Good product!
2-years later, the truck still doesn't leak. Good product

Great Value
Item as advertised. Installed very easily. Also, of note, you do not need to purchase a separate seal driver with this item. The included driver worked fine.

Cheapest way for me to get the tools and sleeve in my timeframe, didn’t use the seal.
Ordered a name brand seal by part number, used this for the wear sleeve. Seal didn’t look to be of great quality… for reference I was working on a 93 W250 with the 12V.

Part fitment is great it comes with a seal installer which makes installation a breeze! Not had any issues with any leaks and this is much cheaper than a part from Cummins.

Works as it should

Good insurance against another leak!
I appreciate it when the after-market has a "fix" for a manufacturer screwup. This is one of those products. The seal depth tool that comes with this kit worked great. And the sleeve went on the crankshaft quite nicely using the harmonic dampener as an installation tool for it... no need to purchase that $40-60 installation tool when you already have one using that dampener.The one "Con" I see in this is that there are no "assembly instructions" that come with the kit, for example, which part goes where during the assembly process (there is one seal that is not "intuitive" as to where it goes). An "order of alignment" diagram would be helpful.

Not for a 12V Cummins
This does not fit a 97 ram 2500 12V Cummins - I bought one and it did not fit, thought maybe I got one out of spec, ordered another and brought to a machine shop to install on a press - it just chipped the paint on the timing case cover but would not fit. Apparently this is not a part to cheap out on - don't waste your time, I'm afraid you'll have to spend 12 times as much for the Cummins version.

Ne convient pas au modèle Cummins 5.9l
Pas la bonne pièce pour cummins 5.9L

Poor quality
Wear ring fit perfectly. The lip seal, however, was poor quality. Ended up ordering an oem part due to the lack of durability around the lip perimeter sealing surface and my choice to not have to go through another disassembly for re install.
