What does '+.050 inch over size' mean for these valve keepers?

This means the keepers are designed to fit valve stems that have been machined to be 0.050 inches larger than their original stock diameter. It's important to ensure your valve stems match this specification for proper fitment.

Why are these valve keepers made of titanium?

Titanium is used because it's a strong material that can withstand the high temperatures and stresses within an engine's valvetrain. It also offers a weight savings compared to steel, which can contribute to improved valvetrain dynamics.

What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve collets, are small components that fit into a groove on the valve stem. They work with the valve spring retainer to hold the valve spring assembly securely in place, ensuring the valve operates correctly.
