What is the primary function of a valve lock keeper?

Valve lock keepers, also known as valve locks, work in conjunction with the valve spring retainer to hold the valve spring compressed. This assembly keeps the valve securely in its guide and sealed in the cylinder head when not in operation.

Why is titanium used for these valve lock keepers?

Titanium is chosen for its high strength-to-weight ratio. Using titanium keepers reduces the mass in the valvetrain, which can help improve stability and performance, especially at higher engine speeds.

What does the 'bead lock' design mean?

The bead lock design refers to a specific profile on the keeper that helps it grip more securely inside the valve spring retainer. This feature provides an improved mechanical lock, reducing the chance of the keeper coming loose under stress.

About this part

Product Details

Manley Performance offers these titanium valve lock keepers, part number 13061T-8, designed for engine builds where weight savings and strength are critical. These keepers are a crucial component in the valvetrain, working with the valve spring to keep the valves properly seated. They are specifically designed for a .3415 inch valve stem diameter and feature a bead lock design for added security.

Crafted from titanium, these keepers are notably lighter than steel alternatives, which can help reduce overall valvetrain mass. This reduction in mass can lead to improved valvetrain stability at higher RPMs. The bead lock feature is a practical detail that helps ensure the keeper stays securely in place, even under the stress of aggressive engine operation. They are a well-built choice for performance engine assemblies where precision and reliability are paramount.
