Window sheet says 3.21 but i know ecodiesels came only in 3.55 and 3.92or 3.91.
I have towed a load around 14k without a problem but now im wondering what the ratio actually is?

It might be contained in your VIN. I'd check the RAM website to confirm.

3.21 is listed under standard equipment. Go to the options side and look and it will show the rear end as an option either 3.55's or 3.92's.

Driving down the road in 8th gear at 60 if your doing 1500 rpm you have 3.55's

Make sure you use caps for the letters

Do like we did in the old days...jack the back of the truck up getting the rear tire off the ground, make sure you caulk the front , mark the drive shaft and rear tire. Start the truck and put it into neutral. Rotate the rear tire 2 times and count the number of times the drive shaft turns. Close to 4 times = 3.92. Close to 3 1/2 = 3.55 Close to 3 = 3.21.

What year truck? 3.21 was not available in 2nd gen, only 3.55 standard and 3.92 optional.
