4x4 Posi-Lok replaces the thermal linear actuator with a cable operated actuator that puts the driver in control of the engagement from inside the cab. After engaging the transfer case, a one inch pull of the 4x4 Posi-Lok cable slides the shift fork and collar to connect the right front axle to the intermediate shaft and 4-wheel drive is engaged! Simply reverse the procedure to disengage 4-wheel drive. 4x4 Posi-Lok also works great with lockers! When the front axle is locked, you can disengage the passenger side in order to make turns without wheel hop.
