C4548-040

Overview:

The Cometic MLS (Multi-Layer Steel) Head Gasket is engineered specifically for the 2003 to 2005 Dodge Neon SRT-4, featuring an 87.5mm bore and a .040" thickness. Designed to deliver superior sealing performance, this gasket is ideal for high-output engines that demand reliability under extreme conditions. It eliminates the need for additional sealants, providing a clean and efficient installation process.

Perfect for enthusiasts and professionals alike, this head gasket ensures a durable seal between aluminum heads and either aluminum or cast iron blocks, making it a versatile choice for the Neon SRT-4’s turbocharged engine platform.

Key Features:

Cometic’s MLS head gasket incorporates advanced materials and design elements to meet the rigorous demands of performance engines. Key features include:

• Multi-layer stainless steel construction for enhanced strength and durability
• Embossed outer layers coated with Viton, a heat-resistant fluoroelastomer, providing excellent sealing under high temperatures up to 250°C (482°F)
• Corrosion-resistant materials that extend gasket life and maintain integrity
• Designed to withstand the shearing forces between dissimilar metals such as aluminum heads and cast iron blocks
• Center shim layer of uncoated stainless steel customizable for precise thickness requirements
• No sealants required, simplifying installation and reducing potential failure points
• Optimized for high-output, turbocharged engines like the Dodge Neon SRT-4

Construction & Design:

The Cometic MLS head gasket is constructed from multiple layers of high-grade stainless steel, providing a resilient and flexible seal capable of rebounding under thermal cycling and mechanical stress. The outer layers are embossed and coated with Viton, a specialized rubber-based material known for its exceptional heat resistance and chemical durability. This coating ensures a tight seal against combustion gases and coolant leaks, even in harsh operating environments.

The gasket’s center shim layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine build requirements. This multi-layer design effectively manages the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing gasket failure due to metal fatigue or warping.

Installation & Fitment:

This head gasket is a direct fit replacement for the 2003–2005 Dodge Neon SRT-4 with an 87.5mm bore. Installation requires standard head gasket replacement procedures and does not necessitate any modifications to the engine block or cylinder head. The gasket’s design eliminates the need for additional sealants, streamlining the installation process and reducing the risk of leaks.

For best results, ensure proper surface preparation and torque specifications are followed according to manufacturer guidelines.

What's Included:

• One Cometic MLS .040" Head Gasket (87.5mm bore)
