I've read alot of posts here and from I gather this is what I need.
1) 5100's for the front set at upper position
2) diff kit
3) 5100's for the rear
Is this correct and will I need anything else, like blocks or shackles for the rear, carrier bearing spacer. I have 285 55 20's on it that are stock. looking to level the truck out.

Thanks for your help.
