Do not see the pictures.

Sorry I had to edit some of the pictures and go back to 2006 to figure out how to do that on this forum. Nothing special just a work truck that’s going to pull a trailer every day.

Congratulations on your new truck nice and white you have the best Cummins 6.7 HO may last for one million miles!

That’s nice. I like my chrome and roof lights. Long may she run!

 

[Beach Bomb]

Thanks for the kind words guys. I’ll get a better picture tomorrow now that I know how to edit.
With the Jake break off and driving down the highway when letting off the fuel the transmission seems to make a roaring sound. Other than that so far I like the truck.

It only shows CP4 in the parts system for 2021, so if anyone can get a VIN we can see if it shows up by VIN.

Just took delivery on a’21 2500. Which character in the VIN tells what pump it has?

Just look under the hood.

The sticker with the emissions is somewheres in the engine bay, that's the interesting one with all the codes on it.

Not on this truck zero information about anything!

There isn't one on the side of the head too?

I’ve looked everywhere I think they were too busy shooting these things out the door.
A good friend of mine has a 19 and the sticker that’s pictured above has all of the information about horsepower.

Maybe they stuck the emissions sticker on the underside of the hood.

There will be 2 stickers like always. Possible but doubtful, the pump info will be on the valve cover sticker, but the one I asked to see has been on the hood near the right side/ hinge. That seemed to have some strange info on it, and I asked to see that.
I was looking at some trucks online, and some that I saw were ‘20’s and were still enroute so I couldn’t see the window stickers on those.

comrade - bought a 2018 2500 g56. at 6k the clutch went out. got it back few days later, broke again. clutch out. then 30 days at dealer. im a contractor and same as you no truck no work ( or limited work ) thankfully i have a 2001 2500 that barley works anymore, and a 1995 subaru wagon ( that has never broke in 296,000 ) i will say ram did step up and make my january truck payment, which i find honorable. i find the parts availability / shortage somewhat concerning these days, but everyone will blame it on the china flu. merry christmas. cheers!

Can’t find any stickers with pump information but did confirm I have a CP3 unit. Truck build date is 12-20.

You can download Cummins Quickserve App onto your Smartphone, plug in your Engine Serial Number (ESN), and you will get all the info about your engine you need to know.

Cheers, Ron

The 2021 Cp3 being retrofit may be unlikely since the timing gear cover and pump gear are different

That's why I think they are spinning that 2021 CP3 faster than a 2018 CP3... In it's form up to 2018 it was already under utilized so bumping it up a few rpm wise is a no brainer. I doubt Bosch made a bored or stroked pump only for FCA Cummins.. Bosch just said to FCA "spin it faster for wanted results".

But they don’t need to. Countless people are pushing their stock 03-18 CP3’s harder than needed for the 21’s power output.

I’d be more surprised if anything was different gear train wise over an 18 than if not. I wouldn’t be surprised if there where some internal mods to help longevity with sustained higher pressure, but even that’s not a guarantee. If you look at the 6.7 vs 5.9 rail pressure maps the 5.9’s ran a higher average pressure despite the 6.7’s higher peak pressure.

The timing gear and cover are different from a CP4 for sure, but I doubt from a 2018 CP3.
