What is the purpose of valve lash caps?

Valve lash caps sit on top of the valve stem, providing a hardened surface for the rocker arm to push against. This helps to reduce wear on both the valve stem and the rocker arm, and ensures consistent valve lash adjustment.

What size valve stems do these caps fit?

These Manley wear caps are specifically designed for valve stems that measure 0.3130 inches, which is equivalent to 8mm.

How many wear caps are included in this set?

This set comes with eight wear caps, which is enough for a typical 8-cylinder engine application.
