Some guy on Reddit posted about a Land Cruiser Prado 150 bracket for an ARB single fitting in the LR4, so I went ahead and said "I'm gonna do that." Finished it up yesterday. The brackets are KAON out of Australia and I got two, one for the compressor and the other for mounting the relay and switch. They were incredibly cheap for the quality, shipping was fast and more than reasonably priced. The favorable exchange rate was also great. I bought a knockoff ARB single for half the price of the ARB, because those are all Chinesium anyway.

Test fit, installed some rivnuts and mounted the bracket.

And because I don't take photos of every step, here it is all done.

And with everything all back together.

I removed more than half of the included harness; which includes provisions for front and rear locker switches and enough length to get the switch through the firewall and into your dashboard. I should have taken a pic of that, since I heat shrunk and wrapped everything all nice-nice.

All the connectors are Milton brass, and I bought a Flexzilla accordion air hose to use with it. The air chuck, blow gun, and tire gauge all live in a Shure mic bag with the hose in the driver's side third row storage compartment so they'll always be available. It's replacing a VIAIR 300P portable one, and even though it's 3/4 the size of the VIAIR unit, they fill the 255/60-19s from 15-32psi in the same amount of time; one minute and five seconds. I hated always throwing the VIAIR in the back and it taking up room, and then having to use the alligator clips for it on the battery. It's not fast, but it's fine and takes up almost no space under the hood. I've seen other installs where the compressor is mounted on the driver's side where many people mount a second battery, but I didn't want to use that spot because I want to install a second battery next summer.

Here's the link to bracket combo:

Looks good. That’s exactly the place I was planning on installing my ARB compressor before I abandoned the whole project. That mounting bracket is key.

maybe a dumb question, but I'm a coil spring guy so I'll ask anyway. Why not tap into the factory compressor and tank?

Everything I've read says the compressor is just not rated for that type of work/duty cycle. I don't know much more than that.

Yep, we hope the compressor just sits there and steps up when it's occasionally called on to do its job of providing compressed air for the air suspension.
