Cometic C9837 MLS Head Gasket 96mm Bore .043" Twin Cam with Dowel O-Rings

The Cometic C9837 is a premium Multi-Layer Steel (MLS) head gasket designed for 1999 and later Harley-Davidson Twin Cam engines with 96mm (3.78") big bore cylinders. This .043" (1.09mm) thick gasket incorporates advanced dowel pin O-rings to prevent oil seepage at critical locating points, addressing a common concern in high-performance Twin Cam builds.

Key Features:

• Multi-Layer Steel construction with Load Control Embossments (LCE) for even torque distribution
• 96mm bore diameter optimized for big bore Twin Cam applications
• .043" compressed thickness provides proper compression ratio control
• Integrated dowel pin O-rings seal oil return passages and prevent leaks
• Reduces bore distortion and improves piston ring seal for maximum power
• Made in the USA with American-manufactured materials

Cometic MLS gaskets are engineered to handle the extreme cylinder pressures and temperatures of modern high-performance V-Twin engines. The LCE technology distributes clamping force evenly across the sealing surface, while the included dowel O-rings provide additional protection against oil migration at the cylinder-to-head interface.
