Motorsports Valve Seals

The Michigan Motorsports H7100 is a complete kit of 16 hat-style valve seals, specifically designed for use with beehive valve springs in GM LS and LT engines. These hat-style valve seals offer broad compatibility, fitting a wide range of modern LS and LT platforms manufactured between 2001 and 2021. They are suitable for engines utilizing both cathedral and rectangle-port heads, making them ideal for performance builds and truck applications. The seals are tailored for precise fitment with factory-style powdered-metal guides, securing valve stem location without requiring modifications or adapters. It is always recommended to replace valve seals when changing valve springs to prevent oil leaks, smoking, and oil consumption, which is particularly critical for performance-oriented engine builds. This kit provides a full set of 16 seals, sufficient for all intake and exhaust valves on a V8 engine, making it a comprehensive solution for upgrades or complete top-end rebuilds.
