Rough ride with Timbrens and Rancho 9000xls
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 stabili...

Ok several replies from folks who don't understand Timbrens or what you have going on.
First, you were looking for sway control, not more load carrying ability.
Timbrens won't help sway(not really sway, but body roll) other than adding more spring rate to the back end making it stiffer. And that's what they did for you.
Forget about the shocks. Loaded with the camper, they don't affect how stiff the truck rides. They don't carry load.
How much did the truck sag before the Timbrens and how much of a gap did you set between the Timbrens and the bump stops? This is where you need to look.
I.e. If the truck dropped 3" before installing and you have 3/4" gap empty, then you're sitting hard down on rubber blocks that make it ride rough. Period.
If you can get some more gap in the Timbrens, take out spacers and washers so the gap is a little less, the same or a little more than the amount of sag, loaded w/o Timbrens, then they will engage later in the spring travel, or only when you start rolling to one side.
The bigger the gap, the less load they take and it sounds like you're sitting down hard on them.
I did this on my last company F150 because it was always loaded and sometimes woefully overloaded. The Timbrens kept me from going down the road doing the Cali lean when overloaded at the expense of riding like a wagon the rest of the time. It's what they do.
