Cometic C9721-030 MLS Cylinder Head Gasket Set 3.875" Bore .030" Twin Cam

The Cometic C9721-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket set designed for Harley-Davidson 95/103 cubic inch Twin Cam engines with a 3.875-inch bore and .030-inch compressed thickness.

Advanced MLS Construction:

• Outer layers are embossed and coated on both sides with Viton rubber material designed for harsh sealing environments, with the center shim layer made from uncoated stainless steel that can be varied to accommodate thickness requirements
• Features load-controlled embossments that help conform load distribution across the sealing area, creating an exceptional seal by requiring less clamp load and resulting in less bore distortion
• Stainless steel construction provides increased strength, excellent rebound characteristics, and superior corrosion resistance
• Each gasket is coated with .001-inch thick Viton rubber bonded to the outer stainless steel layers

Key Specifications:

• Bore Size: 3.875 inches
• Compressed Thickness: .030 inches
• Material: Multi-Layer Stainless Steel with Viton coating
• Number of Layers: 3

These MLS head gaskets promote even torque load across the gasket sealing surface utilizing Load Control Embossments (LCE), providing less bore distortion and better piston ring seal for increased power. MLS head gaskets install dry without additional sealant as they are pre-coated with Viton rubber. Made in the U.S.A.
