What is the purpose of a guide plate?

A guide plate sits between the cylinder head and the rocker arm. Its main job is to keep the pushrod properly aligned, especially in performance engines with higher spring pressures and camshaft lift. This ensures consistent valvetrain geometry and prevents excessive wear.

What size pushrods and studs does this guide plate work with?

This specific COMP Cams guide plate is designed for 3/8 inch diameter pushrods and 7/16 inch rocker studs. It's important to match these sizes to your engine's components for proper fitment and function.

Does this guide plate come with hardware?

This product is for the guide plate only. It does not include any additional hardware such as pushrods, rocker arms, or studs. You will need to source those separately if your build requires them.
