It looks like you can get it at Bell Lexus for $1,281. I wonder how the installation would work. In any case, I ended up with the portable ARB Dual Compressor which is less expensive than this setup. Thanks for providing the part number.
 
I've talk to lots of folks around the built in versus portable - several whom are hard core over-landing people. If you have an OT model - a basic $500 ARB unit w/no tank will easily handle the 33" stock tires without issue. You can go big boy on the compressor - but the basic will handle what we all need - especially when you consider how often it will be used.

I realize having a built-in is convenient and would take up less space, but I agree with you 100% - for 1/2 the price of the built-in (or less) I can get a Thor's Lightning compressor that automatically stops at whatever pressure you set AND have the kit to inflate/deflate all 4 tires at once. Why wouldn't I go with ARB or Thor's Lightning or some other well-built aftermarket compressor?
 
I've had ARB compressors in two previous trucks. It's cool and convenient but they do take up space....and the compressors get HOT. Both previous trucks were Land Rover Discoveries (1996 and 2004). The compressors were mounted in the back cubbies which provide a ton of storage space. I'd pile soft stuff like blankets, hats, gloves, etc. on top of the compressor but you have to dig that stuff out when you use the compressor and then you can't pile stuff back in the cubby for a while because the compressor gets so hot. I'll be picking up a portable ARB or comparable unit when I get around to it. Also make sure that your portable unit uses universal air fittings. I picked up a Smittybuilt portable unit for my 2013 Land Rover LR4 and I was surprised to find out that it used proprietary fittings, which pretty much made it worthless. I returned it. The Smittybuilt units are actually pretty good, though, so you could always replace all the fittings with universal ones. I just didn't feel like dealing with it at the time.

The heat is a big issue - I went with the basic ARB tankless in a small utility box. I wanted to use a converter with the same Amp req, then plug it into the rear outlet on the GX - but after talking with ARB they want it connected directly to the battery for some reason.

Regardless - it stays out of the car until I need it - and I can’t see using it more than a few times per year.
 
I’m trying out the Fanttik X9 Ultra for an upcoming trip to Death Valley. I got it at Amazon during Black Friday for $99 so no big loss if it doesn’t work out.

I have tried airing up all four tires to 35 from 20 and it worked pretty well. I have an ARB Dual as backup just in case.
 
Ordered by Overtrail+ about 10 days ago.....
On the Lexus website they advertise that this trim level comes with an on board air compressor.
Thoughts?

There are a lot of wild pigs in south GA :) Overlander will do great on some of those back trails....
But... has anyone seen / heard about the air compressor as a feature?

Yes, it's an advertised feature for 2025. Nothing in the new owners manual about it though. I guess I'll find out about it when it arrives in a few weeks.
 
I would consider the on board setup. Yes it's twice as much but as noted if it's the basic ARB setup it will run for years and knowing it is there to help others when I don't pack mine. The heat is a real thing. I have a Viair bag compressor for my club wheeling and used it in our 80 when overlanding and it will burn you if touched after use. Repacking is a thing so it stays in its bag open and uncovered until cool. A built in unit would be very nice. Looking for a new owner of a 2025 OT to report on it.
