The ARB Air Locker RD168 is an air operated locking differential for the Dana 60HD,C-clip,35 SPL,4.56 & UP axle. An Air Locker is matched to the axle, not to the car model, so axle type, axle shaft spline count and ring & pinion ratio decide which model fits. The list below comes straight from the ARB application chart.

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.
