I have the Arb compressor. But it is really to small for airing up tires. It's meant for the lockers and thats about it. The best I know of are the Viair units. Some are big enough to run air tools if you want. You can see them at www.offroadoverstock.com . If you are just lookin for a great little portable unit that clips to your battery I bought one that works outstanding and cost about 60.00. There is a thread on here somewhere about it. If you are interested let me know and I will find it. I think Pepboys just had it on sale last week for 50.00 . If I remember right is a MV-50 model. I aired up 4 tires and leant it to someone else who almost finished before another guy did his 4 with one of the expensive ones.

I have the MV 50 compressor. It is a great/inexpensive unit. I can fill all four 31" tires from 12 psi to 35 psi in about 10 minutes total. Using a friend's Viair unit (the more expensive one) took 20 minutes to do 4 tires. The thing you've really got to look at on these units isn't pressure, but how much volume that they put out. 4-wheel parts sells the MV-50...I've seen them on sale in their ads for like $75. I waited around and got mine off ebay for $45.

I have 2 other friends with the same compressor, and we're all happy. One of them even has his hardwired and bolted up on the metal "tray" on the driver's side of the engine compartment.

That's pretty nice in that it comes with a tank. What are the outter dimensions of the unit? My only issue with it would be how much room it takes up. You may be able to hard mount it to one of your rear fenderwells. I dunno... I like the fact that mine takes up so little room

I was actually thinking of hard woring a compressor in then sealing the front bumper and using that as my tank..nice part is that it's all under hood...only drawback is that then your front bumper has to be airtight..and the welds have to be strong enough to hold pressure..Just my

I would like to mount it under the jeep, but high enough to stay out of harms way, possibly getting lockers in the future, but havn't thought about it too deeply yet. I also may want one with a tank. Again the dimensions on that puma would be helpful. Thanks

That's the direction I intend to go. Pull a York at the salvage yard, buy the Kilby kit, mount a 2.5 gallon tank up between the frame rails. It will also power a weapons-grade air horn.

I'm looking into a tank too, maybe purchasing soon. When I get it, next question will be how much to air down with different terrain? I have 33x12.5 trXus mud terrains on. Thanks in advance!

Jeepnut, on the airing down question i would start around 15 psi and go as far as 10 psi, the only problem you may have with going 10 or lower is popping the tire off the rim. I ran 285-75 -16 's on my WJ (33-12.50) about, and i ran those about 12-13 psi and had good results. I would gather that you have around 30psi in them for the street, so by dropping down to 15 psi you will have a good bite and can still do minimal street driving if you had to. My best idea is play around with a few setting and see which one fits you and your driving style the best. I hope this little bit of information helps.
