They are pretty tough to locate nowadays! I've been looking at these ones which say in the Description:
"LEXUS LX470 UZJ100R - 4WD 1998 - 2006"
And confusingly it differs from their "Compatibility" section, where 2007 and even 2008 is included. To try to get to the bottom of this discrepancy I've been back and forth messaging with the company, but the person I'm speaking with "confirmed" they don't have any King springs compatible with a 2007 AHC LX470.

And actually King Springs seem to say the same on their website: LEXUS LX470 UZJ100R - 4WD 1998 - 2006 - Fit your Vehicle - King Springs Automotive Aftermarket Springs - https://kingsprings.com.au/catalogue/vehicle/526/lexus-lx470-uzj100r-4wd-1998-2006

Thanks @gwrobertson89 - this is interesting.
I am going to keep my kings on the truck, they seem to be working normally, will follow up if any issues.
Edit to add- I do not have extra AHC lift, system is working within factory parameters.

Thanks all! Some background context and additional updates - somebody from King Springworks got back to me confirming all I need to do is ensure the product code is KTRS-79 and they are compatible with the 2007 regardless of what the vendor is saying.
The context:
I've just added steel front & rear bumpers, and have a roof rack on the way. Call it 300 pounds of permanent extra weight. My next step will be to do the Techstream AHC diagnostics to see how things are looking pressure-wise. If they are high, I'll likely add King or LC springs and crank the torsion bar as necessary to get them to ideal levels. Will likely do the AHC speed sensor override switch (just so I can drive ever-so-slightly faster than 20mph on the beach in High).
Although I'd love to do some AHC lift work, I'm scared things could get messed up down there eventually and become very expensive to remediate. A valuable but overwhelming amount of info and perspectives in these threads about AHC lifts (e.g. sway-a-way bars / links / AHC shock spacers / rear dif drop / new torsion bars / spring spacers etc etc etc).

Finally got around to installing the Japan 4x4 spacers I have had sitting around for well over a year. Fabbed a rear bracket using 3/4in x 5in piece of aluminum. Now just need to cross level and check pressures on tech stream.
Just wanted to provide a reference point for anyone looking to do an AHC spacer lift in the future.
Checked my pressures and dialed in the front at 6.7 with a full tank. I might crank the t bars a little more to get to 6.5. Before the lift my rear pressure was always a little high at 6.6, but still within upper end of spec. After the lift I’m at 8.6 in the rear so am going to have to upgrade from the king springs to LC100 springs. I don’t think the 30mm space will bump me down enough to be in spec.
I’m running ADGU drawers that are usually mostly full, white knuckle dom sliders, dissent skids, dissent roof rack, and GFC RTT.
Globes are OEM and new. I replaced them in the last year. Fluid has been changed at least 3 times in the past 100k miles.
Fully loaded with camping gear, dogs, and two people I’m coming in at about 7,300 lbs.
If anyone has any other spring ideas let me know. I believe lx450 springs were an upgrade option, but they have been discontinued by Toyota.

I installed the oem LC100 springs over the holiday weekend. Mostly unloaded and with 1/4 tank of gas I’m at 5.4 in the rear and 6.4 in the front. Rides great.

I still love my setup. 80 springs with spacers, loaded with bumpers, sliders, winch, roof rack, swing outs, put the tent on a trailer, sensor lift, almost 35” tires, still goes LNH, reindexed torsion bars, and suspension still softens and firms as needed. Just another experience…. Hope it helps someone.
