What is the height of a rear factory block?

Will 275/60r20's fit with a RC 2" leveling kit with no trimming?

I don't know about a 2.5" block but there are 3". You could also put on an add a leaf instead of a bigger block and get ~1.5" in the rear.

Probably a stupid question. But, if I were to go with a 2-2.5" block, would I need to replace the rear shocks. NorCal Trucks did have a universal 2.5" block though.
