Product Details

The Cometic C9721-045 is a premium Multi-Layer Steel (MLS) head gasket kit designed for Harley-Davidson Twin Cam engines. Featuring a 3.875-inch bore diameter and .045-inch compressed thickness, this gasket provides superior sealing performance for high-performance and heavy-duty applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum durability and heat resistance
  • 3.875-inch bore diameter optimized for Twin Cam cylinder heads
  • .045-inch compressed thickness for precise compression ratio tuning
  • Complete head gasket kit with all necessary gaskets for installation
  • Engineered to handle extreme cylinder pressures in modified engines
  • Eliminates gasket failure common with stock composite gaskets

Cometic MLS head gaskets feature multiple layers of stainless steel with integrated elastomer coatings that micro-seal surface imperfections while withstanding extreme temperatures and pressures. This gasket is ideal for performance builds, increased compression applications, and engines running forced induction or nitrous oxide systems.
