BMW 188 LSD, E36 etc.

Nordic R-Tec BMW 188 differential lock, Torsen lock, helical gear lock.

The Torsen LSD lock works with helical gears which transfer traction to the more grippy wheel. The structure also makes it really durable.

If traction is 0, i.e. the wheel is in the air, then the power is not transmitted but needs a small torque, e.g. by helping with the brake.

Fits the following models 188 rear (drive shaft flanges with 6 bolts).
