Supertech Lash Cap 6mm Dia 2.90mm Thick 2.8mm Deep

This product is a single Supertech valve lash cap. It measures 6mm in diameter, is 2.90mm thick, and has a depth of 2.8mm. Lash caps are small components used in engine rebuilding, specifically when working with the valvetrain. They sit between the valve stem and the rocker arm (or camshaft lobe, depending on the engine design) to help set and maintain the correct valve lash, which is the small gap needed for proper valve operation as parts expand with heat.

When rebuilding an engine or performing valvetrain adjustments, selecting the correct lash cap thickness is crucial for achieving the specified valve clearance. This particular cap offers a specific thickness and depth to help fine-tune that clearance. Using the right lash caps ensures your engine's valves open and close at the correct times, contributing to efficient operation and performance.
