Oil Pan Gasket 11-16 Hemi 5.7L

The Oil Pan Gasket 11-16 Hemi 5.7L is an essential maintenance component for anyone serious about preserving their third-generation Hemi engine's reliability and longevity. Whether you're rebuilding a performance 5.7L, addressing an oil leak on your daily-driver truck or Jeep, or completing routine service work, this OEM-specification gasket seals the critical interface between the oil pan and engine block. Proper oil pan sealing prevents costly leaks that can compromise lubrication flow and contaminate underbody components—a concern that grows with age and mileage on any gen III Hemi platform.

Manufactured by MAHLE ORIGINAL/CLEVITE under part number OS32400, this one-piece rubber gasket is engineered to withstand the thermal cycling and pressurization cycles that occur in high-performance and stock Hemi applications alike. The 0.25-inch thickness provides optimal compression and sealing surface contact while accommodating the precise geometry of gen III Hemi oil pan flanges. Rubber composition resists oil degradation, thermal stress, and vibration better than cork alternatives, delivering a durable seal that outperforms aftermarket compressed-fiber options. The gasket's design ensures even load distribution across the pan mounting surface, critical for eliminating micro-leaks that plague aged or overtightened installations.

This gasket is compatible with 2011–2016 Hemi 5.7L engines found in Ram trucks, Jeep Grand Cherokees, Dodge Chargers, and other Mopar gen III Hemi platforms. Professional technicians and experienced DIY builders trust MAHLE gaskets for their precise tolerances and consistency. During installation, hand-tighten oil pan fasteners in a star pattern to avoid uneven compression or gasket extrusion. Pair this replacement with fresh oil, a new drain plug washer, and proper torque specification per your service manual for a complete, leak-free oil pan service that protects your engine investment.
