Gear Ratio

I need help finding out what gear ratio I have. I have 245-16's on right now. I have a 3 speed autotransmission w/ OD. The OD kicks in around 45mph. Any guesses?

RE: Gear Ratio

3.55's would be my guess, is it a standard Ram or a Sport? some sports came with 4.11's... you can go to http://www.differentials.com/calc.html to help figure it out...

RE: Gear Ratio

There should be a band or tag on the axle itself that will tell you what it is. You can also get all you info at the dealer by giving them your VIN. They should not charge you.
