80 series guy needs advice on 200 series vs. LX 570

[TeCKis300]

I wouldn't want a truck that auto lowers at 29mph (I wouldn't be able to test the LX as you suggest, in the same way I use my LC since desert and faster speeds are in play)

This is shortsighted. Yes, it lowers to "normal" height, but normal is where-ever you'd like to set it. You can do an AHC sensor lift to set N at 1.25" higher than stock with 10 minutes worth effort, or higher by making brackets. Which means that AHC "High" now is 4"+!!! higher than stock for obstacle clearing. With N coming back down to whatever lift you had set.

Damn...another LC vs LX thread but executed so incredibly well! I have really enjoyed reading the knowledgeable responses, especially the recent ones added by @Tremek and @TeCKis300 .


In closing: no kidding, three days ago I came up behind a guy in what seemed to be a slammed Mercedes SUV ML-something or other sitting way low on the suspension and jumping and bobbing with every bump in the road at 60 mph. My first thought was "Why the heck would someone slam THAT thing?" As I passed him I looked inside and saw his entire family bouncing around and hating it and realized the guy's active suspension had failed and the poor guy was stuck in "Low". They looked absolutely miserable and embarrassed...

Was me about 2 weeks ago......resurrecting this post to share an update on the AHC system. Had an AHC fail, stuck in low (would not raise up after pit stop on a long ski trip). Still dealing with Lexus/Toyota, but it appears one of the AHC lines corroded and AHC fluid leaked out. LX is a '10 w barely 140k miles. I'm sorry, but 8 years is all I'm expected to "get" out of a simple "pipe".

Incidents happen and mechanical systems can fail. No system is forever bulletproof, yet AHC has proven it's durability with relatively few failures reported in the 200-series.

In fairness...

You may want to know that many aftermarket coilovers require rebuilding every 30-40k miles. Even the most bulletproof OEM/OME/Bilstein shocks are typically done at 100k. AHC has the advantage of being maintainable with the ability to be refreshed and flushed onboard.

Pick your poison.

Agree, but in my instance, we're talking about the "pipe" that transfers the AHC fluid - not the pump, the accumulators, or sensors - the simple line. I could understand anything else in the system, but the "pipe" corroding until the ACH fluid leaked out? That's crazy.

Quick question, can anyone confirm if this schematic is the 470 or 570? If the 470, does anyone have access (and could share) to a similar drawing for the 570?

Many thanks

Looks like 470. The fluid reservoir is in back on the 570.

It's most definitely the LX570 AHC block diagram.

The LX570 system is more advanced and adds several features, including secondary spring rate on the front axle which uses the #2 gas chambers. That's the dead giveaway that this is the 200-series system as it has 6 "globes" / chambers as apposed to 4 on the 100-series system.

@tbisaacs , this is a system block diagram and doesn't suggest location of components on the vehicle. Only how they are interconnected.

THIS is outstanding, thanks so much!

Thank you, really appreciate the confirmation.

This "place" never ceases to amaze me
