3.73 if you are gonna do alot of highway drivin. but if you dont then i would think 4.10's would be optimal. i am having mine swapped to 3.73's tomorrow along with putting in an eaton posi.

i just went from 42's to 73's. i feel a diff. most people say they can't. i can. i have a decent amount of mods i think. 01thunder said it right, if you plan on driving a lot on the hwy then 73's will be a nice choice. however, if they hwy is not a problem with you, and all out performance is what you want, then go 4.10. to some people, mileage and rpm rev isn't a problem. hope we helped you out..

What kind of tire are you going to be running. If over 29", just go with 4.10's.

i am running the stock size tire and have major tire spin with 3.73's. haven't track tested it yet. will do probably next weekend. good luck with the gear change. lance, do that gear swap, i'll still stomp you when i am done. lol. then again, you have 20 inch wheels. so that will end up being a 4.10 or 3.90. might be a damn fine choice for you.

Good choice. The only reason my I have 3.73's is because that is the gear my truck came with from factory. It would not be feasable to go from 3.73 to 4.10. However, if my truck would have come with 3.42's, I would have changed them to 4.10's.

Go with the 4.10s.Just make sure you have a good posi and decent tires.
