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

Where you been all my off roading life !!! With the 4 tire inflation system I make. And the twin compressor w/ 1 gallon ARB air tank. It take 7 to 8 minutes to air up all 4 - 35 tires from 10psi to 38psi. Worth every penny

This thing is powerful! I was surprised when it arrived and I opened the box. This thing was heavy In a good way tho. Well built with quality parts. It comes with everything need to wire it up and to switch it on. You only need to plumb the air side of it. I mounted on the inside up high on the rear passenger wheel well. On my 2006 gmc sierria. I have it going to a 7 gallon air tank and a 25ft air reel where my Spain tire used to be.

This little gem is the best compressor out there for size and weight. The dual compressor is nice too but its over double the weight and with a 100% duty cycle I can sit in the Jeep and wait a little longer while I air up (I have tpms). Its a pricey little bugger, but Ive bought two of them now for both Jeeps. Buy once cry once!

Good pump. Turned it into a mobile unit. But... I have not used it in a cave.

I’ve ordered $10 items off of Amazon their box better than this $500 air compressor. Hopefully ARB made these strong because this box looks abused.

MADE IN CHINA. Thats the FIRST thing that should be known about this compressor, so keep this in mind. With that said, so far, it appears to be a top quality compressor. If you are used to the big box compressors here are a few differences between the ARB and the standard Chinamercan stuff: - quiet, it sounds solid and tight, it doesnt make a racket, a nice mellow tone - hard-wired to the battery, no more jumper cables, fumbling for the box, putting the compressor back in the box, etc.. mount it anywhere, including under the hood - switch, relay, and wiring harness all included, mount the switch on the dash somehwere.. use a dremel or whatever you got to cut a space for the switch - good air compression, unlike other big box compressors this one never sounds like its struggling, instead it sounds like it is well capable of doing what its supposed to do, this is phychologically reassuring - manifold with pressure switch, this means you hit the on button, it fills the manifold for a split second and the compressor STOPS, now you can go from tire to tire and fill up without having the thing run constantly - the kit does NOT include a hose or tire inflator - sold seperatley... Overall, so far so good, though I havent used it much (thankfully) .. mah use is primarily for tire fills and some random blow-gun action (ie cleaning stuff) What would be better? If it was NOT made in CHINA. Japan or Australia would be prefereable, even if the price were DOUBLE.... Alas this is the way of thy world... I suspect China will have more tiers to their quality as demand and competition continue to grow...

This is probably the best on board air compressor you can find on market. It is really powerful even for ait tools. Yes you need to have certain skills to install it. Can be use for air horn, locking differential, adjusting wheels pressure for different off road condition.

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.

I purchased this air compressor because of the company reputation and many good reviews. Let me start by saying that the quality of this compressor is very good. I dont expect any performance issues with it and I love the small compact package this offers. Now I want to dive into some of the deficiencies that many people didnt mention and that you should know before you make this purchase. Watch some installation videos on this, then understand that those videos dont tell you that this is an all day or maybe even all weekend install like it was for me. It all seemed pretty straight forward however some details brought my install to a halt even though I consider myself a very capable mechanic. So block off a good chunk of time to do this installation. Buy your own air fittings from the hardware store. I purchased ARBs actual quick connect accessory kit thinking it would streamline the installation. It was a joke. I spend 46 bucks on a kit that I couldnt use. Why? Because 2 of the 3 air ports on the compressor are different and none of the fittings in the accessory kit allowed me to actually connect the quick connect fitting. Just go to the hardware store and buy yourself a regular air hose quick connect fitting and a 1/4 inch T fitting. Unless you have lockers dont plan on being able to use the two blocked off ports on the air chamber on the pump. Ill be returning the accessory kit. While the included wire harness is in fact pretty plug and play its very over complicated. ARB gives you a harness that controls the pump and the option for two locker switches. Most people arent using lockers. In order to make everything work you have to use the whole wire harness even if you arent running lockers. I ended up cutting off all of the unnecessary wires for the two extra switches because I didnt want to have to try and conceal a bunch of wires not being used. Im a electronics technician by trade and they could have made this harness much more streamlined. Thank goodness for the mounting adjustments. I was able to tuck this pump in a very small area and the ability to rotate the pump and air chamber really helped get it right where I needed it. Once everything was hooked up and powered the air compressor works well. I have not yet used it to completely fill 4 tires but I dont have any doubt it will do the job.

Very good compact air compressor. The wiring harness was a bit short for the location I chose to install it (Rear Cargo Area) and extending it was slightly challenging due to the wire gage required to supply the correct voltage. If you intend on installing it in an engine bay or in the front of the cabin, the harness length should be fine. Also, it appears during assembly, the housing was bolted together slightly askew which marred the blue portion of the compressor. This is simply cosmetic, but the item was not listed as a scratch&dent.
