My ARB twin compressor on board air setup

[DMopar97]

I probably could have gotten the ARB twin piston compressor to fit in the ABS tray, but I wasn't overly happy with the fit, and since my 2005 has all this room on the fender from moving the charcoal canister to the passenger rear fender, I figured I'd make a bracket to cleanly mount the compressor on my drivers side wheel well.

I'm still fine tuning it, and waiting for some parts to show up (3 pin wiring harness plug for the arb compressor, a different switch, and a different air chuck), but this is the basic concept I'm going with. I used 5mm bolts, which all fit through existing holes in the fender. I used some old valve stems that I cut up to use for rubber vibration isolators. I added some zip tie holes, and some holes for snapping in wiring harness clips I had to remove to make room. I didn't have to relocate anything else. I orginally made the first iteration from 18g mostly because it is cheaper, and I thought I'd be remaking it with thicker sheet metal, but honestly I don't think it needs it. I'm sticking with 18g for my final version.

I know many people like having the switch on their dash, and/or don't like having to open their hood to air up, but that wasn't my philosophy or goal. I like simple, so I wanted the switch and air chuck right next to the compressor. But nothing here prevents me from adding a manifold, or moving the switch or air chuck later on. I'm only using this for tire inflation. No air tools, no ARB lockers.

P.S. For those digging into the picture details, there's a couple of different versions of the bracket shown here, some with some minor flaws. When I get my delivery from brown santa, I'll pull the whole thing back apart, cut out a final version, paint, etc.

For my air hose, I hate standing half hunched over to air up tires, holding the handle down. I usually end up putting a slideable zip tie on the handle of the inflator valve handle. So I abandoned a traditional inflator chuck, and made my own with a ball valve. I used generic hose barb fittings where applicable (except for the flexzilla fitting that came with my donor 1/4" air hose.). I used oetiker clamps to secure the hose to the barb. I threw some heat shrink over the top of the oetiker clamp to soften the sharp edges. I'm looking for a nice glow in the dark air gauge to replace this cheap one.

Yes I'm aware that if I am not paying attention I could over inflate. I added a little bleeder valve button for fine tuning without having to disconnect from the compressor. I may consider making it do two tires simultaneously, but I'd have to switch to a different chuck, since the lightning chucks are all open flow (or add another valve which I'd rather not do). I really like the lightning chucks, so I probably won't go to dual tires right away. and I definitely 100% won't go to 4 tires simultaneously, I think that's a waste of space. Plus I'd have to start hanging out with JK guys

The hose pictured here is a test hose I built for use in my shop to test the concept out, I'll obviously build a longer one for the trail that can reach all 4 tires.

I installed a distribution block I got from McMaster Carr I have an air inlet with shutoff valve a front and rear line leading to quick disconnect fittings front and rear. I have a tee hose that clips onto the valve stems of two tires. I turn on the compressor after pumping I shut off the inlet valve to check the pressure then turn back on if more pressure is needed. I can also hook it up and open the bleed valve to deflate the tires.
