Bottom line 3.73 is available on 08' 6.7L
I have ordered and we have many 3. 73, 08', 6. 7L trucks on our lot in single and dual rear wheal combinations. Instead of ranting about how awful Dodge, the Dodge web site, and your local sales staff are, lets try and pose a ligitamate question like is the 3. 73 axel ratio available in an 08', 6. 7L, auto transmission and get some answers. I suppose that's why most subscribe to TDR and why others spend hours researching to find legitamate solutions. Please check the other boards trashing the 6. 7 and join those sites if you just need to vent. #@$%!
JTWCummins window sticker does show that the 4. 10 is a standard feature, however, in his option catagory, by choosing the 6 speed Automatic it lists the 3. 73. Yes it is a little confusing, however, his also has the 3. 73.
When you actually order a truck through the factory website it lists the 4. 10 as an option with the 6 speed auto, but the standard ratio is 3. 73.
If you would like me to build/price out an order for you just let me know and I will personally go through the options with you threw email or over the phone. I do have a couple others to get to today so be patient.
If we did order a vehicle with specific options, and the options were not on the vehicle that was ordered (at our store) we would either refund your deposit, reorder the truck, or (if possible) add the missing option (such as tow mirrors etc. )
