- 4x4 Posi-Lok will not disengage when ignition is turned off or the differential is submerged.
Overview
4x4 Posi-Lok replaces stock 4WD actuators, allowing front axle engagement control from inside the cab. After engaging the transfer case, a quick 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. Works with lockers - when the front axle is locked, simply disengage the passenger side in order to make turns without wheel hop.
