Rough ride with Timbrens and Rancho 9000xls

[dakonthemountai]

So I thought it would be a good idea to put Timbrens on my truck. The Lance 1055 camper is tall and a bit top heavy. It didn't ride bad or sway badly, but I thought that this would help for stability. And they do! No sway or roll, however now it seems the truck rides like a washboard over the smallest bumps like it never did before. Is this overkill? Should I readjust the rancho shocks to a lower number? I have them on nine before the Timbrens and did not change the setting. Have any of you experienced this issue? The freeways through Pasadena and Glendale were shear torture for the first time ever! The bouncing and jarring over the smallest bumps in the road has become really annoying. Thanks for any help or insight you can provide.

Good morning all, thanks for the replies. To answer a few questions, yes the proper clearance was achieved netween the bed rails and the Timbrens, yes I have facory overloads and they do/are engaging properly. I didn't put both the Ranchos and the Timbrens on at once. I've been running the Ranchos for a couple years with this Lance amd my last camper. The sway wasn't "bad", but I wanted a little more stability which is why I added the Timbrens. Perhaps the way it was was what I should have been happy with. In any event, this afternoon before the next leg of my trip I'll crawl under and turn down the Ranchos.

Thanks again !

Yes, try turning your ranchos down. That's why they are adjustable! It should help at least some, especially unloaded.

Also, this is a good example of why doing 2 suspension mods at once my not be a good idea. You won't know which one is helping or hurting you.

Comfy ride for me.

You really got to play with the setting. Drive the same route of bumps until you find what works for you.

Keep in touch,

1) Tembrens do not use air...
2) Empty with no load in the bed there should be about 3/4" clearance between the Tembrens and frame rails.... If not, you may have the wrong model Tembren.
3) Does your 3500 have factory overloads?? If so, are they engaging properly when under a load? If not, add stable-loads to engage the overloads.
