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

Seems like a quality product. I traded for a portable unit. I did not want to deal with all the wiring and finding a suitable place to mount the switch.

This compressor is great, and I would expect nothing less from a company like ARB. I mounted it under the hood of my 2006 Jeep Wrangler TJ, and use it strictly for airing back up after a day on the trails. Will air up all 4 tires from 15psi to 35psi in about 10 minutes. Not bad considering the space and cost of this unit. Will also run air lockers if you choose to go that route. Not much else to say, it is just a compressor. The harness that came with the unit is great, really made for a simple and easy install. Switch fit into the stock TJ blank switch spots with slight modifications (nothing a small file couldnt fix). Worth the money by far. The only gripe I have about it, is that I didnt install it sooner :)

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.

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

It happened to me both with the current locker, and with the one I had in my previous Toyota Prado, that it started to leak air, and they had to open, clean, and reinstall them.

Bought the ARB single stage compressor to air up after a day on the trail. Got tired of waiting for my portable to do the job. Installation was easy and the result was as expected. I like it.

So far so good. I was apprehensive to spend this much on a compressor but it works really well. Ive been using it to air up my 31r16 tires from around 10psi (for sand) back up to 50-60psi and itll do the job in about 20mins which is impressive for such a little pump. That said, it gets HOT. This is to be expected but be ready to have a high temp extension line or it will literally melt your air hose. Well see how she holds up but so far Im impressed.

Super heavy duty compressor. The harness that is included makes install a breeze. No overheating issues as of yet. Fills tires in seconds. The fact you can add a tank and use it for pneumatic tools is awesome.

Arb compressor is known for its durability and quality. I bought the single compressor for my 2019 4runner. Installation process was not so easy but i watched enough youtube videos prior to actual installation. The compressor fills up my 265 70/17 tire from 18psi to 35psi under 2 minutes. The only disappointment is that the compressor came in beat up box that looks like someone dropped it and wrap again. Everyrhing inside was ok and new.

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.
