Valve Guide .545 OD/.309 ID/ 2.420 Long

The BRODIX Valve Guide .545 OD/.309 ID/2.5 Long is a precision engine component designed for high-performance marine and automotive applications where reliability under sustained load is crucial. This component is essential for builders and mechanics who are rebuilding heads that demand tight tolerances and consistent valve sealing.

Manufactured to exacting specifications, this valve guide features a .545-inch outer diameter and a .309-inch inner diameter bore, accommodating standard 5/16-inch valve stems. The 2.5-inch length ensures optimal engagement within the cylinder head, providing thermal stability and minimizing lateral valve movement during high-RPM operation. Its cast or ductile iron construction resists wear from repeated stem contact while maintaining dimensional stability across wide temperature ranges.

Engine builders and marine professionals working on BRODIX cylinder head platforms will benefit from this guide's precise OD/ID ratio, which ensures secure press-fit installation without drift or binding. The valve guide's design is particularly advantageous for marine engines, which require components that resist saltwater-induced corrosion and maintain concentricity under the demanding conditions of high-performance operation.
