Whether you use your 4 wheel drive once a year or daily, 4x4 Posi-Lok is the only sure thing.
4x4 Posi-Lok is a permanent replacement for the failure prone O.E. vacuum and electric front axle engagement systems. It allows you to engage the front axle from inside the cab. A one-inch pull of the cable ensures you will have 4-wheel drive when you need it, as long as the transfer case is engaged.
It is not a posi-trac or locker. It's a patented front axle engagement system that works every time because you are in control.

•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.
