Supertech Lash Cap 5.5mm Dia 2.8mm Deep 1.32mm (.052in) Thick

If you're rebuilding the top end of your engine, especially if you're working with an adjustable valvetrain or need to fine-tune your valve lash, these Supertech lash caps are a solid choice. They sit between the valve stem and the rocker arm (or camshaft lobe, depending on your engine design) to provide a wear surface and allow for precise adjustment of the valve clearance. This particular cap has a 5.5mm diameter and is 2.8mm deep, with a thickness of 1.32mm, designed to fit specific valve stems.

Made from durable steel, these caps are built to withstand the constant impact and friction they experience during engine operation. Using a lash cap is a common practice when valve stem lengths need to be effectively increased without replacing the valve itself, often seen in performance builds or when using aftermarket camshafts that alter valve lift or duration. Ensuring you have the correct size cap is crucial for proper valvetrain geometry and consistent engine performance.
