I am running the VIAIR 450C constant duty kit with 2.5 gallon tank and absolutely love it. I have aired 12 tires sequentially one after the next from 15psi to 35psi with no issues what so ever. I have a buddy who is running the VIAIR HD kit with no tank and his compressor hits thermal overload after 5 tires.

 

Here are a few pictures of my OBA.

 

Lucky SOB I wish I could have gotten a bit of a break on some of the parts.

 

I run a single Air-Zenith compressor behind my rear seats, just in front of my Tuffy security deck partition. It pumps up 35s with no problem at all. They are pricey, though!

I'm very interested in getting oba on my JK . I like thegoat's setup. Going to price it out and start collecting parts.

Thanks for all the info

 

Any air tank? Out just the compressor?

I have the viair 400C kit with the under hood mount from jeepswag.

I have been happy with it. I think it was about $250-300 for the compressor, hose, and the mount.

It takes me right at 2.5 minutes to air my 35's up from 10-12psi to 28 psi.

 

damn you can get dual viar 444cs and a 5 gallon tank with regulators and all that for $330 all you need is hose.

 

Mine did hold air quite long time. Have a slow leak in my check valve now. It will leak down from 200 psi to about 100 in 5 days last time I checked it.
