Supertech Lash Cap 5.5mm Dia 2.5mm Deep 1.00mm (0.039in) Thick

This Supertech lash cap is a small but important component for fine-tuning your engine's valve lash. It's designed to sit on top of the valve stem, providing a precise surface for the rocker arm or cam follower to act upon. This particular cap has a 5.5mm diameter and a thickness of 1.00mm, which is useful when you need to make very small adjustments to achieve the perfect valve clearance.

When rebuilding an engine or performing valve adjustments, getting the lash just right is key for performance and longevity. Too much lash can lead to noisy operation and reduced power, while too little can cause valves to stay open slightly, leading to burnt valves and poor compression. These Supertech caps are well-built and offer a straightforward way to achieve those critical clearances without needing to machine original parts.
