4x4 Posi-Lok - 4WD Engagement Systems

Welcome to 4x4 Posi-Lok
	You paid thousands of dollars for your 4-wheel drive! Shouldn’t it work when you need it? 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.

Allows you to engage the front axle from inside the cab.

Engagement every time because you are in direct control.

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.

Simple and easy to install.

A patented front axle engagement system
