I bought a 3" leveling kit for my 04' 2500hd and I havent installed it yet.. I was just wondering if this aftermarket leveling kit will be any different than what i've got my torsion keys cranked up to now ?? They're already cranked up all but 1/8" on each side, so will this aftermarket 3" leveling kit do anything more than what i've already done myself by tightening the oem torsion keys ?? Some kits claim to be 2", some say 3" .. I bought this kit from eBay for $47.95 and it claims to be 3". So what should I really expect from this cheap leveling kit?
