Supertech Lash Cap 6mm Dia 4.65mm Thick 2.8mm Deep

This is a Supertech valve lash cap, measuring 6mm in diameter, 4.65mm thick, and 2.8mm deep. It's a small but important piece used in engine valve train assemblies. When rebuilding or modifying an engine, especially one where you're changing camshafts or valve springs, these caps sit on the end of the valve stem. They provide a hardened surface for the camshaft lobe or rocker arm to act against, helping to prevent wear on the valve stem itself.

Supertech makes these lash caps from durable materials to withstand the constant impact and friction they experience. They are designed to fit precisely onto the valve stem, ensuring proper valve train geometry and function. Using the correct size lash cap is crucial for maintaining the intended lash (the small gap) in your valve train, which affects engine performance and longevity. If you're working on a performance build or a full engine overhaul, ensuring you have the right components like these lash caps is key to a reliable result.
