Damn man, give some info like what your runnin now for tires and gears, manual or auto, and a what kinda lift you have to get a perspective. Can't give any answers till you have given some info.

Wouldn't need to do that even if you made up a signature with some info, and you need a avatar pic man......

Yeah, you have the 4.0 so 4.56's and 35's will work, where as me and a 3.0 might go with 4.88's cause my engine sucks..... Dreamin of the V8 though.......

Superlift+BL+35's+4.56's will work for you.......

Now go make a signature and avatar photo!

i dont think so.......that is nuts.......

an rpm calculator isn't as accurate as you think........the best way to figure out your new gear ratio is to use the following formula:

NTS / OTS x OGR

NTS = New Tire Size
OTS = Old Tire Size
OGR = Old Gear Ratio

and round up to the next lower gear.......

that formula is about the best way to figure out your new ratio......

i guarantee you with 4.88's and 33's you will get 4 gallons to the mile.......Scott D. (big04ranger) was running 37's with 4.88's and getting 16 mpg.....use your freakin head and search.....more than likely WE HAVE TRIED IT BEFORE!

a pretty crappy one.

[ (New tire diameter)/(stock tire diameter) ] * stock gear ratio = New gear ratio

34.8 / 30.8 * 4.10 = 4.63

I'm pretty sure that 4.56s comes closer than 4.88s

also

if you were running 33s.

32.8 / 30.8 * 4.10 = 4.36

4.36 is a long ways from 4.88

If you go with 4.88s.....good luck finding 4.88s for the front. If you're a 4x4 then you're probably gonna have to choose between a 4.56 and 5.13
