could i run 31's with 3.45 gearing or should i not

 

sure you could.. a 31 isn't that big..your engine will be able to handle it... i was running 35's with 3.27 gears for a while.. with my 4.0L though..tranny got a bit hot.. BUT 35's are a hell of alot heavier than 31's..

 

i ran 33's with 3:73's fine on the street. when i got in the mud it was a different story. so as far as running it on the street you should be alright, the second you take it off-road you'll see why you want a lower gear.

 

i also have a 2.3 liter engine if that makes a difference

 

i'm no motor head/ gear head by no means, but i do believe it would run pretty sluggish with a 2.3. i had a 4.0 in mine and at times, depending on where in the country i was driving, it was definitely struggling. but at the same time 31's aren't much bigger than what you're already running. so i'm not too sure...

 

not to rain on your parade by any means, but why do you want to go up to 31's? i think your tire size looks just fine, your truck looks badass

 

well i was just thinking about it and im gonna be lifting the front and i wasnt sure if it would look weird or not with the tires i have but yea i love my setup but i cant wait to level my truck out

 

it will look sweet all sed and done

 

So just so we are clear, running 31s on stock gears with a 3.0L should be okay?

i ran a set of 31" all terrains with my 4.0L with stock gears and it was fine. if i stopped in the middle of the road and backed up i could spin the tires even on dry pavement. i wheeled with the 31's and it wasnt too bad.

 

yea i have 2.3 liter 4 banger just so you all know

 

lmao. I wouldn't want to run 33's with a 2.3 unless I had 4.56 or higher (numerically) gears. Buuuut that's just me.

 

i ran 3.45 gears and 31's when i first put my 31's on and it wasn't fun. It was not good on my tranny at all, it ended up going out on me. Whenever i would go done the road it would shake like crazy cause of the tranny shuddering. Soon as i got it back i went to the junk yard got a old rearend with 4.10's and never looked back.

 

I have the 2.5l. I was running 31's with my stock 3.73 gears for a while. It was ok on the road but if I went and playing in anything real nasty I would have a hard time pulling myself through it. I swapped 4.10's in and the truck feels like it is back to stock power.
