How can I figure out what gears on in the truck im lookin at? Its an 04 Crew Cab Short bed, with an auto. I know where to look on Dana axles but these arent Danas.

 

First place to look is the glovebox. There is a sticker showing the additional features for the truck. There are no tags on the aam axles. If you are dealing with a dealer have them get the vin # and pull the build sheet on it.

 

Thanks, Ill check the glove box. But if it helps Im doin 66 mph and 2000rpms.

 

If you have stock tires & wheels , it sounds like they would be 3:73s , the other opp. would be 4:10s , if you truck was older [ don't know when changes ] 3:54s , 3:55s.

 

sounds like 3.73's, but ck the glove box.

 

Glove box said 4.10s I have no need for that deep of a gear. What gear options are available for this truck with an auto? Can I get 3.54s, or am I limited to 3.73s?

 

If it's auto get the 4.10, stick get the 3.73!!! Unless you aren't going to tow anything with it get 3.73

 

3.73 or 4.10 is it.

 

I tow 50% of the time with 3:73's They will get the best mileage and roll down the road nice 2000rpm = 71MPH ish. If you tow heavy and quite a bit then IMHO I would go 4:10's and a 6sp. But you might not like them doing 75 empty.
