On my old truck, i felt the need to have it overcranked and it drove just fine like that. I wasnt close to maxed out, i had no alignment issues, and it didnt eat up front suspension parts like everyone thinks. Im not saying yours wont im just giving you my input through my experience. Not everyone can run 08 cvs and crank the tbars like a 16yo in his first truck. You must have a lift and if you have a lift you should be prepared to go through suspension parts at a quicker rate because larger tires add stress to everything. With that being said i was just offering an alternative solution that helps prolong the life of your cv shaft if you do wish to crank above manufacturer spec. Take my advise with a grain of salt.
