Just get 30mm spacers.

I have a 2000 lx470 with 240k miles and functioning AHC. My rear pressure is a bit high. Should I just get spacers (30mm?) or should I replace coils with LC coils. I have heard LC coils are firmer than lx470 coils. Or should I get new coils and spacers? Also planning to put in airlift 1000 airbags for rare times when I tow trailer.
Thanks for the help with this. I have looked into spacers and the airlift 1000 airbag (for when I tow). It seems that the spacers sit on top of the existing springs and so I am wondering how one routes the inflation hose for the airbags as they exit the top of the airbag and are usually routed out the top of the spring. Should one just turn the airbag upside down and route inflation hose out the bottom of the spring? Is that possible?
The spacers are hollow rings. No need to change your airbag plumbing.Thanks for the help with this. I have looked into spacers and the airlift 1000 airbag (for when I tow).

@suprarx7nut @GTV So adding spacers would seem to be the cheaper option than replacing the old Lexus springs with new Lexus springs, but would replacing the springs give a smoother ride than just adding spacers to the old springs? I was surprised that @MarkTR replaced the springs and was still getting high rear pressure, and that he decided spacers were also needed. @MarkTR are you running a mostly stock truck, or do you have added weight in the rear? I'm curious how your truck turns out with new springs and spacers.
Stock bumper, but Trekboxx fully loaded and pioneer platform/rtt. Will be adding sliders soon.Are you running aftermarket bumpers or a AHC lift? I have the same springs with a aftermarket rear bumper and AHC stock height and I'm at 5.4

Any advantage to longer springs with a higher rate (ie 100 non-AHC springs) vs just adding 30mm spacer to the kings?
Yes, agreed. You can up the preload with the spacers, but if you want a more dynamic/firm response the higher spring rate off that precise neutral point is what you need to chase. AHC keeps the neutral height spring rate in a pretty narrow range (assuming you're in spec) - but only at that one exact static height point. The spring rate is then largely determined by the mechanical spring as the suspension moves up and down. I haven't played with the non-AHC springs, but my assumption is that the spacer approach is more comfy, but with some roll and float. And then the stiffer mechanical approach should yield a firmer and more stout dynamic feel at the expense of limited comfort. That said, I imagine a heavy 100 with AHC on stiff springs is still quite a bit more comfortable than your typical conventional suspension setup so it's all relative.I've been asking myself the same question.
In addition to drawers and a heavy bike/rack, I've gained 250lbs to my roof over the last month. The tail now wags a bit under cornering and turning to sport doesn't do anything to mitigate it. It feels exactly like what it does when the coils are too light. I was previously thinking I could spacer it more (currently 35mm) but a spacer is only going to accommodate for static pressures. Spacers are fine to a point but a heavier spring is eventually going to be needed to control weight dynamically. I'm beyond that point.
The common denominator on a few pogo stick cases that I have read on this forum is non OEM globes.But it's worth mentioning again what @suprarx7nut said, some folks are seeing pogo stick with Kings and their AHC. No common denominator identified as of yet but I'm not getting that behavior at all.
Do you have a reference for this by chance? Concerning the life of the "shocks?"1. With AHC you never change shocks. The AHC components that look like shocks (and confusingly which are labeled as shocks in the parts diagrams) are really just rams. The "shocks" from a functional perspective in AHC are the globes (AKA gas chambers). The AHC rams/shocks almost never fail and are generally considered lifetime components.
