I am trying to find a good set of lift torsion keys for my 2005 1500 z71 for cheap. I have also heard that stock ford f150 keys will achieve a little more lift that the aftermarket keys. If that is true, where could I find a set of f150 keys for cheap? If not then has anyone found a cheap set of aftermarket keys and where? I have seen on some forums that people have found some for less than $50. That is what I would like to find. I cant seem to find any for less than $150-$300. Thanks for the help guys.
