If I recall, I lost about 1000 towing capacity by going with the 3.55s. I'm guessing another 1000 with 3.21s. ...but I don't think it's possible to get an ecodiesel with 3.21s. Standard axle ratio is 3.55s. Check the rear axle. My eco has a factory sticker wrapped all the way around it and it shows 3.55. Should be on the drivers side.
3.21 vs. 3.55
So I have been assured by members of this board that ecodiesel comes standard with 3.55 gears and 3.92 option. Looking at window sticker shows ecodiesel ,3.21 gears and nowhere else on window sticker does it show an upgrade to 3.55. Truck is a Big Horn and got me to wondering. If by some fluke the truck does indeed have 3.21 and ecodiesel how would the truck perform? My tow will be 11 foot tall travel trailer with 5000 lbs weight. What does the board think of 3.21 gears? I'm wondering worst case scenario. Thanks.
