Description

The Cometic C9239 is a pair of cylinder head gaskets designed for street riding. These gaskets feature a Multi-Layer Steel (MLS) construction with uncoated stainless steel center layers that can be varied for thickness requirements. The outer layers are embossed and coated with Viton to withstand harsh sealing environments and load conditions. Made in the U.S.A., they promote even torque load and reduce bore distortion for improved piston ring seal.
