TC101B-TYTA1 - LSD Specs:
1.5 Way Multiple Plate Clutch LSD
The Technical Trax LSD unit is based on the multiple plate clutch design. With this design the multiple friction clutch plates are located between the side gears and the differential casing and utilize the pinion and cam gears. This is a torque proportional type LSD. In the usual differential arrangement it is connected to both left & right axles directly, when the driving force of one side differs in speed the pinion gear with the cam angle forces the clutch plates to compress and grip to in effect transfer the driving torque evenly to both axles. The T-TRAX ADVANCE has adopted this system which has proven its effectiveness as the best for 2WD applications.
