After 3D scanning a lot of gearboxes we found that almost every gearbox had its own dimensions. Different bore sizes, mounting bolt size, hole of sets, no hole ofset. Not sure what the ZF engineers been up to be honest.

So we ended up with three different designs, all verified on the following gearboxes so far
8HP45 N54/N55
8HP70 N57
8HP75 N57 X5 X6
8HP70 N63
8HP75 B57
8HP90 N73/N74

Most probably they fit any other BMW 8HP gearbox as well, just send us a message and we will help you out.
