On-board Air Compressor

[bdk]

I did a search but could not find a thread on this so if one exists please point me in the right direction.
First of all, let me make the disclaimer that I'm no where close to making this purchase, I have many upgrades planned that will take precedence over this but I have pretty well made decisions on what those items will be and how much they will cost and this is my next item to research. I like to plan my mods well in advance so hopefully everything works together and I don't waste money on something that won't integrate with future mods.

So I am looking for an on-Board air system that I can use to re-inflate all 4 of my 35" tires from around 20psi to 50 psi+ in a reasonable amount of time without overheating. I would like the ability to run air tools but that's not a necessity . Primary use for now would be airing up Atv tires and trailer tires up to 80 psi as both are prone to slow leaks as well as adjusting the truck tire pressure for drastic load changes. I may also put overload airbags on the truck at some point. I would prefer to mount the unit underbody and to have a quick connect at the rear of the truck so I can reach both the truck and trailer tires with a 25-30ft hose.

Here are my questions:
1) What brand is the best bang for the buck? Viair, ARB etc.
2) Large tank, small tank, or no tank?
3) Is it better to buy a full kit or purchase the pieces separate?
4) High CFM lower duty cycle or constant duty with lower CFM.
5) Best mounting location

Thanks in advance!

This PUMA is one of the most popular brands, and well reviewed. More so than Viair believe it or not.

Puma Industries PD1006 Air Compressor



I personally have two Viair 450p's.

If it helps in your decision, I don't think a tank really adds to speed. It does at first, but then the tank needs to refill, which slows things down. I'm now of the mindset that tankless, constant duty is better, unless you need or want to run air tools.

I am in favor of replacing the lines and chucks ( Coilhose Pneumatics CH15 Closed Lock-On Chuck, 1/4-Inch FPT - Lock it on the valve and let it inflate. ) anyways on all the kits for better ones. Makes it easier to mount and carry some hose to air your tires and maybe even a friends. All depends on your wants and desires.

Here's what I did with my new Mega Cab. I installed an ARB Twin compressor under the cab of the truck in a space that looks like it was made for the compressor to fit into, right between the fuel tank and the DEF tank (diesel truck). I do not remember if that same space was available on my Power Wagon. An air line was plumbed to the back of the bed, where a quick disconnect was installed. It is a clean simple system that works well. The ARB Twin compressor puts out over 6 CFM of air, so for airing up tires an air tank is not needed.

I've got two trucks, so I opted for a 20lb CO2 powertank instead.

I got puma. Very happy.

Thanks all, I'll have to look into the Puma's, the price seems reasonable. It sounds like I should just start with a good compressor for now and add a tank later if I decide I need it. I like the idea of the twin compressors too, seems like the high CFM would allow me to do what I need to fast enough I wont have worry about the duty cycle.

I dont know much about this subject yet, but I find it intriguing.

It would seem to me that tanks would almost be useless for just airing up tires... once the tank empty's after airing up part of the first tire then it is all on the compressor(s) anyway. But, for using air tools they would pretty much be needed.

Those PUMA ones, with the compressor and small tank, are they just a like a normal small compressor (looks identical to my Craftsman one) except they run on 12V? Where the hell would you put something like that? Or is it smaller than it looks in the pic?

Anything fit well on a 2014+? would like to do something reliable, not bed mounted. Have the 20 lb CO2 tank and the standard ARB compressor on my 2nd Gen, compressor is slow, CO2 is great but takes up a bunch of room.

I've been toiling over this mod for 2 yrs now. OBA vs portable. Compelling positions support both options. I've narrowed it down to Puma (I have the dims, but would like to see one in person), VIAIR 440p or 450p (higher CFM vs constant cycle @ lower CFM), or the ARB dual compressor OBA, w/ NO tank, plummed up similar to like Mopar has.

I have an earlier version of this compressor. It has worked without problem for years mounted upside down under my bed with a 4 gallon air tank. Generally takes about 3 minutes to air up a 35" tire from 25 psi to 55 psi
