Rear Spring Shape
I am trying to figure out if my rear leaf springs are bent. I have an 2005, F250, CC, 4x4, V10 King Ranch with the stabalizer package. This is a 9600# GVWR. When I look at the rear spring they dont have a continuous radius from shackel to shackel, rather there appears to be a flat section over the axle mounts and then bend down slightly at the U bolts before curving back up to the shackles. I stopped at a local spring shop for advice and was told the springs look normal.
Is this correct?
BTW- I have already installed a set of Timbren SES rubber leveler springs and they have the normal spacing between jounce stop and spring on both sides.

I've got some 05/06/07 250 & 350's at work. If I get a chance tomorrow and one of them is at the shop in daylight I'll snap a photo and post it. Maybe someone else can post a pic if they have one closer by.

Hey Chris thanks for the picture. Those look similar to mine from this angle but it is hard to tell. If your received my pictures can you tell me how they compare. Also, in your picture there is an extra leaf over the top of the spring pack, is this OEM or did you add it?

I never did receive any pictures from you, but have been having some email issues lately. If you send them again I'll post them.
The extra leaf is the factory overload spring. It's designed to provide extra support once the truck sags a certain amount. You can these overload or helper springs as an aftermarket item.

Here are the photos from Hobie16 the original poster. These are pictures of his springs. I think his springs look fine. I believe this is just how the newer trucks are attempting to get a smoother ride.
What are others thoughts.

As for the OP, i dunno, im not overly knowledgable when it comes to springs but they dont look right to me. And there is no helper spring on top either? did you own the truck since new?

my 01 springs look exactly the same,the previous owner at one time had a fith wheel hitch in it,and I see that yours has a fith wheel hitch also or had at one time,so either both of our springs are shot or more then likely that is how they are.

I have looked very closely at the individual springs and can not find any cracks or other indications of broken leafs, just the odd curve pattern. You are right about the 5th wheel. I tow a 32 foot Lakota and the pin weight is 2100#. My firsts trip out, about 400 miles, I was unhappy with the amount of sag so I installed a set of Timbren SES rubber springs [ http://www.anythingtruck.com/susp_timbren.html ] now the truck only drops about an inch and a half more than the front when I put the fiver on and the springs pack look no different than when unloaded.
