Cummins: Everything You Need to Know

Back in 1981, Dodge unveiled the first generation Ram trucks and vans. Everything was fine and dandy until Chrysler realized the need for something to increase sales in Dodge Ram lineup. Competition in the truck market was very stiff between Ford and General Motors, and it was hard for Dodge to carve out a name for themselves in this market.

Today, the 6.7L Cummins has overcome most of it’s early reliability issues, however, it features even more emissions controls now than it did before. Even with stricter emissions, the modern 6.7L Cummins outputs an insane 1,000 lb-ft of torque thanks to various upgrades.

Notice how politicians even managed to ruin the reliability of an engine??? I’ve owned all Cummins series and the other big three. I can say my 12 valve was the most reliable and was like a grandad to the PS’s and Dmax that would always have little issues. Great video!!

I love the fact that ram still uses an i6 format. It just seems more industrial and utilitarian.

I sold Cummins engines in the industrial/construction market for 20 years and the B-Series really put Cummins on the map in the construction market. We had an engine that would fit into so many different types of equipment that we never had before, it really enhanced Cummins reputation in that marketplace. The reason the 6BT was so strong, it was originally a joint venture engine with J.I. Case for use in their industrial/construction equipment so it was built to last from day one. Unfortunately exhaust emission regulations, a necessary evil, has a negative effect on reliability/durability and performance and makes a good engine seem bad at times.

The 6bt was available in isuzu trucks in Asia as well
But it was mostly full sized truck that could carry around 20 tons at its back

Love my 95 12v any day! Yes it's a little slow to accelerate with a 24ft enclosed trailer and about 20k pounds combined, but its faster than I can shift it without the trailer. Should mention I haven't touched the p-pump so its bone stock and all original at just shy of 200k miles and I dont wanna mess with how reliable it is for me.

I bought my '98.5 Ram brand new and have done lots of work on it and modified the crap out of it. But had no idea until now that the pistons were aluminum. Hard to believe they can hold up to the heat.

[emilemenard]

if the 5.9 was torquier it was because of is multiplaform layout meaning that it was use on semis, tractor and snow blowers(my uncle worked in a company making industrial snow blowers and the 12v 5.9 was used at first and the 24v came later on even tho the 12v stay for long for it's simplicy and reliabilty)

You failed to mention the latest 6.7L uses a CGI block. Lighter than steel and stronger than the steel block.

I love my Cummins I’ve driven the rest and I love my Cummins

And here I thought I was going to learn about semi engines that really make up Cummins bread and butter.

The fact that almost every upgrade performance to the diesel engine in this era, while impressive, has led to the EPA cracking down on the entire aftermarket of "off-road" performance companies due to the "visual smoke" that is unnecessary, in this market, due to the "bros" that are the outlier of the typical enthusiast is a travesty to every enthusiast.

[richardbohm]

all three engines have their strengths and weaknesses. even though i am a ford guy, i prefer the 5.9 cummins over any of the others, with the navistar and powerstrokes next, with the exception of the 6.4, and the duramax bringing up the rear, though it also in its later versions is a very good engine.


many of the issues these engines have can be overcome with the judicious application of aftermarket parts designed to overcome the weaknesses of these engines.

The pic you choose for your thumbnail is a light duty Ram 1500 which never came with the Cummins.

[timothypotts]

The 6bt 12v is one of the best inline 6 diesel motors ever made, shame they have to keep changing/They used to fit them into 17 tonne trucks over here in England and did the job well.I have done work on them and the early motor with 170-180 bhp were built so strong you were not going to brake it, not like all this new crap

[noahlester]

98 24v cummins sport is my dream truck

[jamespuckett]

There's probably not a nickels worth of difference in Ford, Chevy, or Dodge anymore. They're all expensive and they'll all quit on you. I like them all as I've driven them all

Some random, unimportant #OSINT, just because I got curious where the shot at 11:45 was taken...
It's in Dallas, parked at the intersection of Swiss Ave and Good-Latimer Expy, zooming in down Swiss, next to the "Traveling Man Sculpture - Walking Tall" at 512
I got curious which city's skyline that was, and, well, found out *exactly* where the shot was taken

[bkier]

2000 24v
All stock from a performance/mechanical stand point and running strong at 240k

[rednecktim]

The 5.9 is a lot more better, it don't got any of that emmision bullshit, .and yes dodge is a lot better than the powerstroke and durshit

[xephael]

Good information but do we really need videos of douchebags in lifted trucks with low profile tires?
