RAM 2500 Cummins Diesel **HEAVY DUTY Mechanic Review** | Is CUMMINS The BEST?

The Cummins is the best Diesel engine option in a heavy duty pick-up truck. I review as a heavy duty diesel mechanic this 2021 RAM 2500 Cummins Diesel and explained why the Cummins is the better diesel engine between the PowerStroke Diesel and the Duramax Diesel.

What I Use:

My Camera Gear:

What is going on guys, this beautiful 2021 RAM 2500 Cummins Turbo Diesel is my good friend Ryan truck and I wanted to share my opinions on this awesome engine. first and foremost I don't mean to hate on GM or Ford but their diesel options, the Duramax and the PowerStroke are simply not as well built. they are consumer build engines whereas the Cummins is a commercial use engine built and designed for round the clock off-highway use. this results in a very strong reliable engine.

The Cummins is an Inline 6 engine whereas fords powerstroke and GM duramax are both V8's. now if you know anything about big trucks and towing you'll know that just about every engine on the road today in those semi trucks is an inline 6 and there is good reason for it. Inline 6 engines produce more torque at lower RPM's because of their natural undersquare design resulting in longer crank throw and more torque at slower engine RPM. which is exactly what you want when buying a heavy duty pick up truck!

not that V8 diesels can't make lots of torque in fact all things the same a v8 and I6 will make the same torque numbers but a V8 will make its torque higher in the RPM band then an inline 6.

this also means that a v8 will rev higher and faster making it actually a better engine option for a fast engine and a fast truck. so if you are looking for a quick truck a V8 option is a great option! Not that the Cummins is slow but again all things the same a V8 will be a fasting reving engine resulting in more speed in theory

the other major reason why a cummins engine is soo good is because of its reliability and the fact that it was over engineered for use in a pick up truck! these engines were originally designed for off-highway commercial use and were going to be used mostly for CASE tractors. in 1989 Cummins struck a deal with Chrysler and the rest is history. but that same commercial engine is used today in RAM 2500 trucks.

how many medium duty truck do you see rolling down the road with a duramax or powerstroke engine? None. that's because they are not meant for heavy duty use. those engine are fine, there's nothing wrong with them and they will serve most people just fine! but the Cummins is simply a stronger engine built to last.

so to conclude the Cummins engines are great and they are the best engine offered in the pick up truck market!

Im a huge Cummins fan, but I feel people also forget to mention that its 2/3's of a v8. That's 2 less injectors I have to buy, that's only 1 head gasket, not 2, one. Its in a straight 6 formation, I dont have to worry about disassembling the intake manifold or going through a mess of pipes, the turbo is right there, everything is right there. I don't gotta worry about glow plugs. There is 2/3's the moving parts to worry about. Cummins is in fact superior

The 6.7L Cummins is a well built engine like you said and it can be even more reliable when you do a full emission equipment delete

[sideshowbob]

Definitely can agree, I've had my 2006 Cummins 2500 for 14 years and the only things I've replaced on the engine is a water pump and injectors....That is it and still going strong, my truck has 335, 000 miles and is awesome

Been a technician for 27 years. Just got my first diesel truck 2021 Ram diesel and love it! Took me years to buy one but for my hard earn money and experience the Cummins wins. 6 in a row ready to tow!

[kenbtheman]

I think the best truck would be a Cummins engine backed with an Allison transmission in a Ford body. Just my opinion.

[themotofixery]

I own a 2017 3500 limited single rear wheel and I absolutely love it. I pull double trailers. A 30 foot fifth wheel and enclosed utility trailer behind that. 65 foot total length. Almost completely stock emissions intact. It's a beast!

[supersonoma]

Can't forget about having a manual trans option up to 2018. I've got a 2016 cummins with a G56, deleted and tuned with a south bend clutch. It's amazing! My new favourite eng/trans combo. It's a pleasure to tow with and rev match downshifting with the exhaust brake puts a smile on my face.

We have both, Ford F-250 Super Duty's with the 6.7 Power Strokes and Ram 2500's with the Cummin's diesels. In face we have ordered 30 new Ram 2500's with the Cummins and so far received 17 of them. We pull Big Tex Goosenecks and some heavy car hauler trailers. I have not ran into any issue pulling anything with either of the trucks. What I have noticed is the Ford has way more get up and go on take off or when passing anther vehicle and has a smoother ride. Also two of the new Dodges are now in the shop with less that 6000 miles on them. They have fuel delivery problems due to the fuel pumps. From what I have been told this is a issue that Stellantis is going to address with a recall but it don't hemp much when I have trucks breaking down in several states.

Thanks for confirming my experience and explaining the technical reasons why my 2006, Ram 3500 is such a great truck. So glad I bought it 18 years ago. It’s still going strong.

[cooperbrown]

Good video and you are correct about this engine. Ive had three Ram 3500 in the past and still own one today. All were high mileage trucks that were all deleted and caused no issues. The same cannot be said about the trucks but the engine is flawless.

Truth!!
I’ve been driving Cummins pickups for years. By far the most dependable, longest lasting pickup engines ever built. I have several 5.9 engines with 600k and still running good. I also have had several 6.7 engines that have been just as dependable as the 5.9.

[jerryfuentes]

Cummins engines are so easy to work on and that true commercial diesel sound it makes just love it..

For a couple years I installed these retrofit 4 cylinder Cummins engines into bread trucks to replace the underpowered Ford 300 straight 6's. I was really impressed with the power output. They are a little weird when adapted to a gasoline engine stick shift transmission but I liked them. As my boss at the time told me the 4 banger is identical to the 5.9L straight 6 just missing front and rear cylinders. These adapters for the transmissions looked like massive wasp nest, guess they can adapt to anything for real.

[johnlong]

Thanks and yes, I totally agree using a 12 valve 5.9 Cummins with ~ 300+ hp and 500.000 + miles on it!

[tomfrantz]

My Aissen in my last 2014 was perfectly paired to the 6.7. !58K and zero issues. LOVE the Aissen and Cummins pairing. I heard the new ones are improved. I hope they are not improved in a way that would make them less reliable...

[DarkHorse]

I’ve driven cross country quite a bit. The majority of HD pickup trucks on the interstate towing big loads are Rams. You see them way more than any other truck on the road.

[Rift]

Can’t argue with this. I’ve owned a 5.9 Cummins and a 6.7 Powerstroke. Love them both.

[stevenpeterson]

Awesome video man!! I wish Cat would make a small displacement 4 cylinder diesel engine for light duty trucks. I had a Cat C-15 in my dump truck and that engine was indestructible!! I ran that truck at 2000 plus rpms and drove it like I stole it!! Honestly I think Cat is a better engine then Cummins in Semi's.

[shaunarchangel]

They are most likely the most dependable. They are more fuel efficient as well . The powestroke though is the most powerful diesel engine in the pickups. Also the most costly to maintain compared to the cummins, which is easier to work on to.

I currently work in truck rental, and I have driven all three of the 2500 diesel motors between ford, gm, and ram. Now prior to working at this job, I would have never even considered getting a diesel powered anything, because I was in love with a gas V8 for my truck, and that's what I wanted to stick to. But then, one day, I drove the ram 2500 with the Cummins.

O.M.G.

I have not been shopping for a Ram 2500 4 wheel drive with the Cummins LOL not only is his engine better driving than the general motors or Ford competition, it's better in terms of power and performance in my opinion then even a gasoline V8. Not to mention, it also is more fuel efficient, and OMG the sheer amount of pull this motor has with all of that torque, it's completely addictive. I don't tell anything, I don't haul anything. I like to go off-road, and that's about as heavy duty as I get with a truck. With that all said, I think the ran with the Cummins is a perfect truck for the job
