Description

The 4X4 Posi-Lok PSL400 replaces the vacuum Central Axle Disconnect (CAD) system with a cable-operated actuator, allowing driver control of 4WD engagement from the cab. A one-inch pull engages the right front axle. It also works with front lockers, enabling passenger side axle disengagement to prevent wheel hop during turns.
