• 4.130" bore diameter precisely matched to Duramax cylinder specifications
• Left-hand side (LHS) application for driver-side cylinder bank
• Advanced embossment technology ensures even load distribution
• Viton rubber coating provides enhanced sealing around combustion chambers
• Stainless steel construction resists corrosion and extreme temperatures

Compatible with GM Duramax Engine Codes:

• LB7 (2001-2004)
• LLY (2004.5-2005)

Cometic's MLX gaskets feature multiple layers of stainless steel with strategically placed embossments that allow the gasket to react and seal against the piston motion and extreme cylinder pressures found in high-performance and stock diesel applications. The Viton rubber coating on the outer layers provides the necessary micro-sealing while the stainless steel core layers provide strength and rebound characteristics.

This gasket is ideal for engine rebuilds, head resurfacing projects, or upgrades requiring precise compression control. Cometic gaskets are trusted by professional engine builders and are manufactured in the USA to strict quality standards.
