Supertech Lash Cap 5.5mm Dia 2.5-3mm Deep 1.25mm (0.049in) Thick

If you're rebuilding the top end of your engine, especially if you're working with a camshaft that has a different lobe profile or lift than stock, you'll need to ensure your valve train geometry is correct. These Supertech lash caps are designed to sit on top of your valve stems, providing a precise surface for your rocker arms or cam followers to act upon. This particular cap measures 5.5mm in diameter and is 1.25mm thick, with a depth of 2.5-3mm, intended to help you achieve the correct valve lash adjustment.

Made from durable steel, these caps are built to withstand the constant impact and heat generated within the engine's valve train. Using the correct lash cap thickness is crucial for setting accurate valve lash, which directly impacts engine performance, idle quality, and the longevity of your valve train components. Getting this measurement right ensures that your valves open and close at the optimal time and for the optimal duration.
