you say you have good friends that are in the business they must have crews that take care of all that shit for them... Even though I did some testing on the shocks and front arms I couldn't say that they would hold up. I know they are tested with many different tire combination but, they released for that specific tire size and I wouldn't change to a bigger size unless I was just driving on road. The direction I would go is towards the friends crew members if it was me... I am sure we can give you opinions but in my opinion you will get the best answer from the people that do this shit for a living...
Something tells me when I talk to my buddies who actually prep the truck they will probably tell me the same thing you just did. This is why I'm struggling with this the more I think about it. I'm really close with the owner of the team who is the driver/owner, and lets just say he is the kind of guy who says put em on, they will be fine. But then I know exactly what the two head techs will tell me, and lets just say it will confirm everything you just wrote. Thanks for the honest feed back, I know the correct answer, but the devil on my right shoulder keeps saying "Projects, Projects, Projects"...
