ARB Air Compressors





We stock all of the different ARB Air Compressors at JustDifferentials.com, from the compact all the way up to the dual. There are many different options for actuating your air lockers and filling tires. You can also choose between 12 and 24 volt, based on the power system you have in your vehicle. These compressors aren't just for vehicles that are equipped with ARB Air Lockers, they are useful if you need to inflate air bags, fill tires, power air horns or do just about anything else that requires onboard air.






This compact vehicle mounted Air Locker Air Activation System has been specifically designed to provide on-board air for activating ARB Air Locker locking differentials. A smaller unit, it comes with a mounting bracket that allows versatile positioning and is sealed for moisture and dust resistance with quality components used for reliable compressed air and extra long life.

So what makes this compressor special? It's small enough to fit into even the tightest space and quiet enough to mount in the cab. It has enough output to air up four 35" - 37" tires in a single duty cycle and typically airs up a 35" tire in just over two minutes. And, it works. We've tested this unit in ovens, freezers, underwater and in the silty dust of the Simpson Desert and it continues to perform.
