Okay I know what overload springs are, but I'm not sure if my truck has them? 2007 f250 4x4 crew cab short bed lariat 6.0L. Ha I bought the truck used and not sure if I have the camper package/snow plow package on the truck. I've had friends tell me that I do and friends tell me that I don't.... I have 5 rear leaf springs on each side, (of course). I got a bud with a 08 350 and I can clearly tell that he has the springs, (has 6) but I've heard the 07 and 08 overload springs are different on those two years. Anyone have pictures of rear springs with and without the camper/snow plow package for an 07 f250 superduty? That's all I need to figure this out. Again 5 rear springs. Thanks!!!!

 

There is the main leaf spring pack, then above, there will be one extra separate from the main pack.

 

I also bought my truck used. I made a call to Ford main phone number and asked who to speak to regarding getting a copy of my window sticker. They transfered me to someone who took my info and VIN and 2 weeks later I had a letter in the mail, basically calling out the items on the window sticker.

For the springs ... in the pic below the top spring pack is the new set I bought, the bottom set is the old one off my truck. That lone spring sitting out on top is the overload spring. I then had the spring shop move the overload spring from my old set to the new set. Having them do it was quick, easy and $13 total for both sides.
My truck is a 2003 6.0L 4x4 CC SB with tow package. Hope that helps.

 

08+ trucks have a whole different set of leafs from the 05-07 trucks

my F-250 has the same setup as the leafs in the bottom (shown above). I thought I had an AAL or something. It just looks strange doesn't it?

 

My pack is the same as the pack in the top of the picture. Guess don't have the overload springs. Didn't think I did, but that answered my question. Thanks for the pic!
