Product Details

The Cometic C15376-062 is a multi-layer steel (MLX) cylinder head gasket engineered specifically for GM 6.6L Duramax diesel engines. This high-performance gasket features a .062" (1.57mm) compressed thickness and a 4.130" bore diameter, designed to provide superior sealing under extreme cylinder pressures and temperatures common in diesel applications.

Key Features:

  • Multi-Layer Steel (MLX) construction for maximum durability and heat resistance
  • .062" compressed thickness provides enhanced sealing for stock and modified applications
  • 4.130" bore diameter optimized for Duramax cylinder dimensions
  • Left-hand side (LHS/driver side) application
  • Compatible with LB7, LLY, LBZ, LMM, LGH, and LML Duramax engine codes (2001-2016)
  • Engineered to withstand high boost and compression loads
  • Precision-manufactured for consistent clamping and sealing performance

Cometic's MLX gaskets utilize multiple layers of stainless steel with advanced coating technology to create a reliable seal that accommodates thermal expansion and engine movement. This gasket is ideal for performance builds, engine rebuilds, or replacing failed OEM gaskets on high-mileage Duramax engines. Sold individually for one cylinder head.
