Boom. Gears here I come. Made a deal with my buddy and am going to leave the truck with him for a week or so when I move

4:10s or 4:30s if I can find a reverse cut 8.8. I would do 4:56 but I don't want to ever go above a 35 and I don't want to pull 2400rpm down the freeway

Ask fx4 what he's running rpm wise
#6695
Just go 4.10 and be done with it. If I were to do it again I'd put 4.10s in.

my 4.56s and tune put my rpms at 2300 or so at 75. The tuning helps a lot as far as that goes. Puts my highway speed right in the middle of my power curve so I get pretty good Mileage on the interstate, even with all the hills I drive around on.

Are those gear-tire charts off? Because they say on the chart 4.10 and 33s would be equal to stock,4.56 for 35s,4.88 for 37s 5.13 for 40s etc.
