Ferrea Nissan 350Z 5.5mm Single Radial Groove Steel Valve Lock - Set of 12

These Ferrea valve locks feature a 5.5mm single radial groove design, a specific choice that helps them seat securely and reliably within the valve stem. They are made from steel, a strong material chosen for its durability in the high-stress environment of an engine's valvetrain. This set includes 12 pieces, enough for a typical 6-cylinder engine like the one found in a Nissan 350Z, ensuring you have what you need for a complete valve job.

When you're rebuilding the top end of your engine, the small parts matter just as much as the big ones. These Ferrea valve locks are designed to hold the valve springs and retainers in place, keeping your valves operating in sync with the camshaft. The steel construction offers good resistance to wear and deformation, which is crucial for maintaining proper valve timing and sealing over time. They fit right into the factory-style valve stem configuration, making them a straightforward replacement part for your 350Z engine build.
