IMPOSSIBLE to LIFT LX570 or Remove AHC?? (6 Viewers)

[TeCKis300]

Unlike most cars where the metal rocker is steel, and a part of the body structure... The metal rocker on the 200-series is underneath a plastic rocker beauty panel.

The LC rocker is a 2-piece rocker + step. The LX has an integrated rocker with step. In order to use the aftermarket LC sliders on the LX, you'd want to replace the rocker trim with the LC piece.

Otherwise it looks like this:

I think the body shop estimate was .75 hours to replace each rocker panel and the LC panels were surprisingly affordable. They would probably have to be painted too. If the Canuck buck ever regains First World exchange rate I’ll be in touch with Slee for my sliders.

LC200 sliders will not work on the LX570. The plumbing for the AHC system runs along the frame rail where LC sliders would normally attach to. I heard LC200 rear bumpers won't fit directly to an LX either because of other components on the LX being in the way. I was waiting a long time for armor to come on the market for my 570 but I finally just bought an 80 series to wheel. The 570 is relegated to easier trips.

If you can find anyone who happily removed AHC from a 570, it will be big news here.

Guys its FAR from impossible !, almost all lx570 especially 2016+ have the AHC system removed in my country, only downside is dashboard lights. Dont cut the stock wires tho! Ive done it myself with a help of a mechanic and some energy drinks.

MOOORE..

As far as I can tell the issue is it would be very expensive and difficult to retrofit the KDSS system to a LX570. And without KDSS, it isn’t going to flex very well.

Otherwise shocks AND struts seem to physically bolt up and “work”

I was looking at the LX570 rocker/side steps unit today. At least some of the vertical/supporting portion is sheet metal. The profile to mold into the step is thicker and could be plastic I think. I'm not talking about the cheesy brackets that attach underneath. I'm talking about the part that would stay if you ground the step horizontal off.

Not necessarily true, while the KDSS offers some really neat handling features, it doesn't add any total flex or wheel travel.

Our LX570 (Canguro's Monica) has been converted to traditional fixed rate sway bars. The issue isn't so much the mechanical ability to convert, we all agree that is easily done. It's the fact that those flashing lights and errors on the dash are enough to lead most away from this as an option at current.

I understand that it is a different chassis but I recall reading that KDSS makes a huge difference in RTI score on GXs.. 519 with vs 428 without.

And yeah, I wasn't even thinking about dash lights. I do believe this would be an easy fix for someone with the right skill set. There is a guy in the 80-series section putting a mercedes diesel engine into his 80... and supposedly has an ex-soviet fighter pilot computer engineer helping him remove the immobilizer and other modules from the ECM. Other guys are programming GM body control modules to flash instrument cluster backlights as shift lights..

One guy doing the proper homework could easily fix this problem, IMO.

I'd love to see a side by side on a 200/570. Up travel is controlled by bumpstops, down travel by shock length. Certainly swaybars impact ride and flex but that us a rate and length scenario and a 570 with traditional suspension can cycle full range.

Companies are working on a module that will trick the ECU into thinking the AHC is there, but we've not seeipn an available unit you.

Can you elaborate on "dashboard lights"? Which ones?

 

[TonyP]

All things being (equal besides) KDSS, there's no chance a KDSS vs non-KDSS will flex more.
Arms/links can only articulate so much.

Now for how nearly all of us use our rigs (90%+ on-road use) where the the KDSS shines on the road.

@TonyP -I don't think that is an accurate statement -all the KDSS materials I have gone through expressly states that KDSS increases flex -it acts to push the wheel down to retain contact with the ground (and effectively stops working as a stabilizer).

This video might help the KDSS wheel travel debate
Video is on a Prado not a 200 though
Not sure how good the comparison is since it compares a 470 (120) to a 460 (150), neither of which are a 200

I'm saying the arms can only flex so much.
KDSS itself doesn't increase that mechanical "limitation".
That said, there's more than swaybars that come into play to having a twisty suspension.

 

[Mogwai]

Me so confused. I thought KDSS = more flex. If you had a fixed sway bar, you'd have X travel. If you relieve a link on one end and allow the bar to flex more, you should have X + whatever you just gained by allowing the truck to act like the sway bar is not there.

OR, KDSS allows use of a much stiffer bar for better on-road manners while allowing the same flex off road as a rig with a softer bar.

Hypothetically anyway.

Personally I suspect the truth is somewhere in the middle.. marginally better on-road performance AND marginally better flex.

To @TonyP point, Yes, bump stops and shock length ultimately limit travel, but whether one side is fully stuffed while the other is fully dropped out in a given situation can be influenced by the sway bars. See the front left wheel well gap on the preview of the Prado video above.

Darren @AutoCraft Aus is working on a STFU box for the LX570. When he has it figured out, I plan on SLINKIFYING a US spec LX570
