Mounting ARB Air Compressor

[UNC Rubicon]

Anyone find the compressor gets to warm under the seat?

I dunno about “too warm” but it does get hot...especially the braided hose and connectors. With that said, I aired up 4 35s, 4 33s, and 3 32s back to back last weekend. The compressor didn’t skip a beat.

The under seat location, while convenient, doesn't promote the best air flow and heat dissipation. Unless it goes into thermal and shuts down, you shouldn't have to worry.

I had the ARB single mounted under the hood (over the exhaust manifold) on my JK and after a day on the trail I was lucky if I was able to air up 2 tires before it overheated and went into thermal.

Isn’t the under the seat mount location way cooler than in the engine compartment? When it’s in extreme temps at all times - never mind just airing up.

Depending on where you mount it you're likely to get much more airflow in the engine bay than under the seat. How many people actually run them with the engine running and the hood closed? If you're talking to run lockers it's a very small amount of air needed and a very short run cycle.

I don't know if I agree with more air flow mounted under the hood. Any under hood mounted compressor is going to suffer from heat absorption from the engine if you've been running trails all day and air up immediately afterwards.

Why does no one consider the Kleinn system? It mounts underneath the vehicle and is waterproof. Seems like that would be the best option but no one ever mentions it?

No way would I put one under the seat. My little craftsman unit I use at home will burn you after 30s of use.

That's because Kleinn only puts out 2.0 CFM at 0 psi. ARB puts out 6.16 CFM at 0 psi.

I have an ARB Dual Compressor, I am curious how people are mounting it in a JL?

<EDITED WITH UPDATED THREAD INFO>

Portable.

I have a 2dr and how does the underseat mount work when flipping the seat forward? Might be a good option when airing up to have the seat flipped forward. I am considering the 4 tire deflate and inflate kit but will there be an issue with the seat frame airline mount when flipping the seat forward?

No issues. Does not interfere with seat motion at all. No need to move the seat. The 4-tire inflation kit also works fine.

Thanks appreciate the reply.

It’s kind of hard to get good pictures...they don’t show like looking at the real thing. Here’s a couple more. Shows the top part of the bracket.
Was able to do the installation without taking anything apart.

Any pics of the wiring across to the aux switches?

This is what I have....

This is how I mounted mine. All you need is an L shaped bracket. Pics are with a temporary bracket I made, then I had a machine shop make a permanent one.

I had my ARB twin under hood. Had an air leak while at E.J.S. Moab and was happy to find ARB had a couple techs in town. They sourced the leak, hose fitting elbow on ARB. Problem was, nobody could get a wrench on it without unit removal. Neither they or I was going there, in the parking lot @ E.J.S. But, If that wasn't bad enough. Both techs said, "that was a bad location because it preheated(heat soaked)the compressor". They both said the ARB is a tuff little unit but that was a bad environment. I mentioned 3 inside locations I new about to them and a sales rep. They all said the M.O.R.E. location was the most preferred because of air flow. That is were my ARB is now, damn things are too expensive to install in a less than ideal location.
