Why 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.

What is 4x4 Posi-Lok?




After installing my Posi-Lok engagement system on my 1987 Dodge Ramcharger, I’ve enjoyed trouble-free 4x4 capabilities. I thought this photo of the sticker on my rear driver’s window represents your product well…in true form!
