Valve Seal Set Viton Dodge Gen-3 Hemi 09-21

The Valve Seal Set Viton Dodge Gen-3 Hemi 09-21 from COMP CAMS is designed for Hemi engine builders and performance enthusiasts who seek reliability in high-output applications. Valve seals are essential components that help prevent oil from leaking past the valve stems into the combustion chamber, a common issue in performance engines that endure aggressive cam profiles and high RPM operation.

This COMP CAMS set is manufactured from Viton fluoroelastomer, which offers superior resistance to degradation from high temperatures and aggressive oil additives compared to standard Nitrile compounds. The seals are specifically engineered to fit the valve geometry and thermal demands of the Gen-3 Hemi platform, ensuring effective oil control and reducing blow-by gases that can affect engine efficiency.

This valve seal set is compatible with 2009–2021 Dodge Gen-3 Hemi engines, including various displacement variants used in trucks, Challengers, Chargers, and performance crate builds. Proper installation requires valve spring removal and stem preparation as part of a complete cylinder head service.
