Need Dana 70 out of a 2003 or above with 3.73 gears.

 

Dodge Ram didnt use the Dana 70 past 2002.

Are you after the AAM 1150?

Can try searching at www.car-part.com

 

I need a 3.73 Dana 70 or 80 with posi. If I have to shorten the axle tube I will.

 

Never seen a 3.73 geared 1st or 2nd gen Dodge Cummins truck.

All those Dana 70 and 80s I have seen, came from the factory with 3.54 or 4.10 gearing options.

That is except the non intercooled ['89-'91.0] 1st gen trucks, usually with automatics that had the 3.07 gearing option.

 

Buy a Dana 70/80 that bolts into your truck easy, or at least the right width. Re-gear it to 3.73. Why does 2003+ matter?

Theres more factory 3.73 possibilites if you move to that big AAM diff... 11.5" ring gear. The classic chevy 14bolt is also common in factory 3.73.

2003 and up, just makes it so you can not even get a Dana 70 or 80 anymore as they start using AAM that year for their axles.
So looking for '03+ Dana axle, in a gear ratio they never offered, sounds like you will be looking for a long time.

u2slow listed a couple options that would work to get what you need. All involve doing some wrenching.
