So last night I ordered new gears and front locker from ECGS!! I went with 5.29's for my 35's and added the front ARB because why not when doing all the work. Now I need an air source.

I'm looking at the ARB dual compressor as it would be awesome to have something that can air up my tires as well as run the front locker. Put a small tank on it and I can even run some air tools if needed. Cost for the compressor and manifold is about $720.

Other option is a Powertank type option. They have the manifold to run the ARB, but that is an added cost. Total cost is about $760 for a 15lb tank setup. I have a shot about 10 minutes from my house that will fill the tank for about $25.

I would probably mount either one in the rear hatch, the ARB in the storage compartment and the Powertank in the storage area. Line runs would be about the same, and would probably use stainless lines to get more durability and less chance of breaking in the Colorado winters.

So what do you guys think? I want something that's on board since I'm going to have the air locker. I'm open to many options, just want to get something reliable that I can setup and mostly forget about.

Look at the Smittybilt 2781. Over 5 CFM and paired with a tank should do it all for you. Nate put two in his LR for his overland build: Land Rover - YouTube

As for air tools... get a good quality 18V impact - better performance and lower weight.

I just went with a single arb compressor, should still be able to fill tires no problem especially with one of those 4 way hose setups. Just takes a little longer than the dual arb. Yota1 has a pretty sweet bracket for the single compressor. The power tank is a nice option but you’ll get tired of filling the tank especially at 15-25$ per fill. Pretty sure the arbs are back ordered, I’ve been waiting for mine to ship from opt offroad since April 12th lol..

Thanks for all the feedback guys.

Will have to look into that Smittybilt some more. Wonder where I could mount it as it's bigger than the ARB dual.

I do have some Milwaukee tools and just picked up an impact, so air tools is more of a backup or just an option if absolutely needed.

The single ARB could be an option, but I do have a line on a dual that is in stock and I could go pick it up. So the convenience is there.

One other small thing to think about is if you mount the compressor inside the truck ive read it can be pretty loud. Only time you’d really activate it while your inside though would be for lockers.. not sure if that matters to you but thought it was worth a mention.

For what it's worth, I'm looking to buy a 1999 4Runner with a V6 and manual trans, but am running the ARB single on my Jeep with front and rear ARB lockers on a Dana 44 and trussed AMC 20 on my '85 Jeep Scrambler with 35" KM3s (used to run Krawlers) and 4.88 gears.

I have never felt the need for the ARB dual and the single saves me weight. I don't mind waiting a little longer to air up with the single. I plan to put that on the 4R when I finally find one.

This, I highly doubt you'd have the need for a pneumatic tool for any trail repair. Hell I almost never even use one in the garage, the only time I do is when I've screwed myself with empty batteries again However being able to air up wherever is absolute genius. We have a compressor on our CJ for this reason and it's a godsend at times. Very much recommend

I run an ARB CKMA12. It fills up my 35's from 8 PSI to 26 PSI in about 4 minutes a tire. The dual is nice but you can easily mount a single in the engine bay.

I wouldn't ever run Power Tank for lockers. If the line fails you'll dump that whole tank before you even realize the line is cut. Then you have no air source after repairing the line. So, no locker.

Speaking of the line. Use the one ARB supplies with the locker. They are super easy to repair if cut on the trail. Keep a few feet of it stashed in the rig, Then get some 6mm push connect couplings. 6MM is the size of the black ARB poly line. In less then 5 minutes you can cut out the broken section and splice in a new section. Since you went with a compressor instead of the PT you now also still have an air supply to run the locker.

Thanks again for all the feedback guys!!!

I think I'm going to go with the CMKA12 and mount it in the engine bay. Later down the line I might pick up a Powertank if I go to beadlocks with the monster valve, but keep the ARB for lockers and backup air source.

Get a power shot tank for your locker. Arb compressors suck and brake all the time

I looked at those, but $500 for the setup is more than the air compressor I just ordered.

I made my ‘PowerTank’ for ~200.

It’s super simple.

Thanks for the link! I'm looking at doing this down the road for filling my tires, but kinda nervous to run the Co2 for air lockers due to what's pointed out above.
