Alright i know i can add leafs and or blocks in the back my question is how big of keys and which brand and size exactly should i get to lift my truck. i want to get as much lift as possible without breaking the cv shafts. I already have a three inch body lift but i want my truck huge if there is a cheap way to do this let me know casue i am a college student and am broke most of the time.

 

There is only 1 kind of lift key, there is not multiple sizes. Check www.ebay.com or the FAQ2 in this section it has a link for some lift keys. You can only go 2-3in before the CV's get to a bad angle and the torsion bar bends.
