MAHLE CLEVITE Valve Stem Oil Seal Set Part No: SS46021
$17.55
The Mahle Clevite SS46021 valve stem seal set is designed for dependable top-end oil management in heavy-duty engines. Valve stem seals keep excess oil from entering the combustion chamber; worn seals can cause start-up smoke, fouled components, and higher oil use. SS46021 uses OE-grade materials and precise sizing to maintain a stable seal through thermal cycling and continuous workload. Install during cylinder head refreshes, valve jobs, or full overhauls. Available from Wofford Truck Parts.
Specifications
For professional diesel head work, the Mahle Clevite SS46021 Valve Stem Oil Seal Set delivers OE-equivalent sealing at the valve guides. These seals are engineered to meter oil correctly—allowing lubrication of the stem while preventing excess oil from being pulled into the chamber under vacuum or boost. MAHLE/Clevite manufacturing emphasizes heat-resistant elastomers, consistent lip geometry, and dependable press-fit sizing so the seals stay stable over long service intervals. Replacing seals with SS46021 helps reduce oil burning, limit exhaust smoke, and extend valvetrain durability. Sold by Wofford Truck Parts.
