Overview:

The Cometic MLS Head Gasket is engineered specifically for Dodge Ram 2500 and Ram 3500 diesel engines from 1998 to 2008 featuring round port designs. This multi-layer steel (MLS) gasket delivers superior sealing performance and durability for demanding diesel applications. Designed to withstand high cylinder pressures and thermal cycling, it is an ideal upgrade for those seeking reliable head gasket performance in heavy-duty trucks. Whether you are rebuilding your engine or upgrading for enhanced reliability, this gasket ensures a precise seal between the cylinder head and engine block.

Built to meet the rigorous demands of diesel engines, the Cometic MLS gasket offers excellent resistance to blowouts, corrosion, and bore distortion, making it a trusted choice for both professional mechanics and performance enthusiasts.

Key Features:

This MLS head gasket incorporates advanced materials and design features to provide a durable and effective seal under harsh conditions:

• Constructed from three layers of high-strength stainless steel for enhanced durability and strength.
• Outer layers are embossed and coated with a heat-resistant Viton (fluoroelastomer rubber) material, rated up to 250°C (482°F), to withstand extreme temperatures and harsh sealing environments.
• Center shim layer is uncoated stainless steel, allowing for customizable thickness to meet specific engine requirements.
• Designed to handle the shearing forces between aluminum cylinder heads and cast iron blocks without failure.
• Promotes even torque distribution across the sealing surface, reducing bore distortion and improving engine longevity.
• No re-torque required after installation, simplifying maintenance and reducing downtime.
• Compatible with both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

Construction & Design:

The Cometic MLS Head Gasket features a robust three-layer stainless steel construction that balances strength, flexibility, and corrosion resistance. The outer layers are precision embossed to enhance sealing capability and coated with a Viton-based material that provides exceptional heat resistance and chemical durability. This coating ensures a reliable seal even under the extreme thermal and mechanical stresses typical of diesel engines.

The uncoated stainless steel shim in the center layer allows for precise thickness adjustments, ensuring a perfect fit and optimal compression across the gasket surface. This design minimizes bore distortion and maintains consistent sealing pressure, which is critical for maintaining engine performance and preventing leaks.

Installation & Fitment:

This head gasket is a direct fit replacement for Dodge Ram 2500 and Ram 3500 diesel engines from 1998 through 2008 with round port cylinder heads. Installation requires standard head gasket replacement procedures and does not necessitate any modifications or special re-torqueing steps. The gasket’s design ensures a secure seal immediately upon proper torque application, streamlining the installation process and reducing the risk of future leaks.
