Product Details

The Victor SS45955 is an engine valve stem oil seal set engineered for Cummins diesel engines, including the 6C8.3, ISC, and ISL 8.9L engine families. Designed as an intake valve stem seal, it features a 114mm (4.490") bore and is finished in black. This seal set replaces OEM part number 3948578.

Key Features:

  • Intake valve stem seal set for Cummins 6C8.3, ISC, and ISL 8.9L diesel engines
  • 114mm / 4.490" bore specification
  • Replaces OEM part number 3948578
  • Prevents oil from the cylinder head from entering the combustion chamber
  • Controls valve stem lubrication and regulates oil consumption
  • Engineered to resist premature hardening, cracking, and leaking
  • Black finish; intake position

A failed or worn valve stem seal allows oil to be drawn down the valve guides and into the cylinders, causing excessive oil consumption and smoke at startup. The Victor SS45955 restores proper sealing to the valve train, ensuring controlled oil metering and reliable long-term engine performance.

Easy to navigate site

Experience was good, but the website froze when purchasing. I wound up buying the same item twice and have yet to speak with someone regarding a return and refund

Great

A dealership broke one of the parts of a rim I have on a car and needed a part in a pinch! Price was great and shipping was incredibly fast! Really happy with the selection and listing such a specific part, other sites just listed part numbers without pictures so THmotorsports made it easy to trust.

paid for 2 day delivery and took for days to receive after I was told could not ship to PO Box. That should tell you immediately when you type in ship to address on order form like all other business's do
