What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks, are small components that fit into grooves on the valve stem. They work with the valve spring retainer to hold the valve in place within the cylinder head, ensuring it seats properly.

What does the '+.050 BEAD' designation mean?

This designation indicates that these keepers are manufactured to be 0.050 inches larger than a standard size, and they feature a bead. This sizing and bead design help them to seat more securely in the retainer and prevent them from coming loose.

Are these keepers suitable for high-performance engines?

Manley Performance is a popular brand for performance engine parts. These keepers are well-built and designed for secure seating, making them a solid option for many engine builds, including those with performance modifications.
