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.

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.

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.

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.

Great for the price
Works and fits like it should, to properly install this you'll need some other tools. I got my wear sleeve tool from thoroughbred diesel and I had the seal pressed in by a local shop that specializes in cummins diesels. You'll want some thread sealer like loctite 545 to go around the seal before pressing it in.Just got the truck back together I'll update if it starts leaking from the new seal.

Good deal if all u need is the wear ring
Once seeing the seal I ordered a name brand but still saved by using the wear ring
