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

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.

Best compressor on the market. I installed airbags on my truck and priced compressor systems. The brand our local tire shop recommended cost twice as much for worse performance. Now I have a much better product with more versatility. Well worth every penny.

This thing is a lot more powerful than I was expecting (used to lesser portable compressors). I mounted it under the hood of my 4Runner with a Slee off road bracket. Paired it with an air on board oem looking switch and it fit and wired up just fine. Inflated all 4 stock sized tires 265/70/17 pretty fast. Pretty expensive but it seems like a quality piece.

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...

Nice products, heavy duty I just install it this week in and its works fantastic...easy installation... down side they deliver the package to me its broken and open looks like they drop the box...they should double the packaging specially the compressor is heavy..ither than that looks perfect to my tundra...

Ordered this from a warehouse deal as new in original box. Even had the inspection sticker on it from Amazon that it was all there. Parts were missing (air filters, switch, brackets, the instructions, and wire harness was cut and spliced, scratches all over the compressor). Needless to say it wasnt in like new condition and had been Installed and then thrown back in the box. I know its not ARBs fault but come on Amazon, do a thorough inspection before you put it back on the shelf. The person that bought it before me basically stole a bunch of parts and through it back in there. The only reason for three stars is because ARB compressors are great and the product itself deserves five stars.

Overall a good product but the mounting system needs to be better thought out. I purchased this to replace a QuickAir 1 compressor mounted in the engine bay. The two are roughly the same size with the ARB being slightly taller. I have yet to hook this up to my existing 2.5 gallon on-board air tank and try airing my 35 tires back up so I cant speak for ARBs claims that this compressor is significantly better than their original smaller compressor in that respect. The silver tube at the top of the compressor is an air reservoir which is there solely to have a small reserve for actuating ARBs air locker(s). There are three ports. The tube is designed to have both locker solenoids installed on one side and the pressure shutoff switch installed on the opposite side (opposing one of the solenoids). The silver tube can be rotated to some extent to point the ports at a different angle and the silver tube can be rotated to position the solenoids on the opposite side of what is shown in the illustration. Theres quite a bit of flexibility for positioning the solenoids. Since I was replacing an existing compressor and didnt want to re-engineer the entire setup, I installed both solenoids on the silver tube vertically (air vent pointing up). Note: I run vent tubes from the solenoids to exhaust outside the engine bay under the chassis in a protected location. Passengers have complained about occasional exhausted fumes from the differential(s) drifting back into the cab if the window(s) are down. The issue is that there isnt enough clearance between the two solenoids when positioned parallel to the silver tube for the fittings on the solenoid vents to fit so I positioned the solenoids vertically. This significantly increases the height (or width if the compressor is rotated 90 degrees in the mount). If the compressor is mounted on a bracket on top of a fender well as mine is this may cause hood clearance issues. Fortunately, I had just enough space to clear the solenoids. The compressor itself can be rotated either way 90 degrees from the mount base plate and at any degree in between. Also a nice touch. That gives a lot of flexibility in mounting locations. The single negative point Ive run across to date is the mount bracket (base plate) and as far as Im concerned theres no reason for it. This is a simple problem and should have been considered by the engineer(s). Not a big surprise to me as this isnt the first ARB product where the engineering has fallen down on a simple, basic point while acing all the complicated issues. In order to mount this compressor, you must have clearance to the bolts that mount the black steel plate from the sides or bottom OR clearance from both ends to the bolts that mount the compressor heat sink to the black steel mount plate. The blue band is an aluminum heat sink that wraps around the compressor motor and attaches the motor to the base plate. The band/motor is attached to the black base plate by four Allen head screws - two from each end running parallel to the motor. Unfortunately the body is larger in diameter than the black steel base plate so its not possible to get a socket onto the bolts from the top. That means you must use the supplied carriage bolts and a boxed/open end wrench on the nuts from the side or a socket from the bottom. Presumably, the idea is to remove the motor/heat sink from the black steel base plate, attach the base plate to the body/fender/stand/etc., then re-attach the motor/heat sink to the mount plate via the four screws. Thats great as long as you have at least 6-8 of clearance AT BOTH ENDS or to EACH SIDE. The four screws run through rubber bushings which makes re-installing them very close to impossible using just finger tips. At the end of the day it took 6 hours to install the four screws and two of the carriage bolts (one one one side at one end, and one on the opposite side at the other end). It proved impossible to install the other two carriage bolts without drilling 3/4 holes through the fender and fender skirt. Obviously no thought was put into actually mounting this in real life where there wasnt a foot of clearance all the way around the compressor. The solution is simple. #1 Make the blue heat sink band a two piece clam shell unit. Half the job is already done. The band has two screws that loosen to allow the compressor to be rotated 90 degrees. Put two on the other side creating a clam shell setup. Take the four screws out, lift out the compressor, bolt everything up and put the compressor and four screws back in. #2 Make the black steel mount plate a two piece unit. From ARBs illustrations, it appears at first glance to be that way already. Its not. Make it a two piece unit so that each end of the bracket can be flipped 180 degrees so that the tabs point towards the ends of the compressor vs. the center. This would allow for using a small 1/4 socket wrench with a long extension to bolt the compressor to the body/fender/whatever and not require removing the compressor/heat sink assembly from the mount plate. The compressor comes with wiring and a bag full of hardware. Since I already had a compressor (rated at a higher amp draw) with dual air locker solenoids installed almost all of it turned into misc spare parts. One piece that I REALLY wish they would have put in the bag is the T that they supply in one of their other kits. The T screws into the port used for the on/off pressure switch and allows for the pressure switch to be installed and still have an open port to attach an air line for an air tank. Or, again a simple solution, would have been to have four ports on the silver tube. Overall the product seems to be decently built and I expect it to do what its supposed to do for some time. Were I doing this on a new vehicle without a previously installed air system, I probably wouldnt have gone with a compressor at all and used a QuickAir CO2 system to actuate the air lockers - or maybe I would have gone with mechanical lockers instead of ARB air lockers.

Heavy duty. Tested putting the bead on a 33”x10.5”r17 and it did great. Fills tires fast. Major complaint is the instructions suck. I got the air up kit too and ended up running pipe out of a splitter on top in my GX470.

The ARB wiring is a little bit difficult to understand if your not using air lockers. ARB should think about also including a wiring harness for those that dont need air-lockers to get rid of the excess plugs and extra wire not needed.

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 :)
