4.100 MLS Head Gasket .051 - Dodge 6.1L

The Cometic Gaskets 4.100 MLS Head Gasket .051 is a multi-layer steel cylinder head gasket engineered specifically for the Dodge 6.1L Mopar Gen III Hemi engine. This component is critical for maintaining proper compression seal and preventing coolant or oil leakage between the cylinder head and engine block—a function that directly impacts engine reliability, power output, and longevity.

The .051-inch compression thickness and 4.100-inch bore specification are calibrated to Hemi Gen III architecture standards. Multi-layer steel construction delivers superior sealing performance over traditional single-layer designs, resisting blow-by and maintaining clamping force across the full range of engine operating temperatures and cylinder pressures. The MLS (Multi-Layer Steel) design excels in high-output and modified applications where stock gaskets may fail, making it a preferred choice for builders and enthusiasts pursuing reliability in demanding engine builds.

This gasket is essential during cylinder head installation, replacement, or rebuild work on Dodge 6.1L Hemi platforms including trucks, SUVs, and performance vehicles. Proper installation requires clean head and block surfaces and correct torque sequence per OEM specifications. Cometic's reputation for precision-engineered gaskets makes this unit a trusted component for engine builders and technicians performing professional-grade assembly and restoration work.

Whether replacing a failed OEM gasket or upgrading during a rebuild, the Cometic MLS head gasket delivers the sealing integrity and durability expected from a premium OEM-equivalent replacement. Each unit is sold individually—ensure accurate part fitment by confirming the 4.100-inch bore and .051-inch thickness match your specific Hemi engine configuration before purchase.
