Springs to help rear AHC Pressure (10 Viewers)

[01BluLX]

Is there a thread or any collection of information that explains options for rear springs to help high rear AHC pressures? I've looked over the ones that I can find, but there doesn't seem to be a real consensus on how much each option lowers the pressure. My rear pressure is a little high at 7.4. I have drawers with tools/camping gear, otherwise stock. 265k on my truck, and the rear coils are original as far as I know. I have globes on order, although that won't change the pressures from my understanding.

I still need to adjust my torsion bars to get the front in spec, but I'm just looking for some input on what to do with the rear. Spacers, OEM LX coils, Kings, AHC LC coils, non-AHC LC coils? Too many options...

I can't answer your question, but the front will take load off of the rear. Get the front right before you make decisions about the rear.

Also, (and I'm just thinking out loud) it's pretty typical to need to replace springs on a 20+ year old car of any kind. I wonder how many people have gone to heavier springs, when their root problem was actually worn out springs. That said, I have no problem getting my '99 into spec pressure.

King and 30mm rear spring spacers. Adjust rear height sensor to get desired pressure, which could be stock or slightly lower. Then adjust front end height to compliment rear height. Lastly, adjust t-bars to get proper front pressure.

From what I've been reading the Kings sound like they might be too stiff, not sure though. Do you have personal experience with them?
I worry that if I went that route, my pressure would drop too low and end up with a bouncy ride... but that can be resolved by adjusting the height sensor?

No, I don't have the Kings personally but people sometimes say they aren't enough. It's the next spring up, there is no in-between except maybe an LX570 spring. In any case, no doubt, you can get your rear pressure in spec with them, it's just a matter of adjusting the rear height sensor (and hence ride height). If you are inflexible about ride height, then it'll get a little more tricky and you'll need various spring spacer/trim packers on hand to fine tune.

You can even drop the rear ride height now and get the rear pressure in spec. If happy with the ride quality/load capacity and only unhappy about the drop in ride height, you can just get 30mm spacers... and again adjust rear ride height 30mm higher and the pressure will be in spec.
