Cometic MLS Head Gaskets (4.100" Bore)

03-25 Chrysler / Dodge / Ram / Jeep 5.7L Hemi

C5750 / C5749

Cometic MLS Head Gaskets (4.100" bore) are engineered for your vehicle Gen III Hemi engines. Designed with multi-layer steel (MLS) construction, these gaskets provide maximum sealing performance for high-output engines. The embossed outer layers are coated with heat-resistant Viton for superior fluid sealing, while the uncoated stainless steel shim layer can be varied to achieve desired compression ratios. MLS gaskets withstand the shearing forces between aluminum and cast-iron components, resist corrosion, and rebound for long-lasting durability. Available for left-hand (LHS), right-hand (RHS), or as a complete set in multiple thicknesses (.040", .051", .060"), they deliver precise fitment and exceptional reliability for high-performance or everyday use.
