    Hi there, I have the same truck as you and was wondering the same thing. I do a lot of towing with my truck and the rear is starting to sag. Let me know what you find out!!

    just make sure the length is the same. it may cause your truck to site a little higher in the rear if the spring pack has more springs. I am not sure for newer truck but on older trucks when you purchase a new lift the springs are the same with the changes coming in the size of the ubolts do the the thickness of the axle tubes. Make sure to measure the from eye to eye!

    I would just get a spring helper kit (add a spring)..
    And its not just your springs, your axles wont take the extra load like a 3/4 ton or 1 ton..
    I hauled many loads of firewood back in Michigan,Axles do break.. My .02 ....

    Yes, you can, my cousin has a 2001 with 3/4 ton leaf springs in it. To be sure, measure how wide your leafs are, and how wide 3/4 tons are, they should be the same, the only difference is the thickness of the metal used for the leafs, and how many leafs are used.

    did your cousin use the same exact truck, like RCSB, RCLB, ECSB, ECLb etc.. same year, 4x4/2x4. also what did this do to the ride height and ride quality of the truck? what about the front did he change the torsion bars, coils, CA's etc

    Measure the width on yours & a 2500, the length from mounting points (make sure you measure the same, if yours is sitting with nothing it make sure the other is to!), you can get a longer shackle if you want it to sit lower in the rear or get a leveling kit for the front.
    I did it on a Ford F150 & had no problems, just measured twice before I started.
