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 an OEM-quality replacement seal kit engineered for high-performance Hemi engine builds and restoration work. This 16-piece set addresses a critical maintenance need for Dodge Gen-3 Hemi engines (2009–2021 model years), where original valve stem seals degrade over time and cause oil consumption, blue smoke, and reduced compression efficiency. Whether you're rebuilding a cylinder head, performing valve work, or maintaining an aging Hemi engine, these seals restore proper oil control and engine longevity.

Each seal features a positive-stop design with a steel body and Viton elastomer material, providing superior heat resistance and chemical durability compared to standard rubber seals. The 5/16-inch valve stem diameter and 0.470-inch guide bore are precision-engineered to match Dodge Gen-3 Hemi specifications exactly, ensuring a leak-free fit that requires no modification or machine work. Viton construction withstands sustained high temperatures typical of Hemi combustion chambers while maintaining a reliable seal, preventing oil migration into the combustion chamber and keeping your engine running clean.

Technicians, Hemi engine enthusiasts, and professional rebuilders rely on COMP CAMS valve seals for their precise fitment and durability across all Dodge Gen-3 Hemi platforms—including Ram trucks, Chargers, Challengers, and Jeeps. Installation requires standard valve seat removal and guide work during a cylinder head rebuild; proper installation ensures immediate oil consumption reduction and restored engine performance. This 16-piece set provides complete coverage for a full engine rebuild.
