Just wonderingWhy couldn’t you?
Just to make the truck leveled. I have a stock rear and now the front is a little bit highAdding wider tires?
What would be the best size block to go with a 2 inch spacer?Oh! You're talking about suspension blocks. I thought you were referring to wheel spacers that go between the hub+wheel to reduce tire rub in the well. Yeah, you don't want the front higher than the back. If you like the front being up why not add blocks to the rear to lift the whole truck and level it?
