Swapping from 2.94 to 3.73 gears (4WD)

So I've read quite a bit on this today. Going to be going with a 6" PC lift soon. Will probably run the Toyo Open Country A/T II's in 35x12.50R20 (34.5"). I'm currently running those same tire in a 305/55R20 (33.2") flavor.

I am a 4wd and have the wimpy 2.94 gears. (I learned my lesson that the Big Tow package would have been worth the extra money at the time.) With going to 35's I have read everyone recommends going to 3.73 gears (for the most part).

I've been nosing around and want to know if these two things are what I need for the swap, and what else I will need to do for a successful swap? Thanks.

Not that I've ever read on here. Change an go as far as I know.
Would be nice to be able to keep cruise control, I use it a lot
Hope so
Yes you are correct, the 4wd models retain Cruies control option. The 2wd's do not.

When you purchase the gears, the page will show what pinion is required. I believe the 08+ trucks already have the correct pinion. But again, you can call and confirm over the phone, as they will be more knowledgeable about this sort of thing.

Good to know about the cruise, thanks
