4x4 Posi-Lok developed a differential locking system that replaces the vacuum 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 connects the right front axle to the intermediate shaft using the shift collar and fork, and 4-wheel drive is engaged!
Replace your old fading vacuum shift motor with the rugged 4x4 Posi-Lok. The 4x4 Posi-Lok is a driver operated manual cable system that replaces the failure prone vacuum engagement system.
When installing a 4x4 Posi-Lok system, we recommend that you also replace the shift fork inside the axle housing.
