Whats the build date on your 19?
Truck 7-19 Seems like engine was built 5-19.
I wonder if the 2019+ valve springs are any stiffer than the earlier 6.7 valve springs?
Normally the cam profile is more aggressive with roller lifters and then the valve springs have to be stiffer.
No idea. I definitely notice a wobble and bounce pattern on the cam after the roller leaves the top of the lobe. Also the axle of the roller rotates and has slight play on the Cummins lifter.

There is no pressurized oil feed though. Going to call Wagler and ask if the Jesels have a pressurized oil feel to the roller bearing. If so, will buy. If not, I鈥檒l just get new Cummins rollers.

Also, for @krs and @H3LZSN1P3R, timing case, cam, and lifters are made in USA.

EDIT: See post #89

So the Wagler Jesel lifters do not have that oil feed as they say factory ones don鈥檛 have an oiling problem. They state the wobble and bounce is from the hydraulics.

So, I ordered new Cummins lifters from Chrysler. About a week out max thankfully at $87 or so.

Just as a warning, I鈥檝e found that the lifters with 2 grooves machined in the upper neck have more wear than the later smooth style. IMO, It鈥檚 best to upgrade to the later style.

Also just my opinion, if anyone does this swap before 20k miles, I believe it鈥檚 OK to run the factory lifters and cam.

Slight discoloration is fine, but if it has discoloration plus scoring, I鈥檇 say replace.

I wonder what the price difference is between the Mopar/Cummins roller lifters and the Jesel/Wagler roller lifters?

Before I installed anything, I would want to closely compare and examine the original lifters with the new Cummins lifters and the new Jesel lifters, trying to determine which is the best choice.

And closely examine and compare the original camshaft and the new Jesel camshaft.

Knowing @cumminsturbofreak , that's exactly what he will do.. :)

$87 a lifter for Cummins. And as you can see the new smooth style looks great. For 12 is $1,044

$220 a lifter for Jesel. For 12 is $2,640馃樀

Since Jesel doesn鈥檛 use anything different for oiling, I鈥檇 only use it if going with stiffer springs.

This is how I鈥檓 reading a wobble and skip with hydraulics. I鈥檓 assuming that鈥檚 the noise we hear at 1500+ rpm. We鈥檒l see after the swap if I鈥檓 right.

I鈥檓 guessing this bigger lube groove (which supply oil to roller) is the reason the newer roller wears better.

my build date is 05/19, so def an early one.
Well if I don鈥檛 rent my lifter tool out or sell it to you, I may sell it to Wagler.

So anyone wanting to do this please let me know now.

I'd be going backwards on year models!
Every gen has one problem or another. FWIW, I prefer the new trucks with a couple fixes then old trucks with much more fixes.
