Looking at Brighten with 3.21 gears. What can I expect for power and fuel savings?

Thanks

Don't understand the question since the Ecodiesel was NEVER available with a 3:21 rear-end ratio. Never saw it listed for 2015 models either. That ratio is for the gas engines.


I have no clue how the gas engines respond with the different ratios.

Guess I'm just paranoid. I show Dealerships "options report" and it shows 3.55 gears. Window sticker shows 3.21 and I assume is a typing mistake. You know how it is, buying tonight and seeing truck tomorrow.

The dealer options is correct. I think they all say 3.21 in the stock printing.
Not signing any papers till I see the truck tomorrow, being brought in from los Angeles. Window sticker states 3.21 but dealer options show 3.55. I can find no where that says 3.21 is an option with the ecodiesel. How can I tell when the truck arrives tomorrow? Any thing on the vin? Seems to me in the glove box is something stating GVWR with such and such rear end. Sorry for some double posts. Still getting use to this smart phone.

Both windows stickers i have had, both showed the standard equpiment listed then as you read on you will see the option for the ecodiesel. After that you should see the 3.55 or .92 rear end. This was the same on the challenger i ordered. It had the 3.55 gear then in th option after the Super Trac Pack, it had the 3.92 gear ratio.
Shows ecodiesel then 3.21 gears. Read that window sticker several times and no where does it show 3.55.
Not sure what to think.

Let's see if this shows up. The standard equipment will show a 3.21 gear ratio. Under optional Equipment you will see the upgrade to the 3.55 or 3.92 gears

No where on that window sticker does it say 3.55 or 3.92 only shows 3.21.

Look at the rear axle. Around the drivers side should be a sticker wrapped around the axle with the gear ratio written on it. Standard gear ratio for a 1500 is 3.21. Once the diesel option is added, it automatically ups it to a 3.55. Only option is 3.92s.
Can you take a picture of the window sticker?

As soon as the truck shows up I'll get underneath and check for a sticker. I don't have the window sticker but will this afternoon and will get a picture. I feel more comfortable knowing I can check under the truck. Paranoid for sure but big money involved. Wonder if it's possible for factory to have installed wrong axle? Sorry guys for beating this subject to death. I'm also going to be sure to get in writing that they will give me redress should the wrong gears be installed.

So you are right, it doesnt say it. However the 3.21 is under the standard Equip. I am sure it has 3.55s

Thanks for checking matty. I'll get under the truck and look at the axle for the sticker. Truck should be in within the hour.
