I have a 2011 GMC Sierra All-Terrain and I plan on putting a 2.5 level with a 1.5 or 2 inch block in the rear and I was wondering if I will need new shocks or if the rancho shocks on it from factory will work? and what size is the factory rear block?

No your original equipment shocks will not work because your new suspension lift will stroke them longer (such as going over railroad tracks) and the shocks will "top out". No idea on the original factory rear block.
