For some reason the buttons don't work for me. I am trying to figure out if what my gearing is - don't know if this info is available there.

That site will not give the gears of your truck. You need to request a build sheet for your truck from Dodge.
A build sheet would include all of the options that your truck came with when it was built, including what gears were installed.

Here is the page to contact Dodge for your build sheet. You need to put in an address from the United States, just make one up or google some place in the U.S. and use the address.
They will email you the information usually in a day or two. Most of us here have the info on our trucks from that page.
Just fill out the lines with the asterisks (*).

Gear info should be located on a sticker in the glove box.

Thanks to both of you - I'll check the glove box and I can get US location info from a client's file . . . (I'll ask him first of course!).

FWIW my indy mech just phoned down to the dealer and got me a fax of the build sheet for my truck. I must say I was pleased to learn that I do in fact have the factory tow package with the 3.92 gears, so my max trailer weight will be 6800 lbs. Well exceeding my expectations!

ah lucky you. I have the tow-package too but both my build-sheet and the shop that installed my Auburn say they are 3.55

Not trying to resurrect a dead thread but this seemed really useful but the buttons don't work for me.

Edit: Tried Google and this one seems to work till you try and click on what vehicle you're trying to view.

It's never a dead thread, this information can definitely come in handy sometimes.

I fixed the link up top, it has changed from time to time for some reason. Also try a different browser if it's not working correctly.
Like right now, I'm having trouble viewing it on Firefox, but it's working on Chrome fine for me.

Don't work

Try the link using Internet Explorer, I just opened it up fine and could navigate the pages.
And it will not work on Firefox or Chrome browsers anymore.
