I do plan on replacing all leaf springs and am hoping for a 4 inch lift while using the Dodge front and rear differentials (reportedly with 3.08 gears). I need to gain knowledge of a spring pack that will hold up the heavy weight of the Cummins while getting the 4 inch lift. Do you know of a leaf pack package that I could purchase to accomplish this?

Any help is accepted and appreciated. The easier (through other’s experience) the better! Thanks!

I have rough country 4" lift springs for a square body on my truck. I converted my truck to 4x4 and used the stock front hangers. I had to cut the frame for the shackle hanger so that allowed me to use the square body longer spring. I'm sure the 4" 67-72 springs will hold the weight as well. They will just ride more rough due to the shorter length.

If you have 3.08 gears you have the D61 and D71 axles. There used to be no aftermarket gears for those axles. There are some now.

It looks like you have a good collection of trucks there. Are you using the old powertrain in another project?
