Eaton Suretrac limited slip differential
The Suretrac performs like an open differential under "normal" conditions, and automatically transfers torque to the wheel with better traction when conditions warrant. The Suretrac limited slip differential responds instantly to torque feedback, anytime, at any speed. Suretrac reduces one wheel spin-outs from disabling the vehicle and also limits shock loads on drive train components to extend their life.
Suretrac transfers torque flow by combining conventional type differential components with additional friction packs. The special coated friction plates react to movement between the gears and the differential case. The wheel with the least traction is locked and power is transferred to the wheel that has the best traction.
