Hey guys I bought a rough country leving kit and it came with a 3 inch block. I want to stack my stock 2" block ontop and buy new U bolts to gain more lift in the rear. My only concern is that my stock block is 2" across the whole block and the rough country block is sloped from 2" to 3". Is this ok to stack 2 nlocks together eventho one is sloped. Also I will weld the two together.
