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. Thanks Bob

 

that is not to big a diff, i think you will be fine you will just lose alittle off the line power

 

Get a FTVB!!!
