Duramax Or Cummins?


Im planning on getting a new to me used pickup this spring or summer. Ive always been a GM guy and always had good luck with them.

Dodge owners are always bragging about how awesome their cummins is and I made the mistake of buying a dodge. Ive got more money into that thing then I can ever get out. But since I have a family now I need to cut my losses and get a extended cab or 4 door.

So Im leaning very heavily towards the duramax but Ive never owned one. The few people I know who have only say good things but so did the cummins guys.

Ive been kinda looking around and came across a dodge that someone put a different bed on so it looks goofy but otherwise a clean looking truck and Ive been thinking about a utility bed so the price may be right. But Im not sure I want to risk buying another dodge.

Re: Duramax Or Cummins?


What years? That's a big thing with used cummins or Dmax.

I just got this. They are brining stupid money for 20 year old trucks.

Re: Duramax Or Cummins?


The engine is probably the last thing to give you grief on these trucks. I'll never forget my friends 2006 Duramax which was brand new... constant stream of problems, changed every part of the engine under warranty including injectors... eventually found out it was a bad wiring harness after a year of chasing ghosts.

Re: Duramax Or Cummins?


Front suspension on the dodges are not good ,seems like guys are always rebuilding them. And new ones seem to have enough injector problems too. Duramax they says you want to use good , like OEM , fuel filter to keep the fines out of the injectors which kills them. Also IMO it seems like when guys start chipping the diesels to much that is when the problems start showing up.

Re: Duramax Or Cummins?


Dmax injectors are 800 each.

Cummins are still the cheapest engine to work on compared to dmax or psd.

The new 6.7psd is over 400hp and really close to 1000 ft/lbs. Of torque.

Crazy.

The reason I bought my dodge is you can get around that much torque with less then $1000 in modifications and it supposed to improve fuel economy.

It might be a great engine other then its always leaking oil but the rest of the truck is poorly built compared to my gmc.

I have a buddy that bought a 97 3500 4x4 dodge dually, 12 foot flat bed and a 5spd.

He put one clutch in it and rebuilt front end twice in 450k miles. Sold it for 4k last year.

It is a lot of engine in any pickup truck.

You don't want a 53 block, and the 02s had a poor fuel pump.

Re: Duramax Or Cummins?


Sadly, I have an '08 Ram 3500. The Cummins is a great engine, been in big-rigs for years.

The problem is Dodge. They are just not made for working with. Already burnt up a tranny, and the guy at the Dodge specialist shop said that's just what they do. Forever. There is a RevMax tranny that is supposed to be bulletproof. Only $5,500.

Oh, and google "Ram TIPM". I'll let you discover that issue.

As it sits now, if you don't have to worry about emissions, like we do here in California, you're probably best getting an old, pre-emissions diesel, or a new, i.e., Ford, gas engine. You can get a 6.2 gas with a 4:30 rear-end and tow 15K with a Ford.

There is a reason nearly every fleet in this country uses Ford. But the PSD is junk as well.

The PSD in my 2000 Excursion has 350K on it. Still going strong.

The 7.3's were basically a 500k mile engine. The 6.0s were great if you dumped 6k into them, the 6.4s were junk. The new 6.7 seems to be a pretty rock solid platform.

Until they switched to the Japanese unit, the autos could never last behind that engine. Been going on since 1990.

The 5k built transmissions are worth it.

Yea, the 7.3 was great. My first diesel was a 7.3. I had a lot of glow-head issues with mine, but other than that it was great.

I had 6.0 that was studded and deleted. It was good I guess, but holy s#!t it was expensive. $2,000 for a HPOP. Grand for a Hydro-Boost. Etc....

If I keep this rig, I'll get one of those. I just got the rebuilt, and the way I drive, I'll prolly get 200K out of it.

If I win the Powerball, I'll get this. Just in Fire-Engine Red.

Re: Duramax Or Cummins?


I just traded in a ‘14 RAM 2500 with the 68RFE tranny at 104k miles. Turbo blew apart at 98k, covered by Cummins thankfully, then water pump supernova’d @ 101k. Tranny started slipping pulling my toy hauler at around 60k.
The emissions system was to blame for the turbo. They said I didn’t use it “hard” enough. Guess I should have just kept the 5th wheel hooked up to it full time. Whatever.
So now I have a ‘17 RAM 3500 with the AISIN tranny. It’s a MONSTER. I bought the super warranty and as soon as its expired the entire emissions system is getting deleted.
Every diesel specialist I know has all but guaranteed 500k out of this truck once that is gone.

Yep.

I can do a DPF and EGR delete, but I have to buy the stuff out of Oregon. Of course, it needs a tuner as well, or it will go into "limp mode".

Problem is, if I decide to dump it, I can't sell it in Cali with the delete, so I'm kind of in limbo right now.

Just got it back yesterday, another $2,000 in electrical repairs.

Re: Duramax Or Cummins?


I've had a lot of Cummins and Powerchokes over the past 25 years.

The only way I'll operate a modern diesel is buy it brand new and spring for the extended warranty. I have 44K on my 2015 Ram and it is fully warranteed until 150K. I have no intention of modifying anything on this ever.

If I was going used I'd stick with the older and simpler ones. If you need a crew cab then that limits you to Chevy and Ford. It seems that the mid 2000s and newer trucks in all makes were having growing pains trying to accommodate the newer emissions requirements.

I wish I'd kept my '02 Ram. It was a real work truck. I did have to do a lot to the front end, but once it was dialed in it didn't give me any further trouble. I traded it in at about 162K, 6 spd with original clutch. I never trusted an auto tranny until the most recent Ram trucks.

I’m a Dodge loyalist.
This new one is my 7th. The one I traded in for the ‘14, an ‘06, I should have never gotten rid of. That was the best one I had ever owned, including up the one I have now.

Compound turbos, suncoast tranny, stacked tuners, banks intercooler, injectors, pump, 5” exhaust from turbos back, cat delete... it would gaptise a Z06 stop light to stop light and not puff an ounce of black smoke. Also never broke a single part. Ever. Not so much as a fuse. Not to mention 25 MILES TO THE GALLON, 18 TOWING MY 18k# TRAILER. Seriously. I could kick the chit out of myself for getting rid of that

Edit: Worst interior ever, parts did break inside. Rode like a granite counter top, not lifted whatsoever. Would rattle your kidneys out. Crew cab short bed 4x4.

That's interesting. I thought the mid-'00 had all kinds of drivetrain issues, no?

Mine was the tranny. But that was completely my doing. I put it in the shop with 35 miles on it and had my performance guy start on the motor. The tranny took a beating. Ended up turning the underside of my truck into a salvage yard at a stop light brake boosting to race a new GTO. $6500 got me a suncoast and a billet torque converter.
That truck put 930hp/1450ftlbs to the tires. If there was another weak link, I’m sure I would have found it. Maybe I got rid of the weak stuff early and saved the life of parts down the line?

Add:
What is absolutely nuts to me now is my new truck with the AISIN is 400/900.... with no power adders. That’s absurd.

Thats what I like about my cummins, its very easy on fuel if I stay off the highway. The downside is everything on the truck is cheaply built like the transmission cooler lines as thick as a pop can. And it will knock your teeth out if you hit a pot hole.
