The Cometic C15715-054 MLX Cylinder Head Gasket is specifically engineered for DART Gen 3 Hemi aftermarket engine blocks. This left-hand gasket features a 4.150-inch bore diameter and .054-inch thickness for precise fitment in high-performance Gen 3 Hemi applications.

MLX Stopper Technology:

The advanced MLX design incorporates active combustion and water/oil seals on the outer layers, along with a .006-inch thick fold-over "Stopper" layer that limits compression and enhances seal durability. This unique construction includes a .060-inch cross-section that increases stress resistance around the combustion chamber, making it ideal for demanding high-performance and racing applications.

Key Features:

• Multi-Layer Xtreme (MLX) construction with stopper layer technology
