well, most nice leafs will have that built in. it is necessary-because you have to keep the pinion at the right angle to the transfer case. usually about 1-2 degrees under inline with the driveshaft. with all this said...you might have to install the leafs first then,check how much of a degree shime you will need. I didnt have to run any with my BCBronco 11 leafs,HTH

The driveshaft and the pinion shaft should be in a straigh line. If not the u-joint wil accelerate in part of its rotation and decel on another part. It will wear the joint out doing this. Closer to straight is better. Actually straight is best. Use a tubing bender mag base angle finder. Put it on the top of your drive shaft and then on top of the pinion guard. The two should have the same deflection off "0" or be at the same angle from 90 degrees.

I bought a 4" rear lift from JBG (either 5 or 6 pack) and I asked them if I needed shims and they said they do not run shims on their lifts of that size. I still think I need shims.

I hadn't needed to run shims on any of the 10 or 11 pack springs that I've installed. Can you post pics of what it looks like?
