Question

DIFFERENTIAL | LOCKER - What is the difference between a locker and a limited-slip differential?

Accepted Answer

Lockers produce 100% lock-up where all the power is directed to both tires all the time when the unit is engaged. Lockers are tougher. Limited slips direct torque to both tires and when slippage occurs the unit directs torque to the tire with the best traction. LSDs do not generate 100% lock-up. Limited-slip diffs do not require activation from the driver. Their engagement is mechanical, a reaction to driving conditions, namely load and wheel slippage.
