...aftermarket First Gen cummins springs
...there really isn't such a thing as "Cummins" leaf spring, and really there isn't much of a difference between 1/2, 3/4, and 1-ton leafs. And best I can tell...in all my years of messin' with leafs...the only
difference is the number of leafs per pack, and it seems whatever you order all seems to have the same number of leafs....unless they're custom made of course. In other words, you likely won't find a leaf spring specifically for a 1-ton Cummins front end - you'll just find Dodge Ram springs, period. And I'm likely not even going to use a "Dodge" springs again as they're all too short - i want the longer ones for both the ride and the flex, and that means going Chevy....and they're cheaper - bonus
What I might suggest is grab hold of a set of the 52" ProComp rear Chevy leafs, at the lift you want, do the 1-time fabrication/modification to the frame mounts, remove the bottom leaf (plus the 20-ton overload, as so many seem to come with
), bolt it up and run it. I bet it rides awesome.
I'm fully planning to eliminate at least the lower leaf, maybe the two bottom leafs from my 56" Chevy 4"-lift procomp pack for my front leaf setup. I proved that the just 3 of the original 5 leafs in the 13511 spring pack will suspend Nacho's heavy front end, just 3. But, while removing leafs will gain a better ride it will also lend to spring wrap. To counter that I'm planning a simple wishbone setup, front and rear, to swing with the fixed (non-shackle) end of the leaf springs.
If you get the 4" lift spring, and remove a leaf, and set a 6bt on top of them, you'll already be at a 2" lift, which will nicely put you 'in' the spring
. Have you seen the threads about having the truck riding 'in' the spring verse riding 'on' the spring?
The only thing that has me at a stand still on this project is the transmission. I want to run a 5spd either a Getrag but perfer a Nv4500. But i have yet to get one yet for the right price. I have a2wd getrag but the shift plates and shifter are wasted. I guess as a last draw i could go with a auto, but really don't want to go that route
yahh, trannies are often the single most spendy...and critical...part of a big project. If you really want a 4500 I say just have faith and patience and keep scrounging and you'll eventually score one.
