Product Details

The Cometic C5445-120 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler Gen-2 Hemi engines. This precision gasket features a 4.250-inch bore diameter and .120-inch compressed thickness, making it ideal for performance builds requiring superior sealing and durability.

Key Features:

  • Multi-Layer Steel (MLS) construction provides exceptional strength and superior combustion sealing
  • 4.250-inch bore diameter accommodates stock and performance applications
  • .120-inch (3.05mm) compressed thickness allows for custom compression ratio tuning
  • Designed specifically for Chrysler Gen-2 Hemi engines (5.7L, 6.1L, 6.4L applications)
  • Embossed stainless steel layers with Viton rubber sealing beads resist extreme temperatures and pressures
  • Allows for more efficient heat transfer compared to composite gaskets
  • Requires proper surface preparation and flatness for optimal sealing

Cometic MLS gaskets are the preferred choice for high-performance and racing applications where extreme cylinder pressures, thermal cycling, and engine movement demand the ultimate in head gasket technology. The .120-inch thickness makes this gasket suitable for turbocharged, supercharged, and high-compression naturally aspirated Hemi builds.
