04 5.3. I have the 3.42 gears in my rear end and want to upgrade. Could i get more performance from gears with a higher ratio than 3.73, like the 4.10? Or would it be better for performance and my tranny to go with the 3.73? Thanks

I thought the 4.10 was if you towed a lot...

that could be.....cuz they put the 4.10 in the heavier duty silvers. I will prolly jus go with 3.73s to be sure nuttin bad happens.
