Fitment Notes

• Fits the 6.4L Apache HEMI V8 (392ci) only - this is a gasoline V8 engine; this part has NO application to any diesel engine including the 6.4L Power Stroke or any Cummins engine
• Head Set (HS) designation - contains all gaskets and seals required to remove and replace the cylinder heads; for a complete engine rebuild, combine with the appropriate Mahle lower/conversion gasket set (CS) available separately
• Not intended for race applications - designed for OE-quality street rebuilds and repairs
• Verify fitment by trim level and engine code before ordering - the 6.4L HEMI is exclusive to SRT8, SRT, SRT 392, Scat Pack, and related high-performance trim variants; base and standard V8 models use a different engine (5.7L HEMI)
• Head bolt reuse must be evaluated by your engine builder - Mahle recommends verifying head bolt condition per the OEM service manual for this application before reuse
• Packaged in shrink-wrapped trays allowing visual contents verification before opening

Features

• OE form, fit, and function - engineered to Mahle Original specifications matching the factory head gasket set for the 6.4L HEMI, ensuring correct sealing geometry, bolt hole alignment, and material compatibility with the aluminum cylinder heads and block
• Complete head gasket set - includes all gaskets and seals needed for a cylinder head removal and reinstallation, eliminating the need to source individual components separately
• OE-equivalent or better materials throughout - Mahle utilizes materials selected to meet or exceed the original equipment sealing specifications for each individual gasket and seal in the set
• Multi-layer steel (MLS) head gaskets provide superior combustion sealing, resistance to blow-out, and durability under the high cylinder pressures and temperatures of the 6.4L HEMI
• Shrink-wrapped tray packaging allows visual verification of all contents before opening, ensuring the correct set is in hand prior to beginning engine disassembly
• Mahle Original - produced by the world's largest OE gasket supplier, with the same quality standards applied to factory new vehicle production

Product Description

The Mahle HS55457 is a complete OE-grade head gasket set for the 6.4L Apache HEMI V8 (392ci) as fitted to Dodge Challenger, Charger, Durango SRT, Chrysler 300 SRT8, and Jeep Grand Cherokee SRT/SRT8 models from 2011 through 2020. The "HS" designation identifies this as a Head Set - a comprehensive collection of all gaskets and seals required to remove and reinstall the cylinder heads, including the critical head gaskets themselves, intake and exhaust manifold gaskets, valve cover gaskets, valve stem seals, fuel injector O-rings, throttle body gasket, thermostat gasket, and additional ancillary seals. For a complete engine rebuild covering lower-end sealing as well, this set must be paired with the appropriate Mahle lower/conversion gasket set (CS), available separately.

Mahle Original head gasket sets are built to OE form, fit, and function - the same quality and dimensional standards that Mahle supplies to vehicle manufacturers worldwide. Materials across the set are selected to meet or exceed the original equipment specifications for each individual component, with multi-layer steel (MLS) construction for the cylinder head gaskets providing robust combustion sealing and long-term durability under the high cylinder pressures of the naturally aspirated 485 hp 6.4L HEMI. The set is packaged in shrink-wrapped trays, allowing full visual inspection of the contents before opening - a practical benefit when confirming parts on the workbench before committing to engine disassembly.

WARNING: This part is for the 6.4L HEMI gasoline V8 only - it has no application to any diesel engine. Some third-party retailers incorrectly list this part number under Cummins or Power Stroke diesel applications; these are data entry errors. This set fits only the 6.4L Apache HEMI V8 (392ci) found in SRT8, SRT, SRT 392, Scat Pack, and related performance trims. Not intended for race use. Verify your specific trim and engine code before ordering.
