    okay...i know most 3/4 ton stuff comes with 4.11's , and most people, when they change to 3/4, use the 4.11's for most any size tire..My question is what would be the difference between running 3.08's or 3.73's with say 35 inch tires and running 4.11's (which most people do) with 38's, 40's and 44's. Seems to me that if the gears would actually act taller with 4.11's and 44's than it would with 3.08s and 35's.


    you tell me.

    You could actually accelerate with the 3.73's or 4.10's, the 3.08's you could measure acceleration in minutes.

    You are right, 4.11s with 44s are actually "taller" than 3.08s with 35s. But who runs 3.08s with 35s and is satisfied to start with?!?

    "Most people" I know wouldn't think of running 3.08s with 35s. Most run at least 3.73s and prefer taller. I run 4.56s with 35s and will continue to run them with my 42s. I run 4.11s in my K20 with 36s.

    You really need 4.56 or taller if you want to run bigger than 38s effectively. Then again, it also has to do with your tranny combo.

    Check out one of the MANY gear ratio/tire size charts/calculators on sites like 4WPW or Randy's to get a better understanding of this.
