The spindle bearings/journals are larger on the heavy suspension (D250 cummins and D350; aka '4000#' suspension, but may be 3800ish in the actual truck.)
You also need to see where the caliper ends up. D150 (5-lug) uses a small diameter rotor. I don't know if the difference is accounted for in the spindle, or in the caliper bracket.
FWIW, I'm content with stock height, and adding extra tire on the rear only.
I found these, and I'm thinking of giving them a shot with the lowering springs. Still a little unsure of them.
