Lift kit and AHC

[Viking77]

Hello out there

I bought my LC 200 V8 turbo diesel 286 hp from 2010 6 month ago, now i bought a constant load lift kit from ironman, as i had on my LC100, very satisfied with it, but my old LC100 did not have this AHC on it as my "new" LC200 has, so my question is.... What did you guys do with that system, delete it all or what can you do??
And a pic of the 200 from the cold north in Denmark

Regards
Marc

The Ironman kit won’t work without deleting AHC. Why not leave it if functioning?

A couple of people have deleted on the LX. It involves disconnected the suspension control module and relays and then pulling the battery so the ECU forgets that it has AHC.

Don't delete it. It's the best suspension you'll ever have, bar none. Over 4"+ lift, no problem. 1800lbs payload, yup. While always delivering spot on damping and ride.

Work with it to get what you want.

Without much effort and a 10mm wrench, can lift the suspension by adjusting the height sensors at each corner for about 1.25" lift. You can access another .5" or so via the techstream offset utility. You can get more still by modifying the sensor connecting rod or a bracket. Combine that with the on demand 2.4" lift, and 4"+ is possible. Combine that with tall tires, and you could be at 6"+ lifts.

AHC Height Offset Utility How-To

Height Offset can adjust a maximum of .8", so you move the physical sensors first, and then you have .8 to play with. 1mm of movement on the sensor equates to 2mm on the rig. In theory, assuming there’s enough stoke in the shocks, you might be able to add .8” on top of the “sensor lift” method...

In the US, only Lexus models got AHC, so you'll want to search for suspension and fitment info from the LX. Which also means your LC can more easily fit bigger and wider tires as you won't have interference of a KDSS bar.

Many in the forum are running 34 and 35” tires with the stock ahc and sensor lifts as @TeCKis300 described. I am running 35s (measure 34.8” on the rig). One member is on the way to 37” (already test fit) and has also test fit 40” (though that has more clearance issues with fenders).
If you want to delete anyhow, look up turbo8 thread. He’s got the steps in it.
The 200 series ahc is not the same as the 100 series tech. Several more features.
