Wj My WJ OBA II

Installed a Kilby Air Boss OBA system in the WJ Saturday. Took about 4 hours. Was a pretty straight forward install. Had to bend the ac line up and turn the radiator hose around to clear the top of the york ac. Got a little more work routing wires and tying up the air line to the back. Otherwise very happy with it.

I won the kit in a drawing I guess I entered a few months back. Forgot all about it until I got an email saying I won 2nd in the drawing. Thought I would sell it first but decided to see if it would fit in the WJ and it did.

So now I'm running the Kilby with the elec compressor back up. I mounted the Kilby tank in the spare tire well with the other OBA. Hooked both tanks together with a air line. Put a hose connector up on the brush guard for easy access. The Kilby is set for on=120 off=150 and the elec is set on=100 off=130. Fills the 5.5-6 gallon tank (2 combined) in about a minute to a minute and a half.

An added bonus is the diesel air horns vibrate the jeep with a 150psi pushing through them.

Wow that is pretty sweet! Nice install too! So the compressor runs directly off the motor? That's sick!

Yeah. We went back and forth in emails and they ended up sending me a kit for 99 and up wrangler with 4.0 and ac. The bracket replaced the stock alt bracket and bolted right up to the block. The alt bolted to the bottom of the bracket and the york to the top. Kit came w/everything including a new serp belt. When its goes on the Idle doesnt move at all. No noticeable drag on the engine.

When I went on there site, i did not see anything for a WJ so I was wondering what kit you got.

Is there an electric compressor and an engine driven compressor?

Meaning when the compressor turns on when the Jeep is idling it does seem to put much stress on the idle?

This kit is only the belt driven york. My other OBA that I have had on the jeep for several years now is 2 elec air compressors and a 4.5 Gal tank. The elec doesnt come on unless the york is over taxed. the york is supposed to put out around 4.5 cfm at idle. Should be plenty to keep the tanks full during tire inflating.

Dang that's a lot of hardware and space dedicated to two OBA systems. Looks like a pair of MV50s on your electric setup?

Not worried about that Radiator hose? lookin pretty pinched

Anyway to cut it put some stainless or blackiron pipe where that bends? to keep it from flatting out.

Yeah, but I dont use the wheel well anyways since I cant fit the spare in their and its a PITA to get to gear if I put it in the well and fill the cargo area up. I'll probably get rid of the elec air but no hurry right now. Yeas 2 mv50s. They work good with 4 Gal tank.

There is a good 1/2" clearance back and bottom for the rad hose, but i'll put a shield on the back where it comes close to york.
