universal fit logo



The ARB Air Compressor is an integral component of the air locker system. The ARB Compressor Kit is designed to operate single as well as a dual (front and rear) locker system. Not only will it enable the ARB lockers to work but it is also capable of supplying air pressure for other occasions, such as refilling a low tire. This air compressor features a die cast aluminum storage tank, oil-less operation and the highest air delivery capacity of all the mid-price range compressors (100 psi) setting on cut off switch. The ARB Air Compressor Kit contains a pre-assembled compressor, mounting clamp, backing plate, pressure switch, wire loom and all the mounting hardware. Current draw of 9 amps during no load, 20 amps for full load.

5.0 Small package, big bang

Great air output for such a small compressor. Highly recommended.

5.0 Nice kit

This compressor part number comes with a wiring harness for the compressor and two lockers from battery to compressor to dashboard. The lockers come with their own switches and valves. The major parts of the compressor can be rotated about the axis of the motor to allow easier configuration for the space available. Everything seems substantially made, heavy, well labelled, and good directions.

5.0 Purchased for airing up tires

Having a very small 4x4 this compressor inflates my tires extremely fast. Guessing approx 15-30 sec/tire from 26 psi for fast off road driving to 40psi for hwy driving. I have very small volume tires compared to most 4x4's however. We have the same compressor on our work vehicles and it will do a 265/75-16 in approx 2-3 min/per tire from 15 psi to 36 psi. If you have a larger vehicle that requires higher pressures and have larger tires I would recommend the dual compressor if you have the budget for it. This compressor could still do it w/o any problems I'm sure, it would just take awhile to get say a 285/75-16 up to 80 psi from 15 psi for example. This is still very very much faster than any cigarette lighter operated compressor and you won't regret getting it.

Q: Can i run this to a 2.5 gallon air tank as well as use it for a front ARB locker? Answer this question

A: Yes, but we recommend using a manifold kit (Part# 171503) with it, so you can output the air separately to the locker and the air tank.

Q: According to ARB this compressor has a 50% duty cycle (30 min on, 30 min off). Is that automatically controlled, or does the user have to comply with the duty cycle rating? If I left the switch on would the compressor cycle on/off to prevent damage? Answer this question

A: Hello It depends on what you are using it for. If you are running ARB air lockers it will cycle on its own every few minutes. There is also a pressure switch that turns it on and off at maximum PSI. Thanks
