ZF Powerline for 2025 RAM HD Diesel

[AH64ID]

funny thing is payload on a duallyis alot higher than a SRW 3500, I think it is closer to 6000 pounds whereas the SRW's are more like 3500, and so are the tow ratings.. one thing worth noting on dual wheeled pickup trucks the speed limit the trucks have to pass to qualify on the J2807 tow rating is 35mph minimum instead of 40 mph minimum for SRW..

but at a certain point you have to realize that when a difference makes no difference, is there really a difference or do people just want something newer because it is different.

The payload difference is not that drastic, it’s a mere 1700lbs. My ‘18’s payload was over 4K and my ‘22’s is just under because it has some additional factory options.

Now that’s on paper, but those are the figures used for J2807. In the real world where payload/GVWR are less important the DRW can carry a lot more.

Looking closer at Nick's link, that is really the new picture of the engine.

Looks like some massive changes to the engine. Honestly, it looks much easier to service. Which as a potential future owner is a blessing.

If I was looking at a 25 my concern is that the engine will only be around for 2 years and then replaced by a major change. That’s not a long time, and what will that do for parts availability and future updates.

That's what I am worried about. Reminds me of the EcoD. 3 years of the Gen 3 and then they axe it. Hmmmm... good point @AH64ID.

I think the major changes are already done. If, all it takes from here on, is a crank change to 7.2 and misc to possibly change power levels, there won't be a big change. Just guessin, lol.

From what I’ve heard it’s a lot more than that for the 7.2, it needs a new cab for a moved firewall.

Is this the new oil or fuel filter ?

Yes, it's the new oil filter.

I have that same setup on my EcoD.

Pros and cons to it though. A big pro is no more fitting your hand in a wheel well and needing gadgets to remove the filter. Another pro it is less messy. Con, higher chance of gunk/debris falling into the system. Another con is that because it is upside down, the heavier particulates don't settle at the bottom of the filter.

I still prefer standard spin-on filters.

Expect MOPAR to only be selling this filter for the first year or two till the off-brands catch up.

No real info but the '25 6.7 is on Cummins web site now.

Page has already been pulled… whoops guess Ram didn’t want the ZF info posted yet

Yep, link doesn't work for me either. "Not authorized"...

Glad I took screenshots and posted them when I did... but I do want to give many, many thanks to Nick @NIsaacs providing the link when he did. Again, thank you Nick!

Cummins ought to come over here and realize that folks already got record of it. hehe

Goes along the lines of... "You heard it first on the TDR!"

Dang, so much for our $15 oil filters. $52 from Geno's.

Still could be the same basic engine. The 7.2 will probably need more/bigger cooling systems or maybe a bigger/better AC unit A firewall modification could be for any number of reasons. Maybe easier than modifying the grill area.

To me, it just makes sense that they are related, 6.7 v/s 7.2. It don't make sense for the big changes to the 6.7, only to be discontinued. Two engines of the same size, probably won't happen. It wouldn't surprise me if the block and head have the same part number.

 

[Ozymandias]

I think the same here, such major changes just for two years doesn't make any sense.

I doubt they are going to enlarge displacement as there is no real need.. and it is also major. I suspect the main reason they pumped it up to 6.7 litres from 5.9 was when they added EGR they lost some power due to that emssions stuff and adding about 10% to displacement made up for it.

15... try 5 dollars for those spin ons if u shop and dont confine yourself to OEM..
What a blessing to have used the same filter for 35+ years which is probably why they changed them to a new design.
gotta monetize it somehow and customers will have to buy a proprietary filter until the aftermarket gears up and provides alternatives.

It’s already been announced on some platforms, and it’s been in speculation for a while.

The main reason for the 6.7 is the same as the 7.2, lower cylinder pressures for emissions.

The EGR isn’t used at all during higher power requirements, so that eliminates its effect on power production.


It does seem odd to announce the ‘25 6.7 with plans for a 7.2 for the 2027 EPA requirements. The 5.9 and 6.7 have very similar bore:stroke ratios, but the speculation in this thread about the 7.2 just being a stroked 6.7 would make for a much bigger change in the ratio. It would allow for more low-rpm torque and possible increase in cruise efficiency, but decreased higher rpm performance which to me seems like it would be harder to compete with the driving feel of the V8’s in the other 2 HD pickups. Personally I know what’s better for how I use it, but Ram already looses customers to the V8’s just because people think 8 is better than 6 without any real knowledge of the benefits.

I think you are right on the money for the EPA2027 ideas.

As far as the 8 versus 6 cylinders, I agree with that too.

The I6 design Cummins has is a well thought out design that has just worked well for diesels in general.

I mean, most of the the equipment I own, rent, or operate for work has inline diesel engines. I've used 1 cylinder to 14 cylinder inline diesels from various brands. I rarely come across a piece of modern industrial equipment that has a V style config in a diesel.

 

[AH64ID]

Additionally, further reports I’ve read on the 7.2L state that it’s an all new engine not a 6.7L ISB refresh.

 

[Ozymandias]

Inline 6 cylinder is the gold standard in the Small Diesel world up to 20 Liters displacement. There is no discussion about that anymore.

In-line six cylinder to be more specific.

Similar to my 19 Jeep GC, it's MOPAR filter is made in CHINA. GRRRRR
