Good info. I think I may try that.
FYI- I installed the Rough Country 4-6 inch lift (front lift depends on torsion key adjustment but nets approx. 4 inches with just brackets alone) and it fit really well. I upgraded from torsion key lift and it rides much, much better! Price was $899 for front and rear complete kit (black friday special/ rear is blocks and not AAL or full leaf packs) but has gone up to $1099 (reg 999). If you want to keep IFS and not SAS, there are not too many options anymore and I was very impressed with the fit on a 25 year old truck. Only thing I want to add are kicker bars to support diff cradle and real lift tb relocators to get rid of the drop brackets. Other than that, it is one of the only options left for the k2500/ k3500. If you would like more reference pics, I have added a bunch in the RC 4-6 inch stickey thread.
