Im going to be putting 2 add a leafs on the back of my truck. 97 1/2 ton dodge. And a set of 3/4 ton springs up front. It already has a leveling kit up front so i was wondering if i would still be able to use that with the new springs? And the leafs say that they will give you 1.5-2.5 inches of lift. Do you know if that is per spring? And has anybody used these? http://www.4wheelparts.com/Lift-Kits-Suspensions-and-Shocks/Rear-Add-A-Leaf-Kit.aspx?t_c=1&t_s=399&t_pt=5488&t_pl=1853&t_pn=EX P13120

 

If you have the spacer leveling kit up front then yes you can use the 3/4 ton springs with the spacers.
Are you saying you want to add 2 add a leafs to each side ?
If so, probably not a good idea, will most likely ride very rough.
also going that high you are going to need to change other things as well
like an adjustable trac-bar and maybe pitman arm and control arms

 

Yep, that's too much lift for stock componets on the front. You'll need a trac bar drop bracket, longer control arms, a drop pitman arm and sway bar drop brackets. For the back I've never ran across 2 aal's stacked together but I don't think it'd work. They basically just re-arch the springs and anything over 4" or so and the springs get too short to bolt back up.

 

So id be better off getting a single set of 3 inch lift springs for the back. I was going to do the add a leaf because i need it stiffer in the back because i haul a lot if firewood and it doesnt handle it too well now

 

New lift Springs would be best, new springs will also be a bit stiffer than stock, for the wood hauling you could add air bags or overloads.
Like 97tn4x4 said, if you try to arch your factory springs to much they will come up short and you have issues

 

You can use the 3" add aal with out any worries about spring length, they work fine, the ride is a little stiffer but not that bad. 3" is the max lift for the front of these trucks before you need to start replacing other parts.

 

So when they say 1 1/2 inch to 2 inch with add a leaf what does it come out to?

 

Depends on the condition of your stock springs, how much Sag they have.

 

So what all would i need for the front end if i put the 3/4 ton springs and the leveling kit

 

Adjustable trac-bar, longer shocks, longer control arms, maybe drop pitman arm and possibly longer brake hoses.
