Cometic C5505-052 GM LS Gen-3/4 Small Block V8 MLS Cylinder Head Gasket

The Cometic C5505-052 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for GM LS Gen-3 and Gen-4 small block V8 engines. This gasket features a compressed thickness of .052 inches and a 4.040-inch bore diameter, making it ideal for street performance and modified LS engines requiring precise sealing and compression control.

Key Features:

• Multi-Layer Steel (MLS) construction with multiple layers of stainless steel for superior sealing
• 4.040-inch bore diameter accommodates standard and slightly overbored LS engines
• .052-inch compressed thickness allows for precise compression ratio tuning
• Advanced coating technology ensures optimal sealing under extreme temperatures and pressures
• Eliminates the need for additional sealants when installed properly
• Compatible with LS1, LS2, LS3, LS6, LQ4, LQ9, L92, and other Gen-3/Gen-4 LS V8 engines
• Designed to handle high-performance applications including forced induction

Cometic gaskets are manufactured using precision CNC machining and proprietary materials to ensure consistent quality and reliability. The MLS design allows the gasket to recover and maintain sealing integrity through repeated heat cycles, making it an excellent choice for performance builds, engine rebuilds, and racing applications.
