Supertech Lash Cap 6mm Dia 4.55mm Thick 2.8mm Deep

This product is a single Supertech valve lash cap. It measures 6mm in diameter, is 4.55mm thick, and has a depth of 2.8mm. These caps are used in engine valve train assemblies to fine-tune valve lash, which is the small gap between the valve stem and the rocker arm or camshaft lobe. Proper valve lash is crucial for engine performance and longevity, ensuring valves open and close at the correct times and that components don't make metal-on-metal contact.

When rebuilding or modifying an engine, especially one where the camshaft profile has been changed or the valve train components have been resurfaced, the valve lash may need adjustment. These lash caps sit on top of the valve stem and provide a surface for the camshaft or rocker arm to act upon. By selecting the correct thickness and depth of lash cap, you can achieve the precise valve clearance specified by the manufacturer or desired for a performance build. This particular cap is well-made and designed to fit standard 6mm valve stems.
