leaf springs

i noticed on my truck that i was missing a leaf on one side. can someone tell me how many leafs came in the 350s? and can you buy different leaf packs with different numbers of leafs in them, other than taking them apart and adding more leafs.

Five leaf main springs.

I had a set built with 7 leaf mains, running five leaf overloads on top of that.

Front 2 rear 5.. Snow plow package gives 3 leafs up front and still 5 rear. You should call around to local shops, or hit up a salvage yard.

thanks dave and power stroke for the info, yes im planning to look around at some junk yards and see if i can find a set in good shape. i would realy like to find a pair that has more leafs in it so i dont have to worry about the weight of my fifth wheel camper. the front of that camper is very heavy, i know it used to squat a 2002 f350 pretty good. so i would imagine it would squat mine to. i havent had a chance to really look at the springs yet to see how there put together, but i know on the chevys ive had in the past that we used to build our own set of springs by addind as many leafs as we wanted in them. can you do that with these?

The springs are in packs and the u bolts are specific sizes as are the blocks for a certain amount of lift empty and sag full. You could do airbags... Adjustable, and you don't sacrifice ride empty... For a more level and stable ride loaded, I would fix the missing leaf and then add ride rite bags or equivelant.

Not sure, but I think the newer fords have longer springs that are intended to give a better ride when empty, but also make them more prone to sagging when loaded compared to older trucks. Five healthy springs may be all you really need.

All of the springs I have seen lately have a center bolt that has a big tapered head to center the axle.
Most spring builders cut the center bolt off so short you can not add a leaf.

It has been a couple years since I replaced the back main pack, it was only 300 dollars for both springs with two extra leaves at a local spring shop.

Front springs with two extra leaves each were 600 dollars last year.

Longer leaf springs with similar characteristics in spring metal quality and thickness will under the same load exhibit more 'sag' because more torque is being applied to them. So if the newer F-series have longer leafs, (1999+) then the fact that the newer truck sags may not necessarily mean that your older truck will...
