lifting 5 lugs

ok so i put a 2.75 lift on my truck from fatbobsgarage.com its pretty awesome it comes with spacers add a leaf and rear shocks but what i was wondering was if i can stack another spacer on top of the other spacer in order to make more of a lift?

 

That's not a good idea. Your suspension is already in an altered state with the single spacer. If it was safe to lift it more with spacers, they would already make some that height. It is generally thought (although some like to argue) that spacers are not the best way to lift a truck, although they are cheap (I have the same lift as you).

They already alter the suspension in ways that can put more stress on other suspension components given the right scenario, ie. wheeling, and cause things to break. Adding another spacer would probably only make this worse. I'm not even sure you could fit another spacer. Probably wouldn't be able to get your alignment in spec either.

If you want more lift get the TC long travel kit but be prepared to spend some $$$.
