Quick Overview

4x4 Posi-Lok offers a cable operated shift actuator that features new cast aluminum housing for the central axle, heavy duty cable and complete wiring system to ensure the 4WD dash indicator light functions properly.

Put yourself in control of the engagement from inside the cab with the 4x4 Posi-Lok cable operated actuator. When the transfer case is engaged, 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. To disengage 4-wheel drive, simply reverse the procedure. 4x4 Posi-Lok also works great with lockers! You can disengage the passenger side when the front axle is locked in order to make turns without experiencing wheel hop.

  • 4x4 Posi-Lok reduces front differential wear and right axle breakage.
  • 4x4 Posi-Lok provides 2-wheel drive low range, giving the vehicle 4-LO torque at the rear axle with bind free steering only available in 2-HI. This feature is not available with factory systems and is beneficial when maneuvering trailers.
  • 4x4 Posi-Lok will not disengage when ignition is turned off or the differential is submerged.
  • 4x4 Posi-Lok is compatible with manual or electric transfer cases and installation can be completed in one to two hours with basic hand tools. No internal differential work is required.
