3.27 and 32s
like it says can i run 32 with 3.27 gears i will be on the highway most of the time so i will get really good gas mileage and i will just have to use 4L when i off road.
is all that right or will it be a real pain the a$$ or will i screw stuff up and need to regear i really dont want to regear so.????

yeah i know but on the highway its not guna kill my mileage its the ago old trick of old hot rods they kept the same gears but put taller tires on so they would produce more speed, which make the gear ratio which make your rpms lower on the highway which produces better gas mileage that y when going from 4.10 and 235 tires to 35 and 4.10 your gas mileage gets better because you raise the gear ratio and the rpms are lower on the highway and around town. 31s wont hurt me on the highway if anything it will make it a little better but going around town it will hurt me gas but i dont drive around town much so im ushualy always on the the highway. and when i off road i only use 4l alot easier to use.

Except.. the motor is going to be working harder to get to speed and to maintain speed. so it is kinda a trade-off. Ask some guys on here with 35's if their gas mileage got better with the bigger tires. remember a 35" tire is much heavier than a 235 tire. The 35 is also wider and more rubber on the road equals more resistance which equals less gas mileage and a bigger footprint to stop. what your saying makes sense on paper, but not reality.

Lowering the RPM the engine turns does not guarantee an increase in fuel efficiency. It's all about how hard the engine is working (and how much fuel the injectors are flowing).
Anyone with a ScanGuage or equivalent tool can verify this by going down the highway in top gear. Observe MPG. Now step on the throttle (but not enough to downshift an auto). Observe MPG. It will be lower with very little RPM change.
Most people who increase tire size by more than 15% regear soon after the tire size change. What's more, when they regear to say, 4.10 or 4.56 or 5.13, notice an increase in fuel efficiency. I did and I went from 32x11.5 & 3.55 to 4.10 gears.
Ford was the worst, particularly in the '80s, about using funky ring & pinion ratios like 3.08 and 3.27.

honestly with 32s, 4.10s will get you the best mileage. The age old trick of running the taller gear on the highway for better mileage worked great on carburated engines because of the way the carbs work and also because the engines tended to all have about 300 ft-lbs of torque at the low end at 1200 RPMs. With a modern fuel injected engine what has a torque peak of 2700 RPMs the most efficiant range of the engine is at 2700 RPMs when it will have to work the least.

well im a poor highschool kid and school to be a poor college kid so i need me gas mileage for the highway so thats y i would of with a 3.73 and i cant fit 33s with just a body lift so thats y that
Tim you have a 2.3 and 4.10s and 31s i have a 4.0 so im not worried about 31s on my truck if i had 4.10 and enought lift i would run 4.10s and 35s
