LX570 AHC height modifications (lift it!) (1 Viewer)

[Trail Novice]

of all the reading I've done on various sites, it seems that 33's work fine, 34's need minor trimming. I don't think I've seen anyone try 35's.
For one of my vehicles an installer mentioned doing a cardboard mockup. That should probably go over the top portion of the existing tire so the load on the springs is correct. just a thought

A few of us are running 275/65r20s, which are basically 34x11. These require removal of the front rear mudflap and some modification of the front forward fender well plastic. I'm also running 3/4 spacers from bora but I think some folks are running this size without spacers. I initially attempted to fit 35x12.5x20s in there but the rubbing was pretty extreme.

It may be possible to get 35x11.5s in there. 35x11.5x20 Nitto Terra Grapplers are only about 1/2 inch larger width and approximately 1/2 larger diameter than what I'm currently running, according to Nitto's website. This size would most likely require running spacers.

I have read through the entire thread. I am starting to get the 200 series itch. But in my head I have already told myself I won't do the 570 because of potential suspension issues. This is come from owning my 470 and having the AHC rear sensor fail I had good pressures and good AHC health. The failure happened when adjusting the sensors for the first time in my driveway. I loved how it rode but this made me paranoid enough to rip out the suspension and replace with OME. Has there been any issues with failures with this system any know issues. Cost of replacing globes and sensors?

It costs the same as the 470 suspension to replace, around 350 a corner.

Seriously, don't let the perceived unreliability thoughts keep you away from AHC. It's a phenomenal system. It's proven to be competent and robost, even more so than in the 100-series. You'll be be missing out on one of the greatest features available to the 200-series, or any "all terrain" vehicle available today, because it is an active system that can adapt to load and conditions. You can't get this duality without it being intelligent, to actively change spring rates and damping to suit.

The only other place you might find an active suspension like this is the military Oshkosh JLTV:

$1400 isn’t serious money in suspension. Even if it was every 8 years that would be nothing.
My minivan has a conventional suspension, the front all in one is $1400 each corner. The only drawback to ahc is they stuck the accumulators where sliders need to go.

the top of the range nissan patrol has a similar set up but is not hieght adjustable and being full indepndant there is now a company over here making lower control arms that lift the whole vehicle 2 inches so not effecting shock travel. if i was to look at another full size tourer id be considering a patrol as an option

In the US, Hydraulic Body Motion Control (HBMC) is offered on the Infiniti QX80. Not available on the Nissan Armada. It's a completely passive hydraulically linked system meant to replace sway bars. Very similar to the KDSS system in the LC.

Doesn't hold a candle to what AHC does.

I'm not sure how many other 200 LC owners share this opinion, but I'd personally have no concerns with the LX suspension onroad or offroad. I'd probably keep my build a bit lighter but that wouldn't be a bad thing

I completely agree and I have driven the LC and LX back to back off road. My decade old LX with 165k miles on the original suspension is amazing on and off road, and in many ways I prefer it to the BP51s on the Land Cruiser. I would not however load up the LX with thousands of pounds of weight and expect the same performance. A very light build is all I’d feel comfortable with long term on the AHC, and I think in that use case is a better value than the LC. I also find the two to drive very differently on road, and in virtually every way the LX wins there too.

im waiting for someone with the money to have extended ahc sho ks made and to use a slightly longer and slightly stiffer coil to taje a heavier build.

The first picture is the front sensor stock
The second pic is how i moved it.

It was rather simple. I didn't even take the wheels off. I Set the system to High to give myself room.
I pressed the Off button on the AHC system so it didn't move and then turned the car off. The front sensors you slide all the way DOWN (see pics for reference). I didn't get a pic of the rear, but you do the OPPOSITE. You slide them all the way UP. the end.

Interesting! So no messing around with techstream. Just adjust the sensors and you are good to go!
I know its a very old post , but did you face any problems. Did you get spacers? Or crank torsion bars?

No torsion bars on the 200 mate!

Wow... So this means no cranking, no techstream, just 10 minutes of adjustment. Now I know what the gx 470 replacement is going to be. I got 2" ome lift which gives me offroad prowess, but the ride quality is now 4runner like. When I upgrade my rig I was thinking LC or lx... Was gravitating towards LC, but then stumbled upon rave reviews of the "newer" system.

1.25" lift and then another 2" with H when rock crawling. What more do we need!
And I see 33.8" tires fitted on this very thread. Thats the max I will go. Infact, I currently run 32" only.

Last but not the least, thanks to cult status, I can get a newer LX than the LC for the same price with better features.

 

[stellz996]

I believe to do it pdoperly the shock pressures still need to adjusted on the techstream fo suit the new hieght,

 

[SWUtah]

So you guys think 1.25 more inches makes a difference? so the engineers and designers at Toyota and Lexus didn’t design the vehicle correctly and we actually need 1.25 inches more ground clearance.

In terms of engineering, there is no "correct" setting. Everything is a compromise. Lower ride height has it's benefits as far as on road handling etc. If you find that your usage is more geared towards being off road, then raising the vehicle is a good compromise.

That’s why you can raise it to high when you’re off road the higher you are the less stability you have on road

 

[stellz996]

I personally think the whole car shoukd sit higher from factory both in lx and lc. Over here in aus our v8 70 series cruosers still come standard at the hieght a 200 would sit with 3 inch lift

Bigger tires sometimes warrant a lift. If you are using your vehicle a lot off road, you will want additional clearance and take the hit in handling/ride quality. That is why you see Air bag conversions in GX world being so common.

Its brilliant LX gives you this without much effort.
