I have the stock 20's with 33" diameter tires and have the 4.56 gears.

Would have went with 4.88's if somebody made them from the 8" front diff. Sigh.

i don't want to sound like a dumb a$$ but before i make a $600.+ investment i want to make sure it is a correct 1. i just would like to see tire size to gear ratio. i plan on building a custom lift of built upper &lower control arms with coil overs and maybe even bigger tires for trail use. please lets get more feed back. some one else is thinking the same as me.[8D]the 6.1 cam is coming soon also. it is also a quad cab. my 4 yr old loves offraoding.

I would say go 4.56's. The rams with stock 20's come with 3.92 rear ends, and those tires are shorter than the ones you are going to be putting on (275/60R20 which is 33" versus your ~34.5" tire). Also, I don't recall hearing of anyone wishing they had went 4.10's instead of 4.56's, but I have heard people wish they would have installed 4.56's instead of 4.10's
