Overview:

The Cometic 6.1L Gen-3 Hemi .044 MLX Head Gasket is engineered specifically for high-performance Chrysler Gen-3 Hemi engines found in select Chrysler, Dodge, and Jeep models from 2005 to 2010. Designed to provide a superior seal between the cylinder head and engine block, this gasket is ideal for enthusiasts and professionals seeking reliable durability and enhanced engine integrity under demanding conditions.

Featuring advanced HP shim technology, this head gasket increases clampload around the combustion chamber, improving sealability especially on open deck blocks. It is a direct fit replacement for vehicles equipped with a 4.100" bore, ensuring precise compatibility and ease of installation.

Key Features:

Cometic’s 6.1L Gen-3 Hemi .044 MLX Head Gasket offers a range of benefits designed to enhance engine performance and longevity:

  • HP shim technology increases clampload for improved combustion chamber sealing
  • Specifically engineered for Chrysler 6.1L Gen-3 Hemi engines with a 4.100" bore

Construction & Design:

This head gasket is crafted using Cometic’s proprietary MLS (Multi-Layer Steel) technology, which combines multiple layers of high-grade steel with elastomer coatings to create a robust, flexible seal. The .044" thickness is optimized to maintain proper combustion chamber volume while providing enhanced durability against warping and gasket blowouts.

The inclusion of HP shim technology reinforces the gasket’s sealing surface around the combustion chamber, increasing clamp load and reducing the risk of leaks in high-performance or high-boost applications. This design consideration is especially critical for the open deck architecture of the Gen-3 Hemi engine block.
