Hey guys I bought some degree shims for the rear axel, I'm curious how you guys go about installing those? It looks like I might need to remove the leaf springs and remove the factory pin and install the new longer pin with the shim bolted to it then re-install the leaf springs. Is this the correct way to do it?

Yep just like you said. Drop the axle from the leaf pack and use a c clamp to hold them together

Ok thanks...

Now a dumb questions for ya, high side of shim in back correct?

Depends on which way you need to adjust you're pinion.
Did you figure that before getting shims?

4 degree shim, I lifted the truck so it needs to rotate up lol

Yep, thick side out back.
