Backstory: I'm in the home stretch of swapping axles in from a First Gen Cummins truck (Dana 60 / 70 Combo with 3.54 gears).

Thanks for the advice on the Skyjacker 1.5" - 2.5" Softride Leaf Springs for the front. Now that I've got those installed and the front of the truck sitting on it's own weight, I've got the rear sitting on jackstands to level the truck and measure how much lift required to level it off.

It appears I'll need 4.75" of effective rear lift to make it sit level. My goal is to level it WITHOUT sacrificing ride quality.

The truck still has the OE rear springs and blocks between the axle & springs. I'm thinking If I go with the Skyjacker DR40S (4-6" rear lift springs). and perhaps front Hangar's from Jungle over on RCC, I can then fine tune the height with a custom spring shackle and perhaps even get rid of the factory lift block.

Once all that's done, I can get some measurements and figure out if or how much the driveshafts need to be modified to bolt them up.
