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.
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.

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.

The wiring diagram and instructions are simple and easy to assist if modifying the harness length for your application. Definitely go with the One-Off Fabrication's master cylinder mount if attaching to a Jeep JK.

Good things come in small packages
The Compressor is small but mighty. It did everything it said it would. It took about 2 minutes to fill my tires from 15 lbs to 40 lbs not bad for a little guy. It should come with some rubber grommets to reduce vibration. I bought some at the local hardware store.

Works great. Will use often

two minutes to fill from 15 psi to 32 psi on 33" tire.

Fast little unit
I had the low vol ARB on a previous truck. This one is much faster. As fast as my worn out 3/4hp blojax. Use high temp 3/8" fuel line on the output. Ordinary air line will melt. Try to keep it away from heat.

Very nice work
Make it smooth ride

Just as Advertised
Installed in a 2007 Toyota Tacoma. Easy to install and having the wiring harness make the job a snap. Is a little slow to fill but for the size I did not expect any better. Be careful the pump and any fittings attached to the pump get very hot after a few minutes of continuous operation.
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?
Chris from Dallas on
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.

Can i use the Heavy-Duty Air Compressor along ARBCKMA12 with my AirLift LOAD LIFTER 5000 Air Bags AIR88230? Can yo please send me any literature.
Armando from La Puente, CA on
Yes, the ARB 4x4 Accessories Heavy-duty Air Compressor for ARB Air Lockers ARBCKMA12 will work with the AirLift LOAD LIFTER 5000 Air Bags AIR88230. Thank you.

How well does this compressor work with filling tires? Does it get hot? And how amps does it draw?
Mikey from on
It will pump up tires but is rather slow if you need to do all four. Yes all compressors do get hot right at the compressor head. That is why most have a short steel braided line off the head like on the Viair. If you are looking for a compressor for mainly doing tires I would look for a larger compressor.
