12V Twin Air Compressor Replacement for CKMTA12 Universal High Output On-Board Air Compressor

So far so good. I didn’t want to spend the money on the ARB brand so got this. Installed under my Jeep seat. I’m really impressed with it. Fills the tires quickly and not that noisy. I’d recommend / buy again.

I’ve had this for 2 years and 40k miles on my Tacoma. Running 2 lockers and airing up tires. Been perfectly operational. I’ve installed a few of these and ARB branded ones. You can not tell the difference visually or by weight . They even come with the same manual and wiring harness.

So far so good ..

Nearing my purchase, I watched several videos about this type of compressor and chose this model. It’s affordable compared to the more well-known brands and performs the task I needed it for. I also upgraded the pressure switch to a higher PSI one, which helps me fill tires quicker during my work trips. It’s been pretty handy so far.

This air compressor is great! Seems identical to the ARB to me and have not had a single issue. It airs up my 35” tires with ease and doesn’t get too hot. It is loud but not any louder than an ARB. It has a very high air pressure output.

Well, it was fun to install. The connectors are really sloppy and hard to get to connect. The connector for the locker does not mate up with an ARB connector, they look the same, but if you look close the wire connectors are at different places in the plug. It took me a while to get this put in, I made a custom bracket to go around one of my batteries (1995 Dodge Cummins) to keep this close to the front air locker and the power source. Then I had to install a PODs type switch box, all of this to say that by the time I was finished with the install it was too late to return the pump. I had everything up and running, but it was running too much, I had an air leak. I used a few wraps of Gorilla plumbing tape (I usually use paste, but did not want to chance getting some in my air locker system) I had a short nipple, to a T to an air chuck and to the locker valve. There was a leak between the nipple and the T. I am trained as an auto tech, and have spent 20 years after that being a handyman/contractor. When I took the fittings around one more time to tighten things down, I heard/felt something let go. I trashed the threads on the pump. My guess is they are low grade alloy. I have years of experience tightening things and these were not under an undue amount of pressure. I guess I will put this $300 paper weight out of sight (out of mind) and order a real ARB. I did read that other people have been really happy with these, and that is just it, with low quality parts and minimal quality control some are great some have poor castings, or other parts, like mine. I really think some of these knock offs are made out of the rejected parts from the quality brands, but I have no proof. If there was a way to contact the manufacture I would see about getting replacement parts, but Amazon said to search for their information in a browser of my choice! WTF, Amazon you have these sellers contact information! The good news is, most of my work is done when the ARB comes, and I know I can get service and parts for it, if I ever need them. You do get what you pay for, both in hard goods and service.

Works just like the real deal. Would recommend.

Just received this compressor and I’m concerned about the quality. The screws holding the fan inlet filter don’t fit right, are loose and one is missing, another was in the bottom of the box. I’m going to test this right away and decide if I need to return it.

Good quality, looks just like an ARB

So far great product.

Works great. No issues and looks like the original.
