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

I loved this compressor when I first got it, but it just doesnt hold up. Ive had it about 6 years and good thing its a dual because one side or the other is always broken. Ive had 3 brush failures, and one broken rod bolt. The compressor itself is fast, and relatively simple to fix. I mounted it under the passenger seat and its a pain to get it out to fix it. I currently need to swap the motor from the broken rod bolt in to fix another motor brush problem. When the motor gets hot, the wire comes unsoldered from the brush. Im about ready to trash it and try something else.

Compressor is great but it did not come with everything in the picture no external tank or line or brackets

Very well built, easy installation. Great Compressor

Excellent 12v air compressor. Im so impressed with it that I would never buy a different one, except maybe the twin version. This one has been so useful! I use it to air up tires at the end of a trail, blow dust off of gear, and inflate my air mattress. Ive had mine installed and working for over a year now. Install was a breeze thanks to the unique mounting system. I have mine mounted inside a small hard case that I mounted in the back of my 2005 Frontier. My only complaint was the instructions, which assume youre using it to power ARBs air lockers. The supplied wiring and hardware is great, but I had already installed a relay block and auxiliary fuse box, so I had to figure out how to make the compressor work with my pre-installed wiring. Overall though, the install was very smooth and pretty easy. The design of the compressor is fantastic and feels very solid. I would not ever worry about how long it would last. Performance out of it has been nothing short of outstanding. Its filled up my tires as well as many friends tires at the ends of countless off road adventures and has yet to have an issue. It does get warm but never overheats, even after very prolonged use. I can fill my 285/75R16s from 20 PSI to 42 PSI in about 2 minutes per tire, which is great. It has limited use with a blower nozzle, but thats just because I dont have a tank rigged up to it. For my purposes though, its good enough without the tank. Overall, I cant recommend highly enough. Its become one of my main essentials now.

well I received item really fast(thank you for that) unfortunately I tested it, doesnt work, the box in came in was in shreds they put in another box that was intacted, It looked like it was a previous return, not really sure, they said its not returnable, so I have a big paper weight, use caution!!!

To be honest, I was surprised with all the great reviews now that I have it. On some vehicles it’s easy to mount, but took innovation on my Dodge Ram 2500. With how popular this company is, it seems logical to argue they would have a solution for almost all Overlanding trucks. Additionally, the wiring directions were horrible, and I had to watch a million YouTube videos. I’m not great at wiring but I’m def not bad at all. The problem lies with wiring the toggle switch, because the wires that come with it are really short (about 2’) and it is difficult to wire. Most people wire the toggle switch into the fuse box (because of how difficult it is to wire it as the instructions call for) which required me to have to go to auto part store for special adaptors to do this operation as well as more wires to extend their length. In my opinion, they could have done a far far better job at creating more user friendly instructions for the DIYer person and included wiring components/solutions for all sorts of vehicles because that stuff is cheap. Be prepared because it won’t be a quick wire up and out project unless you do a lot of this type of work. Oh and to top it all of, it didn’t even come with an adaptor to hook up an female air coupling with the pressure switch. If you don’t know what I am talking about then look into it because you’ll need a special component that they sell in their additional tire inflator kit. This whole thing stinks because the compressor seems amazing and works well, but the experience of having to get a bunch of extra stuff to put it in the car was mediocre. Get it together ARB and serve your customers right.

This air compressor works really well. It puts out a lot of air really quickly. I use it on my 4x4 rig to run my ARB air lockers and to air up my tires. It draws a lot of power, so don’t use it for extended periods of time with the truck off. But other than that it’s perfect.

Installed under the passenger seat in my Jeep JL. Works great for quickly airing up tires but won’t run air tools without a tank

Had a hiccup with it where it leaked in the second wheeling trip I took it on. But it somehow self healed miraculously and works great again, runs the lockers and airs up my 42s just fine. About to out another one in my tow rig to run its new air lockers and such as well. I did contact ARB and they got back to me asap and were willing to replace it as well. Seems a seal got hit after airing up 2 large tires back to back and leaked a bit.

It seems that this was only meant for lockers. Using this to inflate tires appears to be a poorly thought out after thought. There is an over priced tire inflation kit. But you can buy a 1/4 NPT tee and put it the pressure sensor port and then have the air sensor and hose fitting on the tee. Most likely, everyone that buys this is going to need to modify the wiring harness to make it work. Since there are no kits you have to figure out what you need and where to get it. I tested it by dropping one of my 35” tires 10 psi then filling it. It took about a minute to get it back to 36 psi.
