    It certainly didn't make anything better, but I traded my ecodiesel before the emissions problems and it had pretty wicked delay even then. The emissions flash just made it worse when cold.

    This is why I dislike taking my vehicles back to the dealer anymore. A quick flash you potentially didn't authorize and it's no longer the truck that was advertised or sold.

    No surprise the nose feels heavy...that engine adds 400 lbs. to the front end. That's like installing FOUR plate steel winch bumpers on the front. The front/rear weight distribution has got to be terrible.

    Regen cycles are no biggie if you have a long commute. But for the average person with a <30 minute drive in to work it might become a pain.

    The DEF, DPF, EGR, fuel/water separator and the skid plates for the DEF plus fuel/water separator are adding weight primarily behind the engine...at least 100 of that 400 lbs.

    I think it's been stated that the engine is only about 100 pounds heavier, the rest is all the emissions stuff behind the front axle.

    No, as we were so busy doing burn outs and 0-60 sprints that it was reading about 18 :like:

    LOL: That’s what my 6MT/3.6 JLUR gets babying it on stock 33s in the winter.

    That sounds backwards. The DEF tank, exhaust parts, and a couple small skids are unlikely to add up to 300lb in the back.

    The DPF is probably the heaviest single component.

    As I recall the DPF tank is 5.3 GLS, so no counting the weight of the tank, just the fluid should be just under 45 lbs.

    This is the exhaust system from a Ram 1500 diesel. Cut the straight parts, shrink the fuel tank, and you have the JL diesel exhaust.

    The Wrangler Ecodiesel also comes with heavy duty axles, brakes, suspension, a door for the tank fills and who knows what else

    Most of the weight is in the engine block itself. Diesel engine blocks have to be inherently stronger than gasoline blocks since they compress rather than ignite to create combustion. That is my understanding anyway.

    I just know the front end of my Cummins was significantly heavier than the front end of my Power Wagon. The Cummins front end actually broke my floor jack that I had previously used for my Power Wagon. The Cummins also has much more nose dive like the OP described.

    A heavier front end may not be a big deal when it comes to rock climbing, but it is the last thing you want on muddy trails like we have in East Tennessee.

    The added 400 lbs is from the Dana 44 front axle that all Diesels get, the engine itself, DEF tank, extra exhaust and emission components, and skid plates.

    Out of everything, only the engine and upgraded front axle are up front with the added weight of the axle is moot so while I doubt there is an extra 300 lbs of DEF tank/exhaust/skid plates behind the front axle I could easily see it being around 200-250 lbs behind the front axle and around 100-150 lbs in front/over it since we can subtract the axle wight differences.

    When you say heavy duty axles isn’t the Eco running the standard 44?
