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

This ARB air compressor is a fantastic piece of equipment. I installed it in the engine compartment of my Jeep Wrangler. I can now air my tires up after having some off road fun. Works like a charm.

takes about 5 minutes total to reinflate my 31 inch tires

Showed up with a broken connector. Good thing its inside my rig. The pressure valves arent set correctly they release before it shuts off easy fix with new springs. Happy with it other than those 2 issues. Airs up a 37/13.50/17 from 3psi to 30 psi in 3.5 minutes. Read the instructions! You may not need to remove the cover at like it states will save you 20 minutes of asking why. Highly advised to get the 1 gal air tank!

What can I say? It works and provides enough air for my ARB rear locker. I wouldnt expect it to do much more beyond lockers, so it really is a one-trick pony. Other than that, time will tell how reliable it is, but given that it is ARB made, I dont expect issues.

Yet another high quality product from ARB. The performance has exceeded my expectations by a lot. After a year, my follow up: I was a little disappointed to find out this compressor is made in China. But the performance is rather incredible. I actually did an experiment to put some numbers to it. Keep in mind, the low tire pressures I run help the performance. I run a 38 x 13 Super Swampers TSLs at 4 PSI when Im off-road. On rare occasions I need to run on the road, so I like to air up. This compressor will take these big tires from 4 PSI to 11.5 PSI in exactly 30 seconds. Im airing up 4 tires in 2 minutes.

I have a 1998 Cherokee that has had an air locker of some sort since about 2000. For many years I had a Quick Air II compressor which served me well but not perfectly. I had several issues with it over the years. It finally quit completely about 6 years ago. After that I installed an on-board air compressor driven by the engine. This too turned out to have issues and I abandoned it. After that I returned to an electric compressor and bought a small Harbor Freight compressor just to run the lockers (all of my other setups were used for airing up and the lockers.) The Harbor Freight compressor turned out to be nothing but problems. Obviously you get what you pay for. The first one broke the pin on the crankshaft. I modified the compressor to use a bolt in the crankshaft and that fixed the problem. Then I had problems with it over heating. Finally one of the reed valves on the piston broke. I mention all of this to highlight all of the problems Ive had over the years with something that is dead simple. I finally decided to quit messing around with junk and go with a compressor made by a company who specializes in air lockers and also has years of experience and a great reputation. Looking at the price of this tiny little guy I though it was very pricey for what I was getting. At the end of the day though, Ive spent much more on unreliable and frustrating solutions. One major benefit, in addition to quality and reliability, is the fact that it is already set up to accommodate two solenoids and a pressure switch. I also believe you can get an air up kit for it if youd like. I decided not to run an air gauge as I didnt feel I need one but I believe it will also accommodate one if you would like. In addition it includes wiring harnesses to connect everything. I cannot comment on whether they worked or not because everything was already wired by me from my past setups so there was no need to read invent the wheel. One thing Id like to say is I dont think I would recommend the air up kit for this compressor. Not to use for airing up tires any way. If you were to use it for airing up balls and small items, maybe, otherwise get a larger portable compressor for airing up. Harbor Freight does make a larger portable compressor that looks suspiciously like a Viair and works quite well. All of this said, this is a great little compressor for running your air lockers. It airs up quickly and has plenty of capacity for this job. It is very compact which makes finding a place to mount it that much easier. After years of messing around with my air source on every wheeling trip it was nice to have a system that just plain worked and needed zero intervention! The price for this little guy may seem a bit high but in reality it is worth every penny.

Its the best and fastest compressor out there. It does get hot but only if Im airing up several vehicles. I installed mine under the passenger seat to keep it cooler and cleaner.

Great little pump. The wiring harness ended up being a 6 hour battle before I finally tore it back out from my install. End up having a broken ground wire in the harness. Rewired the entire system using only the necessary parts and it worked as it should.

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.

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.
