I got a set I have to put on next week. I used bags before. I thought I'd give Timbrens a try. Easy to put on. I have a Lance 820 that weighs 4k ready to go. We'll see.

to those who are already using these - how are they different from the stock (yellow) bump stops? They look very similar... the online instructions say to remove the bump stops and install these in their place. I'm assuming they are bigger or somehow mounted lower... otherwise, how do they assist in suspension other than preventing bottom-outs?
They are longer than the factory bump stops and sit about an inch off the axle tube. When the suspension is loaded they make contact and compress under load to give progressive assistance
your truck will ride on these timbren bump stops so you have less suspension, I think Helwig helper spring kits are the way to go then you still have suspension movement. When the truck is empty it will ride like normal.
On my 2008 F250 6.4, I had the Timbren. I had a tool box plus a 5th wheel hitch. The Timbren rubber springs that Timbren specified were too tall (since I already had the bed down an inch or two with the weight in the bed.) It provided no gap between the rubber and the jounce stop. They sent me a shorter Timbren spring that gave me an inch clearance. It worked great for three years but seemed to just wear out and not provide the stiffness when loaded. It did work for keeping the bed level.
This is a photo of my 2008 6.4 with Timbren SES. It should work basically the same on the 6.7. (Don't have overload springs)
I have had the timbrens on for a week or so now. the problem IMO is the factory right height or the f250 should be about 2" higher in the rear, but ford probably sees that tons of people wanna put leveling lifts on these trucks and are responding to that by lowering the rear. to me I HATE rear end sag it makes the truck look terrible. I can't tell you how many lifted trucks I see that it looks like apparently they also forgot to lift the back end, the proper right height is a slight rake, with the rear being higher.
so with that said these trucks already sit almost level as it is ANY load is going to sag them a bit so you don't have a whole lot to work with that is if you want to keep it level or slightly raked. the timbrens I bought were listed for the 2010 f250's I found that the supplied rubber thing was too long, and touched the stopper with no load on the truck, I called timbren and they sent out a 1" shorter rubber thingy, this was the right fit, with my trailer I was getting about 3.5" of sag over factory height, with the timbrens installed I am seeing about half that, but the truck still looks a bit lower in the back than I would like. but this is no fault of the timbren product. if I put a 2" lifting block in the back and got a 2" taller timbren I would probably be about ideal.
as far as the ride, the timbren defiantly makes it more harsh but for some reason it doesn't seem as bad as when I first put them on, maybe they broke in. I also suspect these will work even better with extremely heavy loads, I think the harshness will be reduced, I really should have gotten the f350 instead, but the timbrens work and for a guy that only tows load occasionally I think they would really be ideal, but I tow loads more often than not.
so what I'm hearing is that maybe I should get airbags. At least those will give me a *variable* amount of assistance. it sounds like the timbrens are too specific and aren't going to be right for everyone's application
my dealer gave me a money back guaranty if I didn't like them. Not sure if applies to all timbrens or if it was just my dealer but worth looking into at half the price of air bags
I'm installing Firestone Ride Rite #2535 air bags (a no-drill kit) on my 2011 F250 CC 4x4 this weekend. I have a Pullrite 16k SuperGlide 5'er hitch in the bed. Under the truck bed I used the Pullrite SuperRail mounting kit. During my pre-install review under the truck I found the drivers side hitch bracket needs to be removed in order to make the upper air bag bracket install. The Pullrite mounting bracket covers the 3/8 inch bolt the DEF tank bracket uses to attach to the truck frame. The Firestone kit requires removal of the stock 3/8 inch DEF bolt and replaced with a new bolt from the Firestone kit. Reason: the upper air bag bracket is also attached at the exact same point where the DEF bracket is attached. Anyway, just trying to give someone else a heads up should this same combination of component be used.

Reason: better info...
In my own opinion I wouldn't care much for using a bump stop to help carry the load. I put a set of Ride Rites on my Bro-in-laws truck with the in cab controls 6 years ago and he loves them.
