Product Description

The Cometic C5876-051 is a high-performance MLS (Multi-Layer Steel) head gasket engineered specifically for the 6.1 L Gen-3 Hemi V8 platform. Its 0.051" thickness balances strong sealing with optimal deck clearance, making it ideal for both street and performance applications.

With three stainless-steel layers and Viton-coated embossed outer surfaces, this gasket offers excellent durability under high clamp loads and thermal stress. The design helps distribute load evenly, minimizing distortion - especially important in high-output or tuned engines.

Installation is straightforward when head and block surfaces are clean and flat. Thanks to its multi-layer design, no additional sealant or re-torque is required, provided torque specifications are followed. This gasket is especially suitable for engines in the Chrysler 300 SRT8, Dodge Charger / Magnum / Challenger SRT8, and Grand Cherokee SRT8.
