This helical-gear limited-slip differential uses parallel-axis planetary gears to divide torque automatically and smoothly between both wheels, with power transfer typically unnoticed by the driver. Under normal driving it behaves like an open differential; on wet, icy, or loose surfaces it automatically shifts power to the wheel with the most traction.
