Product Details

The Cometic C5446-027 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler Gen-2 Hemi engines. This precision-manufactured gasket features a 4.375-inch bore diameter and a compressed thickness of .027 inches, providing optimal sealing performance for both stock and modified applications.

Key Features:

  • Multi-Layer Steel construction for superior durability and heat resistance
  • 4.375-inch bore diameter designed for Gen-2 Hemi engines
  • .027-inch compressed thickness for precise compression control
  • Engineered to handle high combustion pressures and temperatures
  • Resists gasket failure from extreme cylinder pressures
  • Requires proper surface preparation for optimal sealing

Cometic MLS gaskets are constructed from multiple layers of stainless steel, with each layer serving a specific function to maximize sealing performance. The outer layers are embossed to seal minor surface imperfections, while the inner layers provide structural support. This design allows the gasket to maintain a superior seal under extreme conditions, making it ideal for high-performance and racing applications.

Application: Chrysler Gen-2 Hemi engines (5.7L, 6.1L, 6.4L variants)

Important: MLS gaskets require smooth cylinder head and block surfaces (typically 50 RA or smoother) for proper sealing. Surface preparation is critical for installation success.
