Someone school me on OBA systems

What do I need and what's the best/ cheapest way to do it. I want to use if for a train horn and airing up on the trails.

Thanks in advance!

There's always the electric route. There's a vendor that pops up every now and again "OnboardAir" and they have lots of viable electric packages. I pieced mine together by starting with a smittybilt 2871 compressor (it's warrantied) and built around it piece by piece. It's a standalone model for tires and if you want air horns later it will provide the air for that as well. I should have done a cheap build thread on mine only because it was budget minded but that time has passed. You can PM me if you want a parts list, I'll put one together.

By the way, I love how every time someone mentions Smittybilt, they follow that with a justification... Hahaha I've heard a lot of bad but so far have been pleased with my smittybilt purchases. CRES, soft top, and soon front bumper.

There's a reason for the justification. I've had to use the warranty once on this item and made an exchange just two or three months after making the initial purchase. Since then, it has filled up almost everyone's tires after every run since the beginning of this year.

Electric is usually easier to setup, but you typically don't get the same performance as say an engine driven compressor or a CO2 tank. The CO2 tanks are very nice, but then you need to worry about keeping the tank full. That's about the only downside I've noticed so far; they're very fast, which makes filling up pretty painless. Personally I like the engine driven compressors, and will be ditching the CO2 tank, or just using it as a backup once I finally get my York setup pieced together. Either the Sanden or York compressors work great for OBA systems. I used the Sanden compressor in my last Jeep, and it worked great; I had no complaints whatsoever. This Jeep is a little nicer so I want to keep the A/C, hence the York compressor.

The engine driven compressors are definitely the nicest in my opinion, but depending on which route you take they're usually more expensive to do. Search a bit for York and Sanden OBA writeups and you'll get an idea of what they entail.

I just bought the MV50 compressor off Amazon for under $60.

It's really just for tires though. But I've seen people mount these in their Jeeps easily. For me, since I have several cars, I'm keeping it portable.

I think I will go the electric route to kep it as simple as possible. And who knows I may want to add a/c later one as well.

I haven't given up on this! Any more ideas. I'm hoping to start piecing this together after Christmas.

Im using an engine driven york myself. If u do some looking around u can sometimes put together a nice OBA system. Ive bought pieces from individuals as well as places such as Kilby. Snatch a york or sanden from a junk yard. A lot of volvos used york style compressors and u can sometimes pick them up cheap.

I think I'm gonna go with a 12 volt system instead of the engine driven. For my use it will end up saving me money I think.

Around here you can pick up a stock Sanden compressor for around 60 bucks.
Cheaper in the winter.
The stock mount is already there to bolt it up. You will have to pick up another pulley and different belt.
Instead of a oiler I went this way.http://www.grungle.com/endlessair.html
You will still need a dryer/filter, pressure switch, pop off valve and a tank.
Electric or engine driven you are still going to spend in the neighborhood of $100 to $200.
I could see where a electric would be a easier install though.

93 YJ SOA 2" springs front, XJ springs rear w/main leaf added, High pinon 9 inch rear detroit locker front Dana 44 ARB 4.56 Gears, 36 inch Irok tires too much to list.

I have a Viair system (sold as a "JK" kit since it comes with a bracket for mounting to my crossmember in between the radiator fan and the motor, but thats it) If you have room, its pretty nice to have dual compressors mounted on a tank. Fills to 140 psi in like 20 seconds!

YOU CAN'T HANDLE THE TRUTH!
