Supertech Lash Cap 5.5mm Dia 2.8mm Deep 1.27mm (.050in) Thick

If you're rebuilding the top end of your engine, especially if you're working with performance camshafts or modifying valve lift, you'll need to ensure your valve lash is set correctly. This lash cap from Supertech is designed to sit between the valve stem and the rocker arm (or cam lobe, depending on your engine's design), providing a precise point of contact for adjustment. It's made with durable materials to withstand the constant impact and heat within the valve train.

This particular cap measures 5.5mm in diameter and is 2.8mm deep, with a thickness of 1.27mm (or .050 inches). This specific sizing is important for achieving the correct valve clearance, which directly impacts engine performance, efficiency, and longevity. Using the right lash cap ensures consistent contact and prevents premature wear on your valve train components.
