It appears that the coils for ahc changed in 2016.
Does anyone know what was changed? Are they slightly uprated?

Difference between ahc pre and post 2015?

It appears rhat the front strut is the same part between the 2015 and 2016…though the coil the strut resides in is a different part.
Would someone with a 2016 care to measure the thickness of their coils? I suspect Toyota/Lexus may have increased the spring rate in 2016…those coils may, if that is the case, be an “easy button” uprated capacity coil for pre 2016 lx570’s

The rear coils stayed the same.
It appears the only change in ahc from 2015-2016 was a difference in the front coil.
So if someone with a 2016+ would be so kind as to measure the diameter of one of their front coils, that would be great…might be the case that the uprated springs for the front that we thought weren’t available on the market actually are available…from Lexus.

The front coil on a 2011 appears to be 16mm thick.
You know you can edit your posts, right? That way you can keep the info organized and save people time reading.
I doubt you get a lot of upgraded capacity by switching OEM to OEM coils only in the front. Why are you looking to do this replacement?

It’s looking like one of my coils has weakened over time and could be causing the vehicle to lean.
I’m looking for replacement coils. Brand new 2021 coils are easy to find and cheap as take offs.
Brand new coils that are cheap take offs from 2015 and older aren’t available anymore unfortunately.
I suggest you go with the available part!
If they are uprated I'll be putting a set on my LX when I get around to doing the 0.5" spacer later this year. Might as well do it all while you have the AHC depressurized.

Yeah I agree. I purchased the brand new takeoffs for $190.
Just the right rear spring would be like $180 alone so I figure even if I can only use the rear springs from the 2021 takeoff’s, it was worth it.
If I’m lucky, the front springs will be slightly thicker than what I have and thus be “uprated”/enhanced for my bull bar, winch, etc.
Regardless, I’ll be measuring all the springs, old and new, for spring rate as best I can.
If you can, measure the spring rates, that would be useful info for us all to have.

The springs I ordered haven’t arrived so I haven’t measured them…but most of the numbers related to the lx570 between 2015 and 2016 seem to be the same…except for the wheel weights.
my 2011 was sprung for 79 lbs of wheel/tire (vs 73-74 for a land cruiser and 69 for the heritage edition with its bbs forged wheels).
The 2016 Lexus LX570 has a wheel and tire package of 21” wheels (45 lbs) with 275 50 r21 tires for a total weight of 86 lbs…around 10% increase in weight over the wheel and tire package previous to it.
Currently I’m thinking they upped the front coils rating to deal with those extra heavy wheels/tires.
Does this make sense? That if one were to increase unsprung weight by 10%, it would be expected that engineers would have to increase the spring rate to compensate?
Thus using these higher sprung springs plus, perhaps, some very light rims and tires, would result in a, from a felt ride standpoint, moderate increase in spring rate?
