What is a Zip Locker and how does it work?

A Zip Locker is an air-operated differential that allows you to switch between an open differential for normal driving and a 100% locked state for maximum traction. It uses compressed air to engage a locking mechanism within the differential.

What else do I need to install and operate this locker?

To operate this air locker, you will need an air compressor capable of supplying sufficient air pressure and an activation switch. You will also need to ensure you have the correct air line routing and any necessary fittings for your specific vehicle setup.

Is this locker compatible with all Ford 10.25" and 10.5" axles?

No, this locker is specifically designed for full-float axle applications only. It will not fit semi-float axle configurations. It's important to verify your axle type before purchasing.
