Frequently asked questions

How do I know which locker fits my vehicle?

By axle type and axle shaft spline count, and for some axles also by the ring and pinion ratio. The model year alone is not enough – the same model was built with different axles.

Do I need an air compressor?

Yes. An Air Locker runs on compressed air, so a compressor and a switch kit are required.
