C9132 Cometic Cylinder head gaskets 3-7/8" bore .045" MLS for Harley-Davidson

These Cometic Multi-Layer Steel (MLS) cylinder head gaskets are a top-tier choice for Twin Cam builds. Sold as a pair for one complete engine, they feature a 3-7/8 inch bore and a .045 inch thickness, making them perfect for 88 to 95 inch big bore conversions or as a standard replacement for 103 inch OEM Harley-Davidson engines. They are constructed from embossed stainless steel layers coated with a high-temperature polymer rubber, ensuring a reliable seal that eliminates the need for dowel pin o-rings. These gaskets fit 1999 to 2017 Twin Cam models, though they are not compatible with 2014 to 2016 Twin Cooled engines. They serve as a high-performance alternative to OEM 16787-99A, providing excellent torque retention and thermal resistance for demanding street or performance applications.
