Great info, thanks for your help! After dialing down my sensor lift from max height to mid-way, my front pressures were low. After adjusting t-bars again I am at 6.9 front and 6.9 rear. This is with a full tank of gas, no passengers, on level ground. I have not unplugged the temp sensor for rear pressures, as I heard it was hit or miss. I am thinking the rear 30mm spacers combined with my King springs could get me to the proper rear pressures from my current 6.9. Thoughts or ideas? I will definitely look into the LC t-bars also but I am a little nervous as my driver side t-bar adjustment is a real pain to turn now. It doesn't appear to be cross-threaded but it is not easy to turn like the passenger side.Spacer do make a big difference with Kings. Much more so than with stock AHC coils. If you'd like to max sensor lift. I would then add either 20mm or 30mm spacer, depending on your weight and height you'd like. Note: You can stack up to 2 spacer, according to manufacture.
I'd would consider LC T-bars, if you've added weight like with winch and skids with that bumper. LC T-bars may not let you drop to low, if not enough front end weight at stock height. With just an iron front bumper and stock height (~19 3/8"), LC bars likely not needed.
You'll get benefits from this set up.
1) With your new globes, you should be able to dial in frt Mpa as low as you like 6.9Mpa, or even lower and not max the T-bars. Rear pressure, depending on weight and which spacer. You should be able to get ~6Mpa (before adding gear & people).
2) Reducing the pressure, by shift more weight to coils and T-bars. Will save AHC for when needed.
3) If AHC failure happens on the trail, you'll not drop to the rocks w/LC t-bars. (Carry a 30MM socket in your tool kit).
Note:
We set pressure and height, with full tank of gas and vehicle empty (no people or gear). You can play around a bit loading gear and checking pressure. Some do like to set pressure a bit on low side, unloaded. So that when loaded pressure aren't to high. It get into feel of the ride.
Rig is heavy for sure, build thread is: Cream Puff Build Thread - https://forum.ih8mud.com/threads/cream-puff-build-thread.1011395/
ARB front with winch, BIOR rear with tire carrier and hi-lift. Also have a spare in stock location for my trailer. Fridge stays in full-time and looking at doing a single drawer on driver side. So yeah, I got all the weight! That said I don't really need a max sensor lift, so moving that down a bit is fine.
