What is the purpose of these valve lash caps?

These hardened lash caps are designed to protect the tip of your valve stems from the intense pounding they experience in high-RPM racing engines. They help maintain valve train accuracy and prevent damage to the valve stems.

Are these lash caps suitable for all engines?

No, these specific lash caps are designed for 426 Hemi engines with 5/16 inch valve stems. They are precision machined for that application and are particularly beneficial for engines running at high RPMs or with aggressive cam profiles.

Do these lash caps come with any special installation tools?

The manufacturer's description notes that these lash caps fit valve stems well and are easily removed, suggesting they can be installed without specialized tools. However, it's always recommended to consult installation guides for best practices.

Product Details

This product includes a set of 16 hardened valve lash caps from COMP Cams, specifically made for 426 Hemi engines. These caps are designed to fit valve stems with a 5/16 inch diameter. They are precision machined and ground flat to ensure accuracy in your valve train adjustments, which is crucial for maintaining consistent performance, especially in demanding racing applications.

Modern racing engines often operate at higher RPMs with aggressive cam profiles, putting significant stress on the tip of the valve stem. This constant pounding can lead to severe wear. These lash caps are a well-built solution to protect your valve stems from this harsh treatment. They are particularly recommended for use with titanium valves, as they fit the valve stems snugly and are designed for easy removal when needed. The caps have a .190 inch overall head height and a .080 inch thickness, providing a solid barrier.

This set is a popular choice for owners of classic Mopar muscle cars like the Dodge Challenger, Charger, Coronet, and Plymouth Cuda, GTX, and Road Runner from the late 60s and early 70s. Ensuring your valve train components are properly protected is key to reliable performance when pushing your engine hard.
