i want to do a 4 inch lift and 35s well im 99% sure im going to but whats the pros and cons of doing that?
sometimes a better ride (depending on quaility of the lift)
Longer tire life
quicker wear on steering parts (ball joints, tie rods, ect)
Easier to roll if you loose controll
harder to get in and out of, harder to load things in the bed
sometimes you can hook to gooseneck/fifth wheel hitched trailers
wider tires= more rock chips on your paint
If all you wanna do is 35s i would do a leveling kit and a f-350 rear block... great stance IMHO
:whs:you will hardly notice a change in mpg with 35's... just do it..
:whs:The OP is only asking specifically about going to 35s and a 4" lift. That is likely the number one non-stock setup run on these trucks. You're looking at about 1 mpg maybe 1-2 loss going to it but the real deciding factor is what your driving is broken up like. Is it mainly stop and go or is it mainly highway. Do you have a heavy foot on take off and brake early? But on the last, then again, if you do already its still the same ratio. I know of a number of 7.3 with 238/80 35" tires 4" lift that re getting at or very close to 20 mpg with a light foot.
If you have 4.10s and do highway driving mostly I would not be surprised with no loss.
8-10 mpg less just going to a 35" tire and 4 " lift? You have to be talking in terms of unlimited lift or tires range right? A 4" and 35" tires its not gonna happen no matter what the variables are unless its a serious mechanical issue and still it would have nothing to do with the actual lift or tire. That's near or over 50% loss or more loss than towing a 10K trailer.
Do you have a chip yet or air intake exhaust injectors? If you add the lift and tires you are planning and chip air intake exhaust you will likely pick up a 1 mpg possible 2 IF you drive with a light foot.
As a universal estimate of loss expect from 1-2 mpg with a 4" / 35" upgrade on average.
