The Cometic C15203-060 is a precision-engineered Multi-Layer Steel (MLX) cylinder head gasket designed specifically for GM LT1 and LT4 Generation 5 small block V8 engines. This gasket features a 4.150-inch bore diameter and .060-inch compressed thickness, providing superior sealing performance for high-performance and stock applications.

Key Features:

• Multi-Layer Steel (MLX) construction for maximum durability and reliable sealing
• 4.150-inch bore diameter optimized for LT1/LT4 engine specifications
• .060-inch compressed thickness for precise deck height control
• Designed for GM Gen-5 LT1 and LT4 small block V8 engines
• Handles high cylinder pressures and extreme temperatures
• Embossed stainless steel layers with a Viton rubber coating for superior conformability

Cometic's MLX gaskets feature multiple layers of stainless steel with strategically placed elastomer coatings, creating a gasket that conforms to irregular surfaces while maintaining excellent recovery properties. This design ensures consistent clamping pressure across the entire sealing surface, preventing head gasket failure even under demanding conditions. Ideal for stock rebuilds, performance upgrades, and forced induction applications on modern GM LT-series engines.
