The original tires you had on your truck were 30.46". Your new tires are 30.49". You don't need to recalculate your new gear ratio for tire size.

go with the 4.10's because there is no real difference in how they perform from a 3.73!!! my truck originally had 3.73's and i swapped them over to 4.11's and noticed nothing.

Where in the VIN does it say what gears I have and if I have the locking rear end of not? I know that when the truck spins it does spin both tires so I think it has a locker but I would like to know for sure. Thanks

I drove with the truck in OD today and watched the RPMs. It looked like I was running around 1500 or so. So that makes me think that I have a 3.23, I don't know for what reason I was thinking I has a 3.08. Anyway so going from a 3.23 to a 3.73 I don't think will make enough difference, so I will be looking at going 4.11 if I do anything. I will see how much harder it will come out of the hole after the headers and the tune. I think that the TM is hurting it more than anything. It is a slug out of the hole.

3.73s imo.
