Gen-3 Hemi LH MLS Head Gasket 3.996 Bore .035

The Gen-3 Hemi LH MLS Head Gasket 3.996 Bore .035 is a critical sealing component engineered for Mopar's legendary third-generation Hemi engine platform. Built by MAHLE ORIGINAL/CLEVITE—industry leaders in OEM gasket manufacturing—this multi-layer steel (MLS) gasket is essential for builders, engine rebuilders, and performance enthusiasts restoring or upgrading Gen-3 Hemi powerplants. Whether you're completing a factory rebuild or preparing a stroker combination, proper head gasket selection directly impacts compression sealing, coolant integrity, and long-term engine reliability.

This gasket features a 3.996-inch bore diameter and 0.035-inch thickness, precisely calibrated to work with Gen-3 Hemi cylinder head and block surfaces. The MLS construction uses stainless steel facings bonded to a spring-steel core, creating a gasket that resists blowby, accommodates thermal cycling, and maintains a consistent seal under high combustion pressures typical of modern Hemi builds. The left-hand (LH) configuration ensures proper alignment on the driver's side of the engine, critical for achieving proper clamping load distribution when torqued to spec. This OEM-quality gasket is compatible with both stock and modified Hemi applications, from 5.7L displacement up through larger stroker engines.

Engine builders and Mopar performance shops specify MAHLE gaskets for repeatability and durability—this LH unit is ideal for any Dodge, Chrysler, or Jeep platform running a Gen-3 Hemi. Whether you're rebuilding a truck engine, street-performance application, or off-road build, proper head gasket installation requires clean deck surfaces, correct fastener torque sequencing, and quality gasket material. At 0.995 pounds and compact in profile, the Gen-3 Hemi LH MLS Head Gasket delivers OEM reliability with the precision fit that separates professional engine work from amateur results.
