I am looking to throw some lift blocks in my 99 4wd silverado and some torsion keys up front. The blocks i have no problem replacing, its the torsion keys i have never done before. Some people say i need a tool to remove them which i called autozone and a few mechanics and they had no idea what i was talking about. i am just looking for some help on removing the keys. Can i do it with a regular breaker bar and socket? or is there actually a tool to remove them? Any help is appreciated, thanks guys!
