My truck had the HD rear 4 leaf springs. I think the standard leaf setup is 3? Not sure if I would want to pull 33% of the leaves on the back.

I removed the overload on mine because it was hitting the CalTrac bars after the flip. Removing the overload gets you 1/2”-3/4” lower if you keep the axle spring over. Combine that with the shackles in their lowest hole and you are getting closet to 4” drop.
