Supertech Lash Cap 5.5mm Dia 2.5mm Deep 1.90mm Thick

This is a Supertech valve lash cap, measuring 5.5mm in diameter. It's designed to sit on top of the valve stem, providing a hardened surface for the rocker arm or camshaft lobe to act upon. These are commonly used when rebuilding or modifying an engine, especially when using aftermarket camshafts or when valve stem heights need adjustment for proper valvetrain geometry.

This particular lash cap has a thickness of 1.90mm and a depth of 2.5mm. It's made from a durable material to withstand the constant impact and friction from the valvetrain. Ensuring the correct lash cap is used is important for maintaining proper valve lash settings and preventing premature wear on both the valve stem and the valvetrain components.
