How does the ARB Air Locker work?

When activated by a switch, compressed air locks the internal gears of the differential. This forces both axle shafts to rotate at the same speed, providing maximum traction. When unlocked, it functions like a standard open differential.

What gear ratio is this Air Locker designed for?

This ARB Air Locker RD164 is designed for Dana 60 differentials with a 4.56 gear ratio or any numerically lower ratio (e.g., 4.10, 3.73).

Does this Air Locker come with the air compressor and switch?

The ARB Air Locker itself is the differential locking mechanism. You will need to purchase a compatible ARB air compressor and activation switch separately to operate it.
