Agreed with what was said above. The aftermarket keys are a sham, I've ran my truck for over 150k miles with cranked factory keys and never had an issue. Even have original axle shafts. You won't need shock extensions because the suspension is still within its travel range. You could benefit from a set of bilstein 5100s for it, makes a world of difference. It's odd that your 285s rub, I cleared 285/75s without even turning the keys up, then I got my 315/75s and turned the keys up most of the way and they only rub just a little.
