Torfab ARB twin compressor install

[Hayes]

Here are my first impressions of the Torfab mount for the ARB twin compressor:

Torfab has been great to work with. They shipped out the compressor and bracket, with the locker manifold soon to follow once it's back in stock at ARB.

The main bracket installed as advertised.
Relocating the various resistors, diagnostic plug, and other bits was a little less straight forward. I had to bend some small tabs, add a few washers, and tweak a few things, but in the end it is all relocated in a way that is satisfactory to me.
Mounting the compressor to the Torfab bracket was tight and fiddly. In the end I removed the two upper bracket bolts and flexed the mount away from the fender to make more room to install the compressor bolts. No big deal.
Not sure if it will have any impact, but I did add additional rubber washers on the bracket mounts for a little additional isolation of any compressor related vibration.
With everything tightened down, the compressor fits very snuggly in the location, with no wasted space whatsoever. Without the AHC pump, there's additional space that still might accommodate a moderately sized auxiliary battery or a small air tank.

For now the compressor will serve as on board air for tires and such, but I will eventually add air locker(s).
I will follow up when I finish the electrical connections.

Looks like a very nice fit!

I recently installed one in my LX as well. I really both the compressor itself as well as the bracket. I've got the switch temporarily mounted with some heavy duty velcro. I'm eventually going to install an SPOD and run the wiring for a full switch panel up into the sunglasses holder.

FWIW, I believe the instructions say to mount the compressor to the bracket once the bracket is installed. That didn't work for me. I ended up just mounting the compressor to the bracket and then installing the whole thing as a single unit. Much easier IMO.

Nice use of space

Wired up and all done.
I've got a quick connect air fitting hard mounted to my Slee front bumper for airing up tires. Works great. No air locker(s) yet, but I decided to get the wiring all done at once, so the air lockers will be plug and play as far as electrical goes. The switch on the dash will hopefully make that purchase happen sooner.
I used the ARB wiring harness, slightly modified to accept an OEM style compressor switch (sourced off eBay), and the OEM 80 series locker switch. Both are wired, but there's currently nothing plugged into the ARB solenoid plugs. The compressor switch looks and works great. Back-lit green matches the dash color, but is 50 times brighter than any other dash switch. It lights blue when active.
I used the ARB wiring diagram and the writeup on tlcfaq as guides.

I am curious what fittings and lines you gents are using to run the air back. I have a 2 gallon tank in the rear and have lines running to the rear and then back up to the front where a QD fitting sits on my ARB. The problem is that with the ARB twin sitting in the engine bay, it pulls hot air from the engine bay and therefore outputs heated air. I have had issues with blowing off those plastic "push to fit" fittings after airing up 8 35" tires.

How do you help dissipate the heat out from the manifold? I see the solution to this being either using a copper coiled line to help disappate heat or running some copper fittings instead of the plastic push to fit fittings i've been using.

I'm using brass NPT and barbs with hose clamps on all my fittings. Air line is 1/4" ID reinforced polyurethane hose from Harbor Freight. I haven't done anything yet other than switch it on to verify that it works. I don't doubt that it draws only hot air under the hood. I do doubt that copper line will dissipate heat quickly enough to cool the air. I think if the intake air temperature is too high, the solution would be routing the intake to somewhere other than the engine bay. I recall somebody on the forum routing theirs to the airbox. Don't know if I'd do that or not. Maybe just tap into the intake for the airbox, which is right next to the compressor.

In my situation it will cool the air sufficiently to not blow off anymore plastic fittings, or maybe I can do without those plastic fittings and just run some brass fittings off of it the manifold. The air is cooled when it runs to the back of the truck, into the tank and back to the front anyways.
