So that we're all on the same page here, you said and I quote, "I know it does effect it and really thought it would of been mentioned . It effects the steering as much as geometry brackets do which is worth mentioning". As in, I never heard a question from you, just a declaration of what YOU KNOW.
That said, I think you've confused me as being RockJock or someone like the installer you just quoted, both of which have an incentive to sell you on a product. Me, I'm trying to do is help people by showing them how to install something like this high steer kit and so that they can do it themselves.
As far as my feeling about steering goes, you're talking to a guy who owns 9 Jeeps, most of which are old and drive like it. Of the newer ones, my big Gladiator is running about 6" of lift and NO STEERING CORRECTION and I think it handles and steers just fine. Would it benefit from steering correction? Sure! But, to the extent that someone like you seems to think it will? Not really or at least, not in my opinion. But, I'm happy to tell you whatever it is you want to hear if it'll make you happy.
