Cranking Keys on 6" RC Lift?

[CJ Rodarme]

Who has experience with cranking the keys or adding leveling keys to their lift kit. I'd like just a hair more up front, and the keys are maxed out. I have 20x12s on 295 Toyo ATII's and I'm concerned with front end wear, and I don't want to make it worse. I noticed as well that my drivers side is 1/2" shorter tire to fender, is there a way that I can get it exactly level without a bunch of trial and error? TIA

Get some Ford keys. They're indexed just a smidge more aggressive, but not to the point where you're going to gain like 2" completely decranked like you would with cheap Ebay keys.
