Springs designed to counter the weight of the addition of bumper, winch, and sliders would complement the upgradable springs that are available for the rear. That would be nice.I’m thinking a longer spring is similar to the 20mm coil spacer, but usable for something? But my thoughts aren’t very coherent on this topic. I’m trying to educate myself and learn from the hive too.
Perhaps for ahc it isn’t relevant and spacers are better, I don’t know

A possible option to test lx spring rate:
Remove all pressure from the ahc system, place all vehicle weight on the springs, measure how much the springs compressed, divide that by the weight of the chassis

Won't the truck probably fall to the bump stops?
I think the springs are, partially, designed as a stop gap/safety measure to ensure that, even without ahc pressure, you can drive home. I think they’re designed to, in a borderline manner, support the car on their own.
May be not. I installed the LX570 rear springs on LX470, the rear end rode on bump stops without AHC. LX570 is heavier than LX470, the chance of a LX570 not on bump stops without AHC is slim.
Well it seems like the rabbit hole does indeed go deeper than we thought.
2014 LX - 60D91
2017 LX - 60F80
Same on the LC:

60D21
Can one of you forum losers show me your struts?
Something did change. The 2016+s are just so different... Never drove anything prior though so maybe your coils are indeed softer???
Or is it just a part number update? Cant be if it happened on both 200/201 with the redesigns.

What about these King KTRS-95? Stock height replacement 80 series rear coils. I can't find a spring rate though, slightly more than stock 80 I am guessing.I’m thinking a longer spring is similar to the 20mm coil spacer, but usable for something?

Depending on the year, the 80 rear springs seem to be in the 130 to 150 range.
If there was both a taller and slightly stiffer spring set i would probably be interested down the road.
Currently like my setup but ideally, the compression would continue past where my preload stack would limit travel upwards. Not that ill ever use it, but maybe one day

Resurrecting the thread once again! Have the distinct pleasure of taking ownership over an Inkas armored LX570 rated at B6 armoring level in the very near future. To my knowledge, these units come with AHC still working, with the only change being a spring swap to accommodate the heavier weight from armoring. Will probably end up emailing Inkas to confirm what changes to the suspension were made so that I can source these parts in the future when they are due for replacement but wanted to check in and see what other options exist out there.
Based on the thread, I understand LC200 springs (non-AHC) may be a viable alternative given the extra weight of the car; or would upgrading to OME springs with 270 and up spring rates be better?
Pasting here again the OME springs mentioned earlier in the thread:
OME 2720/2721 - 270-340
OME 2722 - 275
OME 2723 - 340
OME 2724 - 400
Am also aware Toyota Nestle offers dedicated armored AHC components, but can't seem to find a working link/part number for this unfortunately.

Confirming Inkas only swaps out coil springs on an LX570, rest of the suspension is stock.
Placing here the part numbers for everyone’s benefit:
| SUSPLX50020 | COIL SPRING LEXUS 1519 FRONT |
| SUSPLX50021 | COIL SPRING LEXUS 1519 REAR LEFT |
| SUSPLX50022 | COIL SPRING LEXUS 1519 REAR RIGHT |
Is there info on the spring constant or length? Google is silent on that part number
Sorry for the late revert.
Quite frustratingly, Inkas cannot disclose any specific information on these...would have to manually measure/calculate for these by myself, but am honestly unsure how.
You have to take the spring off, add mass to it, and measure how much it compresses. It sounds like easy, but in practice it’s not super easy to get the measurements. I was just idly curious.
