Just realized this was your video, not just linking to it. Nice work and good review, i may pick one up, price is decent!

Thanks. I fully expected that thing to overheat and cut off and kill my entire battery (which came out of a tool, not off the charger) when you get over a 35” tire you really get out of small compressor territory. Even the ARB compressor that is vehicle 12v powered takes 3 minutes too air up a 33” from 10-30 psi

I was very pleasantly surprised by it. Of course it only makes sense to buy one if you already have that battery platform. Milwaukee I’m sure is just as good. I’ve used a Milwaukee one on the trail that I borrowed and it was pretty good but it’s been a while.

I ordered one of these compressors today. Just happened to get an Amazon gift card from work for my birthday

I love my ARB twin. The single is very nice too. Especially if you are going to hard mount it. I am very surprised by my modded Smittybilt. It really flows the air.

I have too many compressors. I have convinced myself I don't need the Milwaukee compressor. I think....

I agree, I run a arb twin in the PW and a single in the 4runner and they both do quite well. One thing I noticed is there is a lot of water build up in the lines under heavy use. I may put a water separator in-inline at some point (I should have done it when i first installed it)

I’m guessing that probably has to do with your environment being high humidity. I haven’t noticed it moisture build up, but I’m in dry Colorado

Also, it doesn’t really matter if you aren’t running air tools off it where the moisture would result in rust. I’m just using mine to fill tires…

I have the arb single, been happy with it. Bought it “used” on Craigslist a few years ago for my Chevy, but finally got to mounting it in my Ram this past spring. Might not be *as* fast as the twin, but it seems to fill my 35s pretty quickly.

I have noticed moisture too. Unavoidable when compressing air. The inline water separator might be a good idea. Especially in systems with a tank that could rust or corrode. Right now I just drain the tank.

I haven’t tackled this project yet, but the system I’m eyeing at the moment is this one. The tank is approx 6” diameter so it should tuck under the truck nicely, probably outboard of the frame under the cab. I will also mount the compressor under the truck or inside the topper, undecided yet. I will route an air line with quick connect on the rear and the front of the truck.

it claims filling a 37” with a full tank in 4 mins.

LOL.....I have that in my Amazon list too. Probably depend on whether I get the Decked system or not. If i get Decked I can store my portable in it.

This kit went up $200 it is now around $600. That’s why I pulled the trigger on the ARB hi output single @$308. I’ll build my system around that.

Funny to see that. I did get the portable and it is in my decked system. LOL Although I am going to put my Sh*tybilt in the drawers for everyday carry and just pull out the ARB for trips where I will air down all the tires.

The arb twin portable is a beast, I was running that for the longest time before I decided to go hard mount (I got tired of lifting in and out of the rigs, it took up a bit of cargo space, and was worried about theft). I did mod mine to allow for “universal connection” it makes hooking up quick and no need to pop the hood.

Yes, that thing is a beast to move around. I have probably used it more on other Jeeps than my own LOL. I thought about changing the connector out to something like you did. I would have to do it for both the Jeep and the truck. I like how you made an adaptor to still use the alligator clips.

Thanks, yeah I swapped out the clips for a nocco set (a little better quality than the ones that arb included). The alligators are for redundancy or if someone needed to borrow the compressor. Another nice thing about having an anderson plug, is i also modded a jumper cable, so if i need to jump I just plug into mine and clip on to another vehicle. I used welding cable direct from battery to the plug, so it satisfies all my power needs.
 
Anyone know of a company that makes a bracket to mount the 12v ARB twin into a cummins truck? I might go this route if i cannot figure out how to make my factory air system work for airing up tires.
 
I don't think you want tap the factory air setup. I've always been told the compressor won't hold up to that kind of use. I doubt it would have the duty cycle to air up one tire and absolutely not four.

I imagine that's correct. Just seems redundant to add another compressor to this truck! Would be REALLY nice to have though in the desert when we need to air up tires. Ugh....

It's not that, the factory system is sealed and is 100% nitrogen.

I believe that is only true for the 1500s, but am not 100% sure. My 2500 was supposedly initially filled with nitrogen, then the compressor can make up small amounts of air as needed. It has an air intake open to the atmosphere between the cab and bed. I'm sure the 3500s are probably setup the same way.

Once you experience onboard air, it's hard not to put it on every truck you get. It's allowed me to quickly plug a tire, more than once, to get me off the side of the road instead of changing the tire there. And to add to the misery, all my roadside flats seem to happen in the dark...
