Fluid changes must be so easy. I might need to do this for my back...Portals for "medical reasons"...I'll see how my insurance company likes that invoice

Ok AHC experts. Did a shake down run of the portals and 40s and swayed like a boat in a stormy sea, and bottomed out just going up steep inclines. I’ve added westcott preload collar lift already for support, and LX 450 rear springs (higher spring rate).
Have I just exceeded the capacity of AHC? What say you??

Globes are new and flush was recent btw.

My first vote is for a stiffer rear swaybar and possibly a custom front swaybar next. But I’d like to hear from others. @PADDO have any opinions?

I don’t think it’s exceeding capacity, more like physics. The wheels are in a very different place, creating a much bigger lever.

preload / rear springs and maybe thicker rear sway bar would be my recipe to start.

The wheels are in a very different place, creating a much bigger lever.

This is my guess as well, mostly with the front suspension. The distance between contact patch and original hub centerline suddenly got 25% larger, even coming from your existing tire/wheel setup.

 

[XFACTR]

Yes I think it’s the leverage. But it’s not just with the front. I’m bottoming out in the rear just going up an incline.

That has me wondering if there's anti-squat built into our rear suspension that is going haywire due to the new hub centerline.

Does it do it under throttle or just with an incline?

Just with incline

Can you explain what you mean by bottoming out? Like hitting rear bump stops hard? Are your bumps still stock?

Yes. Perry parts

Motion ratio especially front axle. Meaning the tires are much much further outboard. I'd go so far as to suggest using OEM 200-series LC front springs.

This can be calculated too. How much further out are the hub faces?

Rear axle doesn't work the same so your uprated springs are probably sufficient there. Though a heavier rear sway may be useful.

From my understanding you’ll need to convert to 6 lug.

This ended up being caused by a bad tone ring. Threw the entire AHC out of whack because it couldn’t determine wheel speed, so it went into limp mode.. Easy fix, but I’m deleting AHC anyway. It’s time for an offroad specific suspension.

Glad you figured it out. And kudos for continuing to push the platform!

Glad to see they’re making progress. I’ve been periodically bugging them about it lol.

Not sure how different the new LX700h AHC system is compared to the LX570, but Dissent seems to be running their portals on the stock AHC without any issues.

I’ve been bugging them too. Quinn told me this quarter for the 200 Series portal set.
