stock rear height measurement

[RCsGX]

For those that have not lifted your GX can you please post up your rear measurements from the center of the hub to the bottom of the fender flare. All I've found are measurements from the ground to the bottom of the fender flare and since we all have different diameter tires and tread depths it's not really accurate.

Thanks in advance!

My GX seems to "air out" a bit after you shut it off, so you should specify if you're looking for the engine off, resting height, or the engine running, air'd up "normal" height. I don't have a tape measure here, but I'll try and grab you some numbers in the next few days.

Good catch. GX off with nobody inside.

I'd appreciate it, thanks!

That's very helpful, thank you! Do you have any bottoming out when going over speed bumps or deep dips in the road?






Here's my measurements, no 3rd row seats, off, nobody inside:
High 22 1/8"
Normal 20 3/4"
Low 19 7/8"


Around town and on the beltway my GX handles bumps great but I'm bottoming out when going over speed bumps and when going over a deep dip in a local road. I thought it was my rear shocks so I replaced them yesterday with 5100s and while it's a great overall improvement over the stock shocks I still bottom out in those two instances. If I have time to put the GX in the high position it's fine but if not this happens....

I know I can adjust the rear ride height sensors but I don't get how in the normal position I'm 1/8" higher than you but in the lower and higher positions I'm up to a 1/4" lower than you? I would think I would be the same if not a little higher in both? What component would cause a difference like that.

I just looked and I do have some wear from bump stop, although I never have felt a bottom out. the difference in height may be due to age of airbags. Again I have never noticed bottoming out, fast or slow, speed bumps or potholes. I have had the GX only 6 months and the previous may be the one who left the marks. The airbags look fairly new, although there is no documentation for that and ALL service was done at dealership. Put some new lift springs on it and be done.

I'm planning on putting 5100s w/ OME springs up front soon. When I do that I'll adjust the ride height sensors to lift the rear and that will solve the bottoming out problem. I was hoping that replacing the rear shocks would've fixed the bottoming out.
