Was told that IF your truck has Hydraboost brake setup you can do the swap. BUT don't take my word on it hopefully some of the other guys that have done this swap or are in the process of doing this swap will chime in.
I'm tring to upgrade my suck a$$ stock booster to an 05 booster setup to improve the slush that I currently get out of my 03. That I can tell you will improve brake response and pedal feel.
