Supertech Lash Cap 6mm Dia 2.85mm Thick 2.8mm Deep

This is a Supertech valve lash cap, measuring 6mm in diameter with a thickness of 2.85mm and a depth of 2.8mm. These small but critical components sit between the valve stem and the rocker arm or camshaft lobe, depending on your engine's design. Their primary job is to provide a wear surface and allow for precise adjustment of valve lash, which is the small gap in the valve train that ensures proper sealing and prevents components from colliding.

When rebuilding or modifying an engine, especially one where you're aiming for specific performance characteristics or dealing with different camshaft profiles, lash caps are essential. They help maintain the correct valve clearance, which is crucial for engine health and performance. Using a well-made lash cap like this one from Supertech ensures a consistent and durable contact point in your valve train, helping to prevent premature wear on more expensive components like the camshaft or rocker arms.
