If you dont have the 4.10s installed i would send them back and get some 4.56s especially since you have a 35'' tall tire. You would get alot better off the line with 4.56s.

From what i hear 4.56s will actually help out the truck bc of how much less you have to get into the throttle. But if they were giving to you then, you cant beat that.

My next move will be smaller tires or more cubic inches.
