    Default how big fof a block?

    was wondering how big of a block you can put on the rear end between the spring and housing before you have to make other modifications like driveshaft, pinion angle and so on. thanks

    most 6" kits come with a 4" lift block for the rear and a 2 add-a-leaf. I would say that is the biggest you can go
