    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.

    I'd advise against it... just think what would happen if one happened to kick out when your going at highway speed. If you are dead set on doing it at least get them welded together before installing them.

    Stacking blocks is never a good idea, very dangerous, welded together or not.
    Check local vehicle laws, in some states this is actually a vehicle violation.
    If you want lift spend a little more money and do it the safe way with springs.
    Many aftermarket mfgrs also recommend you remove the factory block for spring lifts due to shifting concerns.

    Wouldn't that seriously affect the drive train geometry to a point of poor performance and early or premature wear?

    Why not just purchase a 5" block so you have it done safe the first time?
