4x4 Posi-Lok System - Ford F150 1997-2003

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! No more waiting (& hoping) for the 4WD to engage while you slide backward down the hill! You simply reverse the procedure (push the knob back in) 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.


Easy 1-2 hour installing with common hand tools.
