Can’t argue for $20
Fits 02 24valve Cummins like a glove. No leaks, and a fraction the price of a Cummins OEM

Direct replacement
Install was straight forward. They seem to be holding up just fine. I haven't had any leaks. I have 40k miles on it and no complaints. I was a bit skeptical when ordering but no worries they are just as good as oem so far. They fit as well as the oem.

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.

Seals
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.

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.

Perfect fit goof for installed easily. Needs an installation tool also available on Amazon for a reasonable price

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.
