Mopar Left Side Cylinder Head Gasket | Gen 3 HEMI OEM Replacement (5038281AE)

The Mopar Left Side Cylinder Head Gasket is a genuine OEM replacement engineered to create a precise seal between the engine block and the driver’s side cylinder head on Gen 3 HEMI engines. Whether you’re completing a factory engine repair, rebuilding a high-mileage HEMI, or assembling a high-performance engine with aftermarket components, using a genuine Mopar head gasket ensures the fitment, durability, and sealing performance originally designed by Chrysler. Proper cylinder head sealing is essential for maintaining compression, preventing coolant and oil leaks, and ensuring reliable engine operation under both everyday driving and extreme performance conditions.

Cylinder head gaskets operate in one of the harshest environments within an engine. They must contain combustion pressures while simultaneously sealing coolant passages and oil galleries through thousands of heat cycles and constant thermal expansion. The Mopar Left Side Cylinder Head Gasket utilizes a durable multi-layer steel (MLS) construction designed to withstand these demanding conditions while maintaining a reliable seal throughout the engine’s service life. Whether installed on a naturally aspirated 5.7L or 6.4L HEMI or a supercharged Hellcat engine, this OEM gasket provides the confidence needed for long-term reliability.

For performance enthusiasts building Gen 3 HEMI engines, quality sealing components are just as important as premium internal engine parts. This head gasket is an excellent choice when installing performance camshafts, CNC-ported cylinder heads, upgraded valve springs, forged rotating assemblies, or boosted combinations. Replacing the head gasket any time the cylinder heads are removed helps eliminate the risk of future sealing issues while protecting the significant investment made in engine upgrades. Combined with properly torqued new cylinder head bolts or head studs, this gasket helps create a durable seal capable of supporting increased cylinder pressures found in naturally aspirated, supercharged, and turbocharged applications.

Unlike many aftermarket alternatives, genuine Mopar gaskets are manufactured to strict factory tolerances for proper alignment of combustion chambers, coolant jackets, and oil passages. This precise engineering helps simplify installation while maintaining factory-level reliability and sealing performance. Professional engine builders and experienced DIY enthusiasts continue to rely on OEM components because they consistently deliver dependable results in both stock replacement and high-horsepower performance applications.

Whether you’re refreshing an aging engine, repairing a failed head gasket, or assembling a complete Gen 3 HEMI for street, drag racing, or roll racing use, the Mopar Left Side Cylinder Head Gasket provides the quality and reliability required for a successful build. At Dusterhoff Racing, we recommend OEM sealing components whenever possible to help ensure long-lasting engine performance.
