ATLEAST 456s. you are thinking about bigger tires already...gear it once and gear it for them.
You might have 3.42 gears if it kicks in and out of od. check for the code
GU6(3.42) or gt4(3.73)
4.56 on a nine hour trip....:insane: have fun lol that might not be the best on gas for ya... idk what I would do dudeIf i drive for a while with 4.56's on my 33's will my milage be conplete shit? I drive this thing A LOT, and will be going to the Ozarks(9 hour+ trip) at the end of July pulling my boat.
And yes, i am going to fix it before it gets worse, it is really bad and slams and knocks around like crazy, tranny is shot too and is being replaced as well. I have parked my truck until i can figure out what setup i am going to run.
how you drive has a lot to do with it...most people wouldn't think my gearing set up is too great, SMALL 36s and 5.13s, but as long as you stay the speed limit on the highway (shouldn't pass it anyway if you are worried about mileage) then its not gonna hurt anything.4.56 on a nine hour trip....:insane: have fun lol that might not be the best on gas for ya... idk what I would do dude
I'll just second this notion:imoATLEAST 456s. you are thinking about bigger tires already...gear it once and gear it for them.
That's what I'm running. my 35s measure 33" and I've got yukon 4.56s with a yukon lsd. On the highway, i get about 13 doing 75 mph. If i was really concerned about the gas mileage, i'd drive 65 and avoid passing people. In town, it pulls great. I haven't pulled a trailer yet, i will in august, but there's plenty of power on tap in town.If i drive for a while with 4.56's on my 33's will my milage be conplete shit?

how fast do you drive on the interstate?My truck already gets 12-13mpg at best. Even when i had little 285's all highway it was only 13.5. That is why it is so hard for me to believe everyone who gets such great milage, If this truck drops below 10mpg its gone, the reason i dont drive my Dodge is because it averages about 8-9mpg.
my truck completely stock except for a borla muffler got 20 mpg doing 70-75 on the highway.My truck already gets 12-13mpg at best. Even when i had little 285's all highway it was only 13.5.
