I'd listen to wandell he knows what he's talk about
don't waste money on aftermarket keys just crank your stock ones

if you are dead set on them don't buy the $300 readylift ones, buy $50 keys off ebay, their the same thing

Holy crap, people like wasting money on anything these days. If the package says it ok then it must be perfect. You need to get a book and learn how torsion based suspension works before throwing 200+ dollars away. the suspension works off of preload, the more preload the higher the truck will sit, by cranking stock torsion keys you are adding preload, aftermarket reindexed keys do the same thing except they allow for more preload, which is bad. You don't want to go any more than 1.5-2" on torsion keys alone, you can easily and safely get this by cranking your stock keys. if you actually think your gonna get 4" of lift by cranking aftermarket reindexed keys you are a fool, it will not be Driveable, even with 2.5-3" via torsion key lift you would not be able to align the frontend.

 

i think the manufacters belive you don't know you can turn up your stock keys
and that you will put in the new re-indexed and not crank them and some people are bought on that
