Long time reader, first time poster...
I noticed that 4.11 gears are now available with the '04 Duramax. I have looked everywhere and can only find tow ratings for the Duramax and 3.73 gears with no mention of 4.11's. Any thoughts on how the new LLY power, torque and RPM curves would jive with 4.11 vs 3.73 gears for towing, mileage and performance?
I have 3.73 gears in my '03 GMC D/A 2500HD and it does just fine pulling my 12,000# fiver and get's around town nicely as my daily driver. I just wrote an order to upgrade to a GMC D/A 3500 Dually and chose 3.73 gears and still have time to call my dealer and change this.
