5.0 This is the compressor you want!

Thr ARB CKMTA12 compressor is awesome! Makes airing back up so quick and easy. The included instructions are great and make installation is very straight forward. I paired this compressor with the 4 wheel tire inflation system from Up Down Air and the set up works flawlessly!

5.0 Great OBA compressor

Comes with nicely setup wiring harnesses and activation switch. The power supply harness is about 6' long and the actuator harness is about 10' long. I mounted this in the bed of a pickup under a metal cover. I feel it would be a little loud to use in the passenger compartment. Might be okay if you can put it behind/under stuff that will muffle the sound. Airs up 37" tires from 15psi to 32psi in less than 2 minutes per tire. Can't wait to get an air tank so I can use this compressor for more things. Seems like it will work great. Only complaint would be that it doesn't come with any type of air fitting, just an 1/4"NPT port. Not a big deal and I knew this was the case before I bought it. I mention it more as heads up for future buyers that you will need to plan on at least buying an air coupler with 1/4"NPT male end. I opted for the ARB Inflation Accessory Kit. No regrets with this product.

5.0 the alpha and the omega of compressors

this compressor is for those who want the very best of what is offered. for the size, it is a beast. it will fill up my 35s in under a minute and a half without a tank, with a tank it takes a minute from 5 to 35 psi. mind blown with how awesome it works. it is a little large for under the hood of a jeep, but fits perfectly under the seat of an XJ. It is quiet, high output, beast looking, and you can snorkel it for all your underwater applications.

5.0 ARB Twin Compressor is fast!!!

At first I hesitated buying the ARB Twin Compressor as I had one of their first compressors, around 1997, which was slow and broke down shortly afer the warranty ran out. But after looking at the Twin Compressor I liked the quality of construction, the mid range amperage draw,the quality of the electrical connections, and that it comes with the complete wiring harness that runs from the compressor to the dash swiches. Install was very easy, the only part that took some thinking was where I was going to make a hole in the firewall to pass the harness through. I mounted the compressor in the engine bay (95 Wrangler) on the passenger side. It's plumbed to a 2.5 gallaon air tank and the compressor comes with a pressure switch that closes at 135 psi and opens at 150 psi. I have 31X1050 mud terrains on my Jeep and from 0 psi to 32 psi, the compressor was able to fill the tire to 32 psi in exactly 1 minute and 5 seconds. The outside temperature was 68F degrees and the elevation is 300 ft. I'm very impressed and pleased with this twin compressor setup. The included wiring harness made installation a breeze. ARB has winner in their twin compressor offering. I'm very satisfied with my purchase.

How loud is the compressor? Too loud to be mounted behind the back seat of a mega cab?

Asked by dm357 from Colorado on

Thanks for the inquiry dm357, the ARB 4x4 Accessories Twin Air Compressor part # ARBCKMTA12 is much better on mounting under the hood or along the frame, it is a little noisy for inside a cab.
