Ferrea 3/8 +.050 Steel 10 Deg Valve Locks - Set of 16

This set includes 16 Ferrea valve locks, each measuring 3/8 inch with a 0.050 inch undersize and a 10-degree taper. These are essential components for securing your valve springs to the valve stem, ensuring proper valve train operation in your engine build. Ferrea is known for making well-built engine components, and these valve locks are no exception. They are made from steel for durability and are designed to hold up under the stresses of engine operation.

When rebuilding or modifying an engine, the details matter. These valve locks are a specific size, noted by the +.050, which indicates they are 0.050 inch undersize. This sizing is important for ensuring a precise fit with compatible valve stems, especially when dealing with engines that have had their valve guides or stems machined. The 10-degree angle is also a critical specification that must match the angle of your valve keepers and valve spring retainers for a secure and effective lock.
