[ConST]

As always with mods, there's the potential for them to void portions of the warranty. For example, if my shocks were to go tomorrow, Ford would probably argue the aftermarket springs aren't dampened correctly, thereby nulling my warranty. Of course I could always throw the stock springs back on if I had to go in for warranty work.

That said, if my fuel pump died, it could hardly be linked to me changing the springs or putting in a short shift kit.

With mods, you have to be willing to take the risk involved. If you don't want to take the risk, don't mod!
