8mm Triple Groove Valve Locks - Dodge Hemi

The 8mm Triple Groove Valve Locks - Dodge Hemi by COMP CAMS are engineered precision components designed for high-performance Mopar Gen III Hemi engines. These valve locks serve a critical function in your engine's valvetrain, securing the valve stem and preventing unwanted movement during aggressive combustion cycles. Built for enthusiasts and professional engine builders who demand reliability under extreme operating conditions, this set of 16 locks is essential for any serious Hemi platform upgrade or rebuild.

These Super Locks feature a 7-degree design geometry optimized for the 8mm valve stem specification found on Gen III Hemi applications. Manufactured from hardened steel in natural finish, the triple groove design provides superior contact surface area and enhanced retention compared to standard locks. The geometry minimizes stress concentration on the valve stem while maximizing grip strength, allowing your valvetrain to withstand higher spring pressures and sustained RPM loads without valve float or stem damage. This construction ensures consistent performance across extended high-rev operation.

These locks are specifically engineered for Dodge Hemi platforms and compatible with most aftermarket and OEM Hemi cylinder heads using standard 8mm valve stems. Whether you're assembling a stroker motor, upgrading spring rates for increased valve lift, or rebuilding a performance engine, proper valve lock selection is non-negotiable for durability and reliability. The set of 16 provides complete coverage for a typical small-block configuration. Installation pairs seamlessly with corresponding valve spring kits and keepers, making this a cornerstone component in any serious Hemi valvetrain assembly.
