I just added a 3" body lift and 285/75/16 Revo's to my SuperCrew. I have a 3:55 trans. Should I have anything done to it or will I be ok? The truck came factory with 265/60/17's. The guy that did the lift said he's seen alot of guy's mess up their trans after adding the bigger tires. I value you guy's opinion's as much or more than his. I posted this on the trans page also, but I think this is really a lift question. Thanks Bob

 

if you check there is not a whole lot of difference between the 265 and 285 except width your tranny is fine

 

I really don't think that going from a 32 to a 33 inch tire is gonna hurt your tranny. It won't put any more strain on it than towing.

 

what they said^^^^^

 

COFFMAN, do you have any pics?
