ARB Compressor Install with Upfitters

Deano Bronc

Yes, thank you for the tips. I may be helping @SlashRacer next month installing his. This will be helpful.

Hoping its this month!!!

Piece of cake. I tried to only highlight the stuff that wasn’t clearly documented in other videos or instructions. Let me know if you have any questions!

also, do you plan to pipe out of engine bay?

I’d like to pipe to rear hitch, but looking for a “go-by” and warm weather before that step!

There is a good video out there that helped me, so I’m mostly just adding stuff that I learned during the installation process. Thanks Pickens crew!


Here’s the kit, with the instructions. Everything is well made and the instructions are clear.

Fit the bracket to the upper shock mount. I found it easiest to insert in this direction, essentially from fender side towards the motor.

I have the upfitter, so don’t need the ARB switch, but the compressor mounting hardware is packaged with the switch – so don’t toss it!

I put a couple drops of locktite, just because of the vibrations that will be encountered.

I decided to mount the compressor with the wiring towards the fender (cleaner wiring and the air outlet more oriented towards the rear of the vehicle). I do plan to run a line to the rear hitch when it warms up a bit.

The ARB air fitting’s rubber cover will slide off so you can get a wrench and tighten it up with 19mm…

Now the electrical connections. I picked up some yellow (#10-12) ring terminals with ¼” hole for mounting to battery terminals. Also, a couple flange nuts to use the spare terminal points on the battery. Note there are two different sizes (M5x0.8 and M6x1.0). You could use the existing locations, but I figured I’d use the free ones. I soldered the terminals and put heat shrink on.

I used AUX 6 (far right) upfitter and splice/heat shrink to the purple wire from the ARB harness (only need this one wire as the ground is run separately to the battery. No significant current draw, this is just a control circuit and all the current comes directly from battery via the two #10 red wires. Secure wire harness with zip ties.

Testing.

I using the 4-tire Morrflate, I dropped all tires from 40 to 15psi in about 5 minutes. It seems like there is a ~2psi difference between the vehicle TPMS and the digital Morrflate. Thinking this is just the pressure drop in the lines, but could just be inaccuracies between the two measurements.

Airing back up was awesome. All four tires (285/70/r17) from 15 to 40 psi in 8 mins. Since all four tires are connected together, allowing it to sit for a few mins after airing up equalizes the pressure in the four tires.

Sounds like you liked the Morreflate? I have one on order as well hoping it will help save my back. :)

Huge fan of the Morrflate. The gang over there seems great.

The one thing I’m not 100% on is the style of chuck. With the recessed valve stems on the beadlock wheels, I went with the single tooth chuck and it seems a little sensitive to get locked in just right. when I was running this test one of the connections to the stem was not seated and the pressure started to drift away from the others. Took a little fussing to get it locked in, and then over the next few mins the pressures naturally equalized between the 4 tyres.

I’m not sure if the Standard locking chuck will fit mine, but I’ve heard it’s very tight.

which chuck did you order? Easy enough to change them out in the future, i suppose.

I’ve never seen this. It seems like a lot of setup to air up with 5 hoses. Is it really worth it? I have a co2 setup with one hose. It takes about 4 mind to blow 4 305s from 12 psi to 40. With one hose.

Shoresy

Sounds like you have a good setup!

I splurged a bit, after mooching off others air supply or tolerating crappy stuff…

I was around 8 mins from 15-40psi. Takes about 2 mins to get everything setup, and the Morrflate is great for airing (up and down) all 4 tires simultaneously to the exact same pressure.

Where did you run the wires from the compressor to the battery? I will be wiring mine up soon but want a near factory look. Not hard to do in this engine bay with the mess but ideas are good.

Just took a peek at Morrflate. Cool stuff. And they have adapters that allow you to use many different air compressors. I have a Vlair 88P that I feel no need to replace.

And any issues with using the shock mount for the bracket long term?
