Supertech Lash Cap 6mm Dia 3.6mm Thick 2.8mm Deep.

Supertech is known for making well-built valvetrain components. This specific part is a valve lash cap, designed to sit between the valve stem and the rocker arm or cam lobe. It's a small but important piece that helps maintain proper valve lash adjustment and reduces wear on the valve tip and the rocker arm surface. This particular cap measures 6mm in diameter, is 3.6mm thick, and has a depth of 2.8mm, making it suitable for specific engine builds where precise valvetrain geometry is critical.

Using a lash cap like this one can be a smart move when rebuilding or modifying an engine, especially if you're using aftermarket camshafts or valves that might have slightly different dimensions than stock. It ensures that the contact point is solid and that the rocker arm pivots correctly, which is essential for consistent engine performance and longevity. It's a simple part, but getting the dimensions right is key for proper function.
