Product Description

The Cometic C5876-040 is a premium multi-layer steel (MLS) cylinder head gasket made for the Gen III 6.1L HEMI V8 engine (ESF). With a bore of 4.100 inches and compressed operating thickness of .040 inches, it delivers factory-matching compression and reliable sealing even under high output or heavy load. Its outer MLS layers are embossed and Viton-coated to resist thermal and chemical stress, and its stainless-steel core resists bore distortion and corrosion over time.

This gasket fits a wide range of 2005-2010 "SRT8" models, including the **Chrysler 300 SRT8**, **Dodge Charger SRT8**, **Dodge Magnum SRT8**, **Dodge Challenger SRT8**, and **Jeep Grand Cherokee SRT8**, when equipped with the 6.1L HEMI. Be sure to verify that your vehicle has the Gen III 6.1L engine (ESF), since other HEMI variants (such as 5.7L or 6.4L) have different bore or head specifications. Fitment through 2010 confirmed; 2025 unconfirmed.
