From what I've read, the Duramax vs. the Cummins is a push. Many may not agree and will give the Cummins a slight edge but I'm not sure that's not just louder fanboys. The real powertrain difference that you get is the transmission and I don't think anyone would argue the Allison isn't the best in the business for the 2500/3500 series pickups. :thumbs:


I would argue that. Slap a number in a tranny and it is gonna hold that? No way.

Far more 5r110's have held 5oo hp stock than Allison's.

If the truck stays stock then you should not have any issues though. But really who stays stock?

And IFS is nice till you put a trailer behind it and a load in 4wd. Bye bye tie-rods.

BUT, they do ride nice on the highway.


New diesel in my driveway tomorrow would be a cummins. They have updated the the

Trannys and the look of the truck is far better than last gen.



Can't argue with the new HD from GM in the looks department. Some sexy stuff right there.



In the end, too many miles have been put on cummins engines with a far lower fail rate then the other two (ford being worse I admit) for me to think anything else if buying new. Like Jim said, lots of stories of 1/2 million mile cummins.

Why change a design that works?

Okay, so, um... I might be... Yeah, the Tahoe (gray one) may be on its way out and a truck on its way in.

Just wondering thoughts on Dodge versus GM diesels (Can't do a Ford. Sorry, J-Rod, they just be tooooo ugly for me.)

Pro's, cons, etc.

I really don't need a diesel on most days, to be honest, but now with me taking off two states away to ride the Teryx and living in a place where I'll likely be moving tractors, large loads of wood, etc., I do like the thought of the available power, easier towing and good MPG's. I have buddies who already have them and who haul my stuff now but I hate being dependent on others for stuff like that. I like to be at my own mercy. :)

Anyway, let the flames begin.

Saw a really nice 2012 RAM 2500 Crew in white the other day. :drool:

Honestly, I think you are on the right track. My neighbor had fords, he has now switched over to Cummins and Duramax. He likes his Duramax more but would buy either truck again.

I would imagine that you'd be looking for a nice gently used truck. I would suggest staying away from as much emissions as possible. I think Cummins didn't get the urea till 2012. If you would be warranty conservative definitely don't get a truck packed with particular filters and urea burning exhaust gas..If you wouldn't mind tuning like J-rod did then get whatever fits your budget. If I was in search of a Duramax pre-emissions, I'd be looking at 2007-2010 trucks that are fitted with the LMM. It does have the DPF but it can easily be taken off.

The LMM is an awesome engine and you can easily find more high mileage trucks(500k+) than others.

The LML is the engine that adds the Exhaust gas. It is regulated by the government and makes you keep it full or your truck can become inoperative. When the fluid gets low the truck lurches into a 5mph limited limp mode, to keep you from polluting the atmosphere(right...)... I've never been in a position to have my truck become limited but I am sure that the situation could arise. I add 5 gallons each time my truck notifies me. It normally gives me about 750 miles to think about it. That's maybe 2-3 weeks for me.

Every sales person that I have ever talked to has told me if you want to keep a transmission under a dodge is to buy a straight up chassis cab truck. Since the factory doesn't know the bed configuration and how heavy of use it will see, they automatically put a heavy duty tranny in it(made by Mercedes?). I've seen a lot of Dodge tranny's gone bad and prematurely in my mind.

The Allison isn't the best but in stock configuration it is hard to beat. A lightly modded Allison transmission with a trans go Jr shift kit can be about bullet proof.

I may be mistaken but I believe the transmission in J-rods ferd to be the strongest out there right now. I've seen them easily take 700+ HP without a issue. You are limited to about 500 Hp, maybe 550 on a stock Duramax or Cummins transmission. Some might try to say it can handle 600-650 but they are not telling you how many times they have limped their tranny. Each time they limp, it only will get easier.


I would also throw out that the Duramaxforum.com is one of the best sites out there for the DMAx...

If I was buying a new diesel it would be a cummins. The truck can handle the aftermarket items without to much worry. They look nice, (not as nice as the GM) but the engine's I feel will hold up better. I own a 6.0 F250 and have almost 200k on it without any problems, but if I could, I would switch to a cummins because of the aftermarket possibilities without tons of engine work.
