I did not regear my truck. its not that significant of a change. The 35s are definitely a big tire to turn over but my truck does it fine. Not a change in fuel mpg really either. I have 287,000 miles on my 4.6 so I dont expect good gas lol but still around 13mpg
I'm wanting to go to 315's on my truck. I'm running 285's now. Did you regear for the 315's or did you notice much difference in power and torque? How was the fuel mpg difference ? Any concerns. Thx buddy!!
