good gears

[DurbElites]

i have decided that 4.10's are prob the way to go for my rig but the next question is that i am getting all the bearings for the diff. but do i need a new carrier bearing and what is a good company that has gears for cheap but aren't going to let me down. also will the 4.10's fit in the stock dana 30 housing and chrysler 8.25 housing

More than likely you have 3.07 or 3.55's now. Depending on the trans. For the front you will need a new carrier,gears & a master install kit. For the rear you need the gears & a master install kit. HTH. JIM.

how would i know what trans it is? i have an auto with a 4.0 ho motor and the tranny is stock and it didn't come with a tow package. any ideas what it is? i am also pretty sure i still need 4.10's to push my tires, i want to get (33X12.50) and still have pretty good gas mileage. now i get about 10-12 with 31x10.50's which is no good for me. any body out there with 33's and 4.10's also what mileage am i looking at

You have the AW4 trans., which means you have 3.55 gears in the axles now.
I don't know what kind of mileage you will get with 4.10's & 33's. I'm running 4.56's & 33's, I get between 15 & 17 on the highway. I really wish I had 4.88 gears. JIM.

I was told by people who know, "Your gears are only as good as your installer." I went with Yukons, and a trusted, well known local installer. No problems yet.
