Reviews for ARB On Board Twin Air Compressor Kit

Highly recommended

Gift

I have two of these, and they work great.

I love this thing. I installed it in a 2019 JL 2-door using the M.O.R.E. mounting plate. (It is to the left of the back seat just below the side window and is not in the way there.) Be sure to watch the U-tube video on mounting this in a JL 4-door with the MORE mount. Most of the video is about setting up the wiring harness. The wiring harness is intended for installation of the compressor in the engine bay and for use with ARB air lockers. If you have a JL with the auxilliary switches option, strip everything but the purple wire out of the harness that connects to the ARB switch. The purple wire (don't cut it short) will reach to the aux switch connectors at the front of the passenger footwell. I ran 4-gauge battery wires from both pos and neg terminals of the battery back to the MORE mount. Then the two red wires connect to together to the red battery cable and the three black (or black with white stripe) connect to the black one. Configure the aux switch to: (1) latch, (2) ignition, and (3) not remember its setting. This way, the engine is running (presumably, at least the ignition is on), so the 80-amp (max) load comes from the altermator. (Run on the battery only, the voltage falls, so more current is needed, and then the motors can overheat.) Also, the compressor won't start when you turn on the ignition after having bumped the aux switch while the jeep was turned off.
One annoyance: this should come with a socket for your tire inflation hose. To get theirs, you have to buy the ARB inflation kit. It is a nice one, and is a female socket so there is not a male connector sticking out (which would be a hazard if you fell against the compressor). Another annoyance: plan on spending an hour trying to peel off the adhesive tape they used to bundle the wiring.

Great product and an easy and efficient way to quickly air up. I have one in each of my JKU's; one under-hood mounted and the other under the passenger seat. Each way was a pretty simple install. It's worth the price (every cent) and I would definitely recommend to anyone.

Excellent air compressor. Easy to install with the Mountain Off-Road mount.

Great product. Wiring overly complicated for alternate applications. Main power wires JUST long enough to for under-seat mount in JK; ideally needs to be 2-3" longer (will need to mod later). If using without air lockers AND some type of switch pod, the only other wire needed to run is the PURPLE wire to your switch pod from the compressor.

I think it's a good kit, my only problem is that I only wanted to use it to be able to inflate my wheels.

In this case it is necessary to modify a lot the wiring (almost all the wiring has to be redone by taking only some elements) and strictly no instructions are put by ARB in this kit to do it.

Fortunately, on forums, and YouTube, there are explanations to do it with different variants. Thanks to those who think of others :-)

Great onboard compressor. I made my own mounts and hooked it up to a 1 gallon air tank. I can fill up my stock Jeep tires in under 10 min. And. That includes getting the air hose out and putting away. The only reason I gave 4 stars I’d the wire harness. If I was putting dual air lockers on it would have been great. But I just wanted to air up the tires, so I had to cut the harness apart to make it work, and there weren’t instruction for that. Luckily I am mechanically and electrically inclined and had little trouble doing so. But all in all it was a fun project and I’m glad I did it.

I purchased mine from a local shop. Not really impressed. If I had to do it all over again, I would put up with refilling a tank or get York OBA. I had York OBA on my TJ and that was the best medication on my Jeep.
