow really fast shifting.

Adapter kit is ABC Clutch designed, manufactured and tested. All parts are CNC machined, checked and treated against corrosion. All measurements are taken with CNC dial-up gauge from OEM Toyota/BMW/Tilton parts for proper engine and gear box center collinear alignment fitting.

There are many adapter plates on the market, but ABCs are the only ones with centering pins, to get crankshaft center and gearbox input shaft aligned precisely. This guarantees that the multi disk clutch spline won’t be damaged caused by incorrect alignment. This is the same problem with Cut and Welded bell housings which during the welding will warp causing the misalignment.
