ARB INFLATION3 Twin High Performance Air Compressor CKMTA12 and Extension Hardware for Easy Installation and Connection in a New Printed Box, Ideal for Lockers, Horns, Tire Inflation and Air Tools

Absolutely needed for all Overlanding adventures. I have taken the ARB system beyond what they recommend and it keeps on giving. I 1000% recommend for all wheelers!

This product set was a little bit pricey, but ended up getting it and I am glad I did. It was not too difficult of an install at all. Product seems like great quality as well as the parts. The actual compressor was a bit heavy in hands, but fit under hood perfectly. I love the convenience of the product as well as the time it takes to inflate my tires.

Ordered this from a warehouse deal as new in original box. Even had the inspection sticker on it from Amazon that it was all there. Parts were missing (air filters, switch, brackets, the instructions, and wire harness was cut and spliced, scratches all over the compressor). Needless to say it wasnt in like new condition and had been Installed and then thrown back in the box. I know its not ARBs fault but come on Amazon, do a thorough inspection before you put it back on the shelf. The person that bought it before me basically stole a bunch of parts and through it back in there. The only reason for three stars is because ARB compressors are great and the product itself deserves five stars.

The ARB wiring is a little bit difficult to understand if your not using air lockers. ARB should think about also including a wiring harness for those that dont need air-lockers to get rid of the excess plugs and extra wire not needed.

This is an excellent compressor. It is very expensive but you get what you pay for. This thing is heavy and very solid. I use it for airing up tires during 4x4 excursion as well as other random things around my house. If you have a 4x4 you need to have a way to air up a tire.

I purchased this compressor to mount under the hood of my Chevy Colorado. I ordered the compressor and was surprised to have it the next day. I had used the free shipping that stated 5-8 days. I was very surprised. I opened the box to find the compressor and parts to be in excellent condition. The box contained everything needed for installation. It even had ring terminals and connectors to wire the harness to the battery. I was very happy with the wiring harness as well. The harness that is supplied with the compressor is designed for lockers, but I am using this compressor for tire fills. The harness was labeled very well and instructions were clear. I had no trouble with the wiring harness. The harness is plug and play. ARB even leaves one plug disconnected so only a small hole has to be drilled to get the switch to the cab area. I simply taped off the wires that I was not using. The wiring had a nice looking switch that is designed to be recessed in a small cut out. I found the switch to be good. The location I mounted the compressor was very tight, but the mount is made to pivot. I was unaware that the compressor body and manifold tube can also be rotated to facilitate various mounting locations. The compressor itself was heavier that I expected, but that was great. The compressor feels well made. I mounted the compressor and made the appropriate wiring connections under the hood. I actually mounted the switch under the hood as well. I used a small plastic gang box used in home wiring and used a Dremel Tool to route out a hole for the switch. I then used a metal plate to cover the box. I was then ready to use the compressor for the first time. I hit the switch and the compressor fired right up. The compressor only ran for about two seconds and shut down. The compressor comes with a pressure switch that shuts down the unit at around 90-100psi. The manifold tube is very small and it gets to that pressure very quick. The manifold tube also has a built in pressure safety relief valve just in case the pressure switch fails. I am not sure what pressure is required to permit the safety valve to operate. I had to source my own fittings to use the compressor as a tire fill unit. I did not purchase the kit offered by ARB because I can build it cheaper myself. I spent an additional $15.00 to make a manifold for my tire fill kit. I had to buy several pieces due to my mounting location under the hood. I also suggest to anyone that purchases the ARB tire fill kit to buy some Teflon tape. I completed the procedure and was ready to fill a tire. It should be noted that I already had 50 feet of 3/8 air hose and fitting to use the compressor. I wanted enough hose to reach from the engine bay to the tires on my travel trailer without uncoupling the trailer. I had been carrying a portable air tank in my truck that holds 120 psi. I decided to test the compressor by filling it up. I turned on the switch and watched the hose fill with air. The compressor then promptly shut off as designed. I filled my air tank from approx 40 psi to 90psi in approx 1 1/2 to 2 minutes. The compressor stopped filling at 90 psi. I was still impressed at the speed given the size of the compressor. I filled a car tire from 10 psi to 32 psi the next day and was equally impressed at the compressor. I think it was a wise investment and would buy it again if I had to go back. My installation took my friend and I two hours to complete. I had a small area to work with and had to build some tools to install some small screws in a tight place. I think my installation time was long, but I had a unique mounting location. Anyone with basic skills could install this compressor easily. I needed to drill three holes. The mounting plate has four holes, but I didnt use one due to mounting location restrictions. This is a good compressor and I hope to use it for many years. Good luck.

Best compressor on the market. I installed airbags on my truck and priced compressor systems. The brand our local tire shop recommended cost twice as much for worse performance. Now I have a much better product with more versatility. Well worth every penny.

This compressor is highly thought of, but I found several issues that I would not expect in a high end product: 1) The housing at the outlet port appears to be made of cast aluminium, and cracked causing a huge air leak. 2) The steel shroud protecting the outlet side of the compressor unnecessarily interferes with the installation of a fitting to the outlet port. 3) The electrical connectors connecting the wire loom to the compressor are difficult to lock. On the positive side, this compressor fits into small spaces, and is pretty easy to install. I am exchanging the compressor for a replacement, and will update this review if necessary after I receive the replacement. UPDATE, FEBRUARY 8, 2018: I have received and installed the replacement compressor. Sexton accepted the faulty compressor back with no hassle whatsoever. Given the good response, I have upgraded my overall rating from 3 to 4 stars, For those thinking about running any sort of air tools from this compressor, you will definitely need an air tank. Dont count on more than a 20% to 40% duty cycle as this compressor cant keep up with any more. This is not a fault, this compressor does everything that it was designed to do. It is fine for inflating tires, air mattresses, etc. I am able to run a pneumatic impact wrench in short bursts to remove lug nuts with the addition of a small (500 ml) air tank. Overall, I would buy this compressor again.

Does what it’s suppose to do, I use it for airing back up my 35’s after a trail, in my opinion it’s pretty fast, a lot faster than the portable one I used before, soon I’ll be using it to provide air for a locker as well

Been using it about 16 months now and it has begun to squeal like a pig, I am talking with ARB USA now. Lets see how this turns out Update #1 They are requesting that I ship it to them (at my expense) Will let you know what that cost? Update #2 Finally got around to sending it back , $18.75 to ship it via USPS Flat Rate Large box. Sent it on the May 17th. , they got it on the May 19th. Update #3 I just heard from them yesterday. even though they couldnt replicate the problem (Screeching when cold) , they are replacing the unit with a new one anyway (+1 for customer service) Update 4. The new one doesnt t like the cold either, but out of warranty now.
