Air Compressors - Best type to keep in LC?

The CATuned kit looks interesting. Like the idea of a permanent solution vs. something I have to hook up when wanted. I had an ARB mounted under hood on my LR4 and I used it way more than I ever thought I would.

One question I have is why wasn't the air fitting designed to aim towards the side of the vehicle instead of towards the center of the engine? Seems a little awkward.

Also not sure about how the wiring is run. I suppose that's a more minor quibble, though.

I have a new single motor ARB that I was messing with this past weekend. Thought about mounting it in the spot where the stock jack goes (and obviously moving that elsewhere). Would require the fabrication of a bracket that insets the compressor more than the jack. This may not be a good idea, however. The ARB compressor can get a little hot so mounting it somewhere with suboptimal ventilation could be asking for problems.

Then again, the CA Tuned kit has the ECU's mounted right on the dual compressor. Maybe the dual doesn't get as hot as the single?

If you can fab a mount for the jack area, there more than enough room in the engine compartment (search for EOD's Guy Ride) for mount I fab'd on my install.

I like your setup. If I decide to mount mine in the engine, I may go that route.

That said, the space under the hood looks pretty limited. Where you have your compressor mounted is one of the very few free spaces in the engine compartment, and a spot I've seen others (Dissent Offroad) use for their switchpro mount. I was thinking of going that route. That, and I think a compressor somewhere in the back may be more handy for me.

Thinking about mounting it in the jack position a little more, I know there's a factory Lexus GX550 accessory that would mount a compressor in the compartment where the battery is on the 250. So, apparently Toyota isn't too concerned about heat (unless they have a special compressor that runs cooler).

There is a couple of promising mounting spaces......... Just forward of the battery, where the 3rd row arm rest is, easy access through the cup holder and it appears the relays and fuses that are mounted in that area might be relocated for a little more space if needed.

Rearward of the jack cradle on the bottom, there also seems to be a fair amount of space.

This cleared up a ton for me. It is interesting as it seems there are different styles of wiring harness being sent from CA tuned. My power harness has a positive pigtail on the compressor side to add tie in the ignition switch wire(red/yellow) eliminating the need for extra wire.

I was one of the first orders out and I think they made some adjustments to make things easier.

Thank you so much for this video, respectfully CATuned original video was missing a lot of installation information. Things as simple as unclipping some hose/wire manifolds, cutting/pulling back some black electrical tape (which they did in the video, just didn't show it, and of course the biggest problem was the wiring. Great product, wish they re-made the video though.

I just did an installation of the CA tuned on board ARB compressor. Just by going by the videos available it took me and my friend about three hours to install. piece of cake. Bought a four tire air up/down kit to go with it. Air down my tires to about 15 psi and this thing aired them up to 33 in about three minutes. Super happy with this install.

I know that I could’ve built the air hose kit myself, but it would not have been that much cheaper after I had selected better quality parts to use. Plus the fact they’re given a lifetime warranty on hoses and you get a carrying case I think I made out pretty good

I’m leaning toward the Viair 88p to leave in the cruiser. Rated at 2CFM, not amazing but still a lot better than my portable ryobi inflator. It looks pretty small and compact for something I’m not going to use all that often. I looked at some bigger more powerful options (some with multiple tire inflation), but the overall size and bulk is my main concern.

I’m looking at the viair 88p as well. Did you get it, do you like it? Thanks

Hi TrailWhale, still in the market, but have not purchased it. Thanks for sharing with us.

I ended up getting a bigger multi-tire system. The EZ Flate MESA with their hyperflex 4-tire inflator/deflator. It's kinda the exact same thing as morrflate and some other brands. It just happened to have the biggest discount when I bought it.

In the end, I kinda regret it since I use it so rarely, I'd probably rather have something much smaller. The hyperflex hose system is super cool though!

Yes, amazon for $80. Happy with it although I haven’t had to use it yet. Lives in the cargo area now.

I recently got the DeWalt 20V Max air compressor (DCC020IB). It comes with a 12V plug, can be used the DeWalt 20V Max batteries (which I already had on hand from my cordless drill), or you can purchase an AC power supply. However, the AC power supply is ~$50 for the DeWalt branded one. The bare tool was less than $100.

Used it for the first time this weekend. I'm still on the 1958 OE Geolandars, but I aired them down to 25 psi for the Main Divide Trail in Cleveland National Forest just to smooth out the ride a bit. We went in at Silverado Trail Head, went up and over Santiago Peak, then came down the Indian Truck Trail. At the Indian Trail Head, it aired the tires back up from ~27psi to 33psi in 9min 5sec on my 20V battery only. Didn't even feel warm to the touch after. I was pretty happy with the performance. Maybe when I have bigger tires and it has to move greater volumes of air I might need something more.

I really liked the pressure setting and auto shut-off. And the hose threads onto the valve stem, so you can just hit start and let it go until it shuts off. Reasonably quiet too. At some point, especially once I pick up the power supply, a little carrying case or bag would be nice, but otherwise no complaints.

This is the one I have. C.A.S.E. - Portable Air Compressor

RideWithYanu · Jul 14, 2025

I went with the MorrFlate PSI Pro TenSix and their quad hose system because, while it’s definitely a big expense, it’s a huge quality-of-life upgrade if you’re frequently airing up or down. It automatically balances pressure across all four tires whether you’re airing down or airing up; this is even faster with my Apex RPV stems, which let me dump air quickly. The compressor itself has a set-and-forget target PSI feature; I can hook everything up and then sit back and relax for about 4 minutes while it runs all 4 tires from around 8–15 PSI back up to 38 PSI without needing to babysit it. My next project will be to permanently install SAE connection cables from the battery into the factory bottle jack compartment; I’ll also modify the compressor’s alligator clip power supply to SAE quick connects to make setup even simpler and faster.

I was going to go with the ARB twin, but decided the portability of the Morrflate was better for me than a permanent install.

Where do you connect the alligator clips of your compressor in the LC? Just off of the battery terminals in the cargo area?
