Cometic C9993-030-020 Revolution Head and Base Gasket Kit for Buell 3.875" Bore

The Cometic C9993-030-020 Revolution Head and Base Gasket Kit is engineered specifically for Buell motorcycles with a 3.875" bore diameter. This comprehensive gasket kit provides everything needed for a top-end rebuild with precision-engineered sealing components designed to handle the demanding conditions of high-performance V-Twin engines.

Kit Specifications:

• 3.875" (98.425mm) cylinder bore diameter
• .030" thick MLS (Multi-Layer Steel) head gaskets
• .020" thick rocker cover gaskets
• Includes all necessary gaskets, seals, and o-rings for complete top-end assembly

Advanced MLS Technology:

• Multi-layer stainless steel construction with embossed layers for superior sealing
• Viton rubber coating on outer layers for extreme temperature and chemical resistance
• Load Control Embossments (LCE) provide even torque distribution across sealing surfaces
• Reduces bore distortion for improved piston ring seal and increased power
• Designed to handle higher cylinder pressures and clamp loads

Cometic gaskets are manufactured in the USA using domestically-sourced materials and represent the latest in gasket technology for powersports applications. The MLS design features an uncoated stainless steel center shim layer that can accommodate various compression requirements, while the embossed and coated outer layers meet the demands of harsh sealing environments found in modern air-cooled V-Twin engines.

This Revolution series gasket kit is ideal for engine builders looking to maintain or increase compression ratios during top-end rebuilds, offering superior sealing performance compared to traditional composite gaskets.
