The Equipment Identification badge inside the glove box (sticker on the door) should say: DMF - Axle Ratio 4. 10

Go to the gear speed calculator and find your transmission and match up the speed to RPMs. http://www.klenger.net/dodge/general-reference/gear-speed-calculator.pdf

Ill admit Im not the sharpest pencil in the box when it comes to diesels, but it sounds like you do have a 4. 10.

Mine has 3. 73 and at the rpm s you describe, I show somewhere between 75-80. This is with stock 265 tires.

if you have a NV5600 trans then you have 4. 10's. G56, youve got 3. 73's, 48RE I believe even with 4. 10's your RPM's would be a bit lower.

You have 3:73 Gears in your truck. My 06 is the same way.

My 07 has 6spd with 3. 73 gears and runs about 2250 @ 70MPH.

2200 at 70 with 3. 73 and G56 is what mine runs.

3. 73s are to only ratio that you could get with the G56

Someone on here found 3:42's. They bought them but are waiting to install them (same 06 we have). According to Klengers charts, 3:42's will drop you from 2200 to 2000 at 70mph. Many of us are waiting for those that already bought the gears to test them and post the results
