The CKMA12 is ARB's brushed single-motor on-board compressor for 12V vehicles, built to bolt in permanently under the hood or in the cargo area. ARB rates it at 3.08 CFM free flow and 2.33 CFM at 29 psi, drawing 14.2 A to 25.2 A, with a 100 psi maximum and a 50% duty cycle (30 minutes on, 30 off). In the box: the compressor with its over-pressure valve, bracket and backing plate (also the drilling template), a washable sintered-disc air filter, pressure switch and manifold hardware, a wiring loom with 40 A relay and illuminated ARB dash switch, plus bolts. Inflation accessories and an air tank are optional extras.
Check before you buy: your vehicle runs a 12V system and you have a flat mounting spot. For 24V use the CKMA24; for twice the flow see the CKMTA12 or the brushless CKBLA12.
Not for: 24V vehicles, or long air-tool sessions that need a 100% duty cycle.
ARB began in Melbourne, Australia, in 1975, when founder Tony Brown started building bull bars for four wheel drives heading into the outback. Fifty years on, ARB designs and tests its own 4x4 equipment, from bumpers, winches and recovery gear to Air Locker differentials, fridges and camping kit.
In North America, ARB products are supported by ARB's US office, Air Locker Inc., in Auburn, Washington, which administers the warranty for products bought here.
Authorized ARB dealer. Prestige Truck is an authorized ARB dealer, so what we sell is new and genuine ARB. ARB's warranty period starts on the purchase date shown on your receipt, so keep it with your vehicle records.
ARB rates it at a 50% duty cycle: 30 minutes on, then 30 minutes off to cool.
Yes. The wiring loom comes with a 40 A relay and an illuminated ARB dash switch.
On-board units bolt into the vehicle and are wired in for good, which suits Air Locker activation and quick airing up at every stop. Portable units live in a hard case and clip to the battery, so they move between vehicles and around camp.
A twin-motor unit moves about twice the air of the matching single, so large tires fill faster. Single-motor units draw less current and take less space.
ARB says its twin brushed compressors run many air tools when paired with a 4 L air tank. Check your tool's air demand against the compressor's flow figures before you buy.
ARB lists a 3-year warranty on its air compressors. Keep your receipt and contact us first if anything goes wrong.

Excellent!!! Works great
Yeah great product, I’ll probably end up upgrading to the dual compressor but for now this is great. If y’all were to offer your own installation videos that would perfect the install process, had to spend a decent bit of time pulling apart the harness and referencing the wiring diagram to know what’s what. After understanding the wiring the trimming of unused wires and installation as well as hooking up to my switch panel was very straight forward. Great product great performance does all I need for now, only thing is that wiring is not the clearest on hookup/trimming.
Very high quality compressor and accessories but a royal b**** to install on a bronco
This twin motor 12v compressor is killer!
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.
Great addition to your 4X4.
I ordered the compressor kit for the 6G BRONCO which includes the compressor, reservoir, mounting brackets, wiring harnesses, and pump-up kit. They arrived in a variety of boxes, were very well packed and arrived in mint condition. The compressor and mounting bracket components appear to be of superb quality, finish, and seem very robust.
Great pump
Loom 180414 came sealed with plug assembled so I have to figure out how to pull pins out. Also mini fuse holder is missing
Works perfectly
bought open box and all the parts were with it installed with the Mountain Off-Road Enterprises ARB Air Compressor Mount so I would sit on top of the valve cover for easy access made it easy and painless to install use airline from around town for now and ran down to my fender with a quick coupler so easy air up can take my tires down to 3 psi and will air them back up to 27 psi in around 3 mins compared to my old one that was 7 mins a tire
Excellent product. I had the 12-volt version installed in my 24-volt Humvee and was having a lot of problems until I finally decided to switch to this one, and it turned out to be a fantastic decision.
Easy to install with after market under hood mount.
Perfect for the avid off roader!
Compact design that offers many installation options. Quieter than my old system. Super quick and efficient, and looks great.
Easy install and very efficient! Love this compressor!
I purchased this compressor to install in my 1953 M38 Willys Jeep. I go to the beach a lot, so I need it to air up, and I also need it to run a water pump I use to water remote gardens. It works great. Installation was a challenge, but when I had a problem and was stumped, their support line got me back on track. I highly recommend ARB and their Air Compressors. Now, maybe you could make some cool stuff for all of the old Willys Jeeps out there. Thanks
It keeps blowing fuzes and gets hot to fast and one motor quits working …. When it’s working it’s great but all the other things are kind of a pain ….
This thing is awesome…. Better flow than the mid sized compressor in my garage!
The compressor and tank combination that was recommended for replacing an obsolete air seat compressor was perfect. The sales person that helped on the phone was fantastic in getting us what we needed for our application.
Have been a long time customer of all ARB products, the CKMA12 is a wonderful upgrade from the standard compressor. . . Great instructions and amazing performance.
There is a lot of adjustability in this compressor and it is built with high quality
I don’t have it installed yet so I can’t really review it yet.
We really liked the ARB twin motor air compressor, it looks well built and instructions are quite thorough. I would have preferred to have the switch wire loom offered with on/off switch separate from the air locker solenoid(s) switch part of loom to simplify wiring work. We have a Jeep Wrangler Rubicon with electronic locking differentials and won’t be using air activated lockers , and plan to unbundle the air locker switch/ solenoid part of loom. Altogether great product!
Great product, I bought it for the air locker compatibility and also being able to fill up tires which it does great!
It's nice and fast.
I've had one of these on the last few vehicles of mine. They are worth every penny. Fairly easy to install as well. Mine is on a 2021 Tacoma. Fills my 31s from 12psi to 37psi in about a minute. Not the quietest compressor around but it's not awful either. Typical ARB build quality as well.
Compressor builds air fast, fills 5 gallon tank in less than 2 minutes. Easy install with harness supplied.
The twin air compress is a great addition to my 2023 jeep gladiator. I paired it to the Kraken trie inflation system and the pressure control upgrade kit. I’ve used it a couple of times to deflate and inflate all four of my tires at once. The compressor inflates all four 35” tires from 20 psi to 36 psi in under 10 minutes.
Great compressor but has no instructions for using as on board for anything other than lockers. I have electric lockers and just wanted it for air (tools, tires and such) the wiring is not designed for it, the instructions are not, and nothing in the kit or the hose kit worked. Had to go to a hardware store to find and make fittings
a work in progress. Installing the Bronco specific mount was quite a job. The instructions were crap. Found a good Youtube video to help. I didn't plan on getting a manifold. I just wanted to plug right into the compressor. The first time I had to fill my tires, the air hose (NOT ARB hose) melted and the connection blew apart on the second tire. I didn't realize how hot it got. So now I am planning to install the manifold to keep the hose cooler, but now I don't have the mounting bracket, so this should be an exercise in frustration. I think they could offer better descriptions of the product and more quick connect remote placement options. Still I'm sure it will be awesome once I get the bugs worked out. Also a small half gallon tank hidden under the truck would be great.
super small foot print, and it does a great job with the air locker and airing up a set of 38s after a days ride
I got this compressor as a Christmas present for my husband and then Got a morrflate multi-tire-air-kit. So sorry up down is quick and a breeze especially with two jeeps.
Love the compressor, it works exactly as they said it would and came with great instructions for wiring!
Highly effective, great as it has a smaller size which makes it easier to find mounting location. Ended up mounting at the front passenger foot rest, nice and tucked away. Still pretty loud, however only using it intermittently so it is not a problem.
I have not installed this one yet but have used them in the past. Best compressor on the market everyone should have one.
Was easy to install and does exactly what I need it to. Was able to cut my air up time by a quarter.
Airs up 35s no problem! Would definitely recommend.
Great deal .well made .easy install. Good air up time.
Very heavy duty compressor. Nice to be able to adjust where air ports point. All the wires are labeled for easy Installation. Very happy.
Installed under hood, works great, very convenient. Airs up tires quick. Getting ready for front and rear lockers. Definitely would purchase again.
I have several issues with this product. First, the location where you attach your air fitting is really small. There's no way to get a wrench in there to tighten the fitting down. I tried several fittings. I also bought the associated hose kit, and the fitting is way too large to tighten down with a wrench. Second, this compressor gets really hot. That in and of itself isn't an issue, except that the ARB hose can pop off its fitting when the pump gets too hot. I called ARB and they said not to use that hose attachment. They said they sell something else since the pump gets too hot and someone was burned by it. The guy I talked to at ARB recommended I NOT use their hose kit with this compressor. So, now I just wait long periods of time in between tire fills to allow the pump to cool. I really don't understand how other people are using this pump successfully.
Great product! Quiet and quick. Mounted under seat with mount also available. When istalled the seat will need to be removed. Highly Recommend.
Works just like I need it to. I know nothing about wiring. But, through trial and error, I was able to get it mounted under the hood and connected to a switch system. It's soooo much more convenient compared to driving aired down to a close by gas station.
Nice fit and perfectly tucked away under the Seat...
Works great. A little difficult to install if under hood. Few brackets out there to purchase and even less room to try and access to install but with a little patience and effort can be figured out. Not a beginner project. Nice to have some wiring experience. Product is great. Works great.
If you’re looking for a fast, heavy-duty, high-quality on-board air compressor than this ARB Twin compressor should be on the top of your list. Right out of the box you can tell that it’s a high quality piece that’s going to live up to the demands. The kit comes with everything to power and control the compressor but if you’re looking to install it under the hood, you’re going to need an aftermarket bracket. I used the one made by M.O.R.E, but if you have a 4-door you can install the compressor under the passenger seat with the Teraflex bracket. If you do plan on installing it under the hood and have a 2012 Jeep, then the space is really tight and you have to be careful of the A/C lines. The M.O.R.E kit comes with a split tube to help protect the lines but they still rest on the heating fins, so you need to keep an eye on it. Also, the height for the valve is tight, the M.O.R.E comes…
This has been a great addition to my Jeep. The old knock off single compressor would overheat and leave me stuck waiting on a hot day. The ARB twin easily and quickly inflated all 4 tires (35s) from 15 to 37 PSI in about 8 minutes.
We installed the compressor as part of our Kracken System. We are not mechanically inclined but we were able to easily install it with the video. Thank you.
This compressor was an easy install and works perfect for our needs.
The air compressor inflates all four of my tires up on my gladiator at the same time going to get one for my wrangler
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.
Would’ve got all star rating, if you didn’t have to buy Additional stuff to make it Complete its task it would be nice if it came with the air chuck. even if it was a cheaper one so that you could pull it from the box hook it up and go.
it arrived and spent the day installing and come to find out it has a bad pressure switch. waiting on new one from ARB
Took longer than expected but I was able to install it in one shot and it works great!
Seems to be a great product so far and runs my locker well
Open box purchase came with almost everything. 1 pig tail was missing but the price was too good to pass up!
Tired of driving to gas station on low tires, decided to look around for an on-board compressor. All routes let me to ARB, though for the use I need I purchased the Single On-Board and am wuiet happy with it! Mounted it under my seat as I have a 2-door and cargo space is limited!
This Compressor works great and the kit came with everything you need.
Awesome air compressor. Fills 35's from 18psi to 36psi in 1min
Good air compressor. Gets very hot after airing up 4 35s from 12psi to 28psi. Wait a bit before touching.
Best compressor hands down! Mounted underneath the hood and ran quick disconnect to the grill for ease of use.
Small footprint but big results. I have mine mounted under my seat to keep it clean and away from heat.
The ARB Twin On Board Air Compressor is a game changer. I have it mounted under the hood of my 2015 Wrangler JK Unlimited. Mine is a few years old and I have no complaints. Installation wasn’t bad. I highly recommend the ARB Twin On Board Air Compressor
It's a great piece of equipment. I love this thing. Installed it on a 2018 JK Jeep Wrangler Unlimited with a MORE mounting plate. I also added the remote fitting to get the added convenience with the access point. I'm really happy with the purchase and the peace of mind it brings into my off roading :)
tis a good little compressor. Just dont leave it one when leaving hunting camp. It will kick on and off and make you think you messed something up flying over them washboard roads
Awesome on board air system air up 40 inch tires no time flat.
Got this to replace the compressor that only accuated my lockers. It is big but it is powerfull
I bought this unit to use with my up/down air system , works great , will recommend .
I tried a small portable air pump like most of you. After spending an hour to air up when I was in Georgia I knew I had to get something better. While there are faster pumps this still gets the job done in about 10 minutes. Also if you have a two door space is limited. Last week when I was in North Carolina and Tennessee I aired down several times and didn’t dread knowing I had to air back up.
Easy and fast install under hood, 2016 JKU. Tested this weekend, 2 minutes per tire, 37" to 30 PSI
This compressor is very fast and efficient. Love it.
I couldn't believe how fast this compressor filled up my Jeep tires! (35's) Expensive, but worth it!!
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 twin) great unit, and I’m definitely not disappointed I bought it.
This compressor works amazing to air up after being on the trail. I air down to 15psi and this brings a size 35 up in 2 minutes. Buy the air up kit the two work together .
Mounted under the brake master cylinder, plumbed to a 3 gallon tank, I aired 8 33’s from 18 to 32 psi in 20 minutes. Our other buddy used his Milwaukee, airing 4 tires in the same timeframe.
Installed prior to Jamboree in Oct. Worked great to air up after the day on the trails. Wish I had purchased and installed sooner. Mounted under master cylinder on firewall of 2018 JL. Will air up all 4 tires in 5-10 minutes depending on how far deflated. Great piece of mind knowing you don't have to find a gas station or drag around another piece of equipment. Always with you and ready to go.
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
It’s Amazing works great the dual is the way to go. So much faster. Thx again Dan in phx az
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.
The product is great, but the instructions can be confusing when it come to wiring in the switch. Just know if you are using it to Air up tires then use the Isolator switch set up for the switch.
Only used a couple of times so far and works great for the air locker and airing up the tires but does get hot when airing up all four.
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
It's well built and of good quality, not at all like the bargain store compressors.
The arb on board air compressor is great Although they don't make specialty brackets for my specific tacoma I was able to fabricate one and install the compressor in the desired location it works great and I cant say Enough about it great product all as round would Definitely recommend it
For my needs this compressor is great. I have 35s on my jeep, and airing up and down doesn't take long at all. I did have to order a bracket to fit it under the hood.
