RAS without XREAS? Help!

[Keros]

Oh, I know. My original XREAS had around 290k km on it before I removed it. It was shot. Speed bumps were eye wateringly painful.

I detailed some of my adventures on here. I think I called the article "My Bilstein Adventures" or something like that.

The wheelers superbumps will give you a cushy soft landing for those times you get a little over exuberant over big bumps.

I can't say enough good things about them because they really made the truck versatile and comfortable at stock ride height. There's been a couple of times I've been hammering down the highway and hit a big bump or a dip big enough to touch the superbumps.

They may have been intended for hitting sweet jumps... and maybe one day. For now though, they're a nice cushion against my crazy right foot.

Thanks Keros and RobD for sharing your experience.
The reason I am looking to swap my Xreas is -
I had to park my 4runner for 3-4 months for this winter, which for this year was extremely long..So, as soon as I started driving it again about couple of weeks ago I felt the ride was harsh. The front seems to work fine but the rear shocks I think were not compressing enough. At slow speed it seems fine but around 55-60 kmph in city I could feel the bumps.
So when I checked the rear suspension it seemed that it has sagged a bit. I seem to remember that it was higher than it is right now. Cause I bought the Daystar leveling kit for the front to level it out, But now it looks that the front spacer will make it nose high.
I took the measurements of my stock ride height from fender to hub is 19 '' front and 20'' rear. It has definitely sagged an inch or so. Can this happen when you park your car for a long time?
Is this my only option - to swap the suspension? Or is there still any other option I can try before swapping the suspension?

From my understanding, assuming everything is working properly, the ride height sensors and air bags should prevent any sag from happening in the back.

You could try adjusting the ride height sensors to get the right height back into spec. Someone linked the how-two from the manual on the first page of this thread.

If your results from the adjustment are hay-wire, chances are your sensors are toast. Which would explain why they've let the truck sag. Or a part is bent or otherwise out of adjustment.

In any case, the RAS is intended to prevent saggy-butt 4Runner. And if it's working normally it will. I've pulled some seriously heavy trailers when my truck was young and the bags didn't let the butt sag a micron. But all good things come to an end...

Ride height and the XREAS are independent from each other, of course.

thank you for posting your conversion results

Did you keep the 5160's in the rear or use the 4600?

I'm in the same situation with XREAS failure at 146,000 miles and I'm doing 6112's and springs in the front but still figuring out the back.

My other option is 5160's and springs with Air Lift 1000 in the rear.

I did a cycle of deflating and inflating the airbags, seems to be working fine. I will check on how to adjust the ride height sensors and see if it makes any difference.

I used Bilstein 5160's and MOOG springs out back at stock ride height.
