What is the primary benefit of using titanium valve locks?

Titanium valve locks are significantly lighter than traditional steel keepers. This reduced mass in the valve train can help improve valve control at higher engine speeds (RPMs).

What does the sizing .3415 -.050 mean for these valve locks?

The .3415 measurement refers to the nominal diameter of the lock. The -.050 indicates that these locks are undersize by 0.050 inches, meaning they are intended for valve stems that have been machined to this specific dimension.

Are these valve locks sold individually or as a set?

This part number includes a set of 16 valve locks, which is typically enough for a complete V8 engine's valve train.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these LOC-TI S7 valve locks are a prime example. If you're rebuilding or modifying an engine where every ounce of weight savings and reliability matters, these keepers are designed to handle the stress. They are made from titanium, which is significantly lighter than steel, helping to reduce valve train mass. This can lead to improved valve control at higher RPMs, which is crucial for performance builds.

These particular locks are sized at .3415 inches and are .050 inches undersize, meaning they are intended for use with valve stems that have been machined down to match. The titanium construction not only saves weight but also offers good strength and resistance to wear under the demanding conditions found in a high-performance engine. They are a well-built component that contributes to the overall integrity and performance of your valve train.
