What is the purpose of a valve spring retainer?

A valve spring retainer holds the valve spring in place at the top of the valve stem. It works with the valve spring to control valve movement and prevent valve float, especially at higher engine speeds.

What material is this retainer made from?

This retainer is precision machined from high-grade SAE 4140 chromemoly steel. It also features a black oxide finish for added protection.

Does this retainer come with valve locks or keepers?

This product listing is for the steel retainer only. Valve locks, also known as keepers, are typically sold separately and are required to secure the retainer to the valve stem.
