Bought and installed this about a year ago. ( I still need to mount the air hose externally so I don’t have to open the hood each time I need to access) installation of the unit was pretty straightforward and easy to follow, The old Jack mount in my engine compartment was a great spot for me to just install on a flat surface. The unit itself can be altered and adjusted to fit pretty much anywhere. For me, this unit is working out great, I only need it on occasions where I don’t have access tour outside compressor. Fills my 33 inch tires up in about 1 to 3 minutes each depending on how low I dropped my air pressure. The unit does get very HOT when I have to use it for long periods of time. (if I needed this unit every time I went wheeling I would definitely get the ... MoreBought and installed this about a year ago.

Just installed this in a Jeep TJ. I took the time to locate it under the brake booster as this is like an unused area and would be a good place for it. Was going to run wires and run it thru the Rough Country MLC-6 switch pod, but the ARB harness is kind of small and is already set up for the pressure switch and solenoids I decided to use it instead of running my own wires. After I installed the compressor I then ran the wire harness to the switches in the switch pod and battery. Compressor works good, kind of hard to find air leaks for the noise, but I used a soap/water to find 'em and of course all the leaks were on the manifold for the solenoids. Tightened those up and works fine. Cycles off/on every few minutes, will probably add a little larger tank and mount ... MoreJust installed this in a Jeep TJ.

I installed this little compressor in my 2000 TJ for airing up 35 inch tires after off road driving. This is the fastest compressor I have ever used, airing up 4 35s in a few minutes. I highly recommend this compressor for it's reliability and compact nature.

Mounted the pump in the storage compartment in the back wired with 8awg wire from the battery. I did that so the length of the wire run would not be an issue. Then ran airline to the under side of the driver seat where I customized a switch panel and hose connection for easy access.I also plumbed in the pressure switch under the seat because most of the wire harness is located there. This setup is ready for when I go to air lockers too
I have used my ARB compressor several times after I installing this on my 2015 JK, . It works a lot better than the portable unit I used before.I am running 31" BFG KO2's and deflate my tires to 20 psi when I am off road. It only takes about two minutes to re-inflate each tire to 38 psi before I get back on pavement.Sure makes the off road ride a lot more enjoyable!Caution! The compressor end of the air hose gets very hot! Hot enough to burn.
Easy to install does require a separate bracket for bronco. For some reason my kit did not include the hose connection or pressure regulator fitting. Fills my 35s easily
This is a well built compressor. It was a simple install in my 2022 Bronco. I was able to make my own custom mounting bracket and support for about $30 including paint. It is easy to rotate and adjust in the mounting bracket with a simple allen wrench. I connected it to aux switch 6 so it's easy to turn on and off when needed. I tested it right away and it added 10 lbs. of pressure to my tire without any hesitation. I can't wait to use it off road!
After 2 1/2 years of using $20 tire inflators from Walmart, I finally sprung for an ARB single air compressor. Build quality is very good and it will inflate a 35 in no time compared to the cheap units I had been using. The compressor also comes with a wiring harness to simplify the installation. The only negative things I can say are are relatively minor. The first is that you will have to add an air chuck for you hose to connect to separately. The second is that depending on your mounting location you might have to extend the wiring harness. Overall, I have been very happy with my unit and would recommend for anyone running up to 35's. It could handle 37's but an ARB double unit would be more efficient for 37's and bigger.
I just installed on a 2022 Jeep Wrangler Rubicon Eco-Diesel behind the front tire on driver side. So if you are using a bracket from Wayalife, it will not fit because the windshield washer storage is on the driver so you cannot use one of the bolts attachment. So the way I did it is drill another hole and did some little bending to make it work. I am still in the process of testing my air compressor but so far it runs perfectly and no leaks. I wish the wire is a little longer where you attach the wiring connector for power.
This air compressor is an amazing little workhorse and a must if going off-roading and airing down. It fills up my 33 inch tired faster then any gas station air pump i’ve used. It’s a little pricey when compared to other portable air compressors but like the old saying goes, “buy once cry once”. I’m super happy with my arb compressor and will be purchasing all of my future Tacoma mods and gear from Extreme Terrain.
