Solid Lifters for 2019+

10700 Views 190 Replies 22 Participants Last post by  Bad-Duvall
Been doing some digging and someone (Wagler) is finally offering a solid roller lifter conversion for 2019+ trucks.

It uses the factory ISB adjustable rockers, but just replaces the internals of the hydraulic lifter with a solid spacer. EDIT: Also uses custom pushrods as 2019 uses different ball on lifter and different length.

Seems like a permanent solution for when the hydraulic lifters go bad.

Of the actual cam and lifter install, I’ll do a write up.

Pulling the front end, no. Way too many steps.
If you can't pull the front end apart one should probably have a shop do that job then. Interested in seeing these new lifters

Yeah I did a tech write up pictorial for 3rd gens. It was a LOT of work to complete that write up step by step!

Looking forward to your results
So the 2019+ roller lifters are not able to be removed from the top and not able to be installed from the top?
And it doesn't sound like wooden dowels can be used to hold the lifters up for cam removal/installation like on the 5.9L engines?
And the timing cover still has to be removed to pull the cam?
And a special tool for installation of the roller lifters.

Good grief, Cummins could have made some changes with the 2019+ engines to make it easier to service the cam and lifters.

What were the guys doing on the 5.9L engines? Using 1.5" ABS pipe cut in a half moon shape and inserted in the cam bore to catch the lifters.
Then using string attached to the lifters to pull them back up into place?


With my luck, I would be ahead of the game to pull the engine oil pan as a 1st step to retrieve the inevitably dropped lifters!

Thanks for sharing the pics and info @cumminsturbofreak ...

Although my thread (5.9) isn't replacing lifters, I did use the dowel trick. I was brave and didn't use the PVC pipe cut in half, but I also pulled the oil pan. Lots of detailed how to pics in my thread.

Pretty much. As the special tool is out of stock, I’m experimenting with magnets holding the lifters up, but I may buy/make another tool once I have a lifter in my hand.

Lol the idea is to make newer vehicle less serviceable and more like cellphones. Last Cummins to have a tappet cover was the 98.5-02 24v.

Good luck with that.

It’s seems there was a hardening and hydraulic issue, but I won’t know until I get the lifters out. I’ll look over the rollers real good.

I’m contemplating spending more $$$ on going with the Jesel lifters too. Super expensive, but if this is the quality we can expect from Cummins, then I have no choice.

Also, I called Cummins and was refused sale of factory lifters as Chrysler has “exclusive rights” to sell those lifters.🤦🏻‍♂️

Stock valvesprings right?

Are any of the rockers galled or binding? Common on the early 5.9L CR engines..

I was able to get #1 lifter out with a rolled up price of cardboard.

Weirdly there’s only one parts number, but there’s obviously different lifters for intake and exhaust.

And the exhaust roller looks much better.

These lifters are allowed to wobble even with the keyway. This is because the machine notch in block is round, while the nub on the lifter is thin rectangle.

It seems those special Jesel lifters are superior in that regard, and they better be at $200 a lifter…

With that said, I’m torn if I should go all the way with Jesel lifters… what’s everyone else’s opinion?

i tend to overbuild things, and i always question if i’m going to miss that money vs piece of mind…With this job being this much of a pain, i would spend the money, definitely stings but i see it as a rock and a hard place currently. This reminds me, i’m going to drain an oil sample and send it out, if i need it sadly, i want some good evidence of cam/lifter material in my oil.

thanks for all the info on this! truly appreciate it
that cam wear is shocking. seriously.

I'd do the upgrade since you're literally balls deep anyway.

appreciate the documentation.

So does this mean we need to worry about cam & lifters like the HEMI boys do and start adding cans of Molly to the oil to protect the cam & lifters?

I would just keep an eye on it. If you get a borescope with flex head, you can easily check condition of your cam by simply pulling rockers and pushrods.

If you noticed, I have lifters in mine that have grooves machined in (RH in the picture). Seems like that is an old design, and it shows as only those lifters have wear.

And FWIW, these rollers are for Chrysler only. Every other ISB/QSB is still flat tappet if that says anything…

Roller lifters "shouldn't" require zinc, moly and other additives in the engine oil, even if this 2019 engine had really thin 10W-30 engine oil early in it's life.

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.

I can't imagine how bad the cam and roller lifter wear would be with stiffer aftermarket valve springs.


I haven't been able to find any info on Jesel Cummins valvetrain parts. Am I missing it on their website or on the Wagler website?
