The patented Hydratrak limited-slip differential provides improved handling and enhanced safety for drivers by incorporating a cartridge-type fluid coupling, which progressively and smoothly increases torque transfer to the wheel with traction.

Thus, the more one wheel slips, the more useful traction that is transferred to the opposing wheel.
