Oil Pan Gasket 16-21 Hemi 5.7L

The Oil Pan Gasket 16-21 Hemi 5.7L is a factory-engineered one-piece rubber seal designed specifically for Mopar Gen III Hemi engines. As an experienced mechanic, you know that oil pan gaskets endure constant thermal cycling, pressure fluctuations, and vibration—making them one of the most critical maintenance items on any performance or street engine. The MAHLE ORIGINAL/CLEVITE engineering behind this gasket ensures reliable sealing between the oil pan and engine block, preventing costly oil leaks that can lead to engine damage or environmental contamination.

This one-piece design eliminates the weak points found in multi-piece gaskets, providing superior compression set resistance and durability across repeated heat cycles typical of Hemi performance builds. The rubber compound is formulated to maintain elasticity in the high-temperature environment of a modern V8 engine bay, resisting hardening and shrinkage that causes premature leaks. MAHLE's precision manufacturing ensures exact dimensional tolerances that match OEM specifications, guaranteeing a tight seal without over-compression that can warp the pan or block surfaces.

Whether you're rebuilding a stock 5.7L Hemi, upgrading a tuned engine, or restoring a truck or muscle car powered by this legendary platform, this gasket is essential preventive maintenance. Installation is straightforward during engine-out service or accessible pan-drop procedures common on 2016–2021 chassis, making it an ideal choice for DIY builders and professional shops alike. Using OEM-equivalent gasket material ensures your investment in engine modifications or restoration is protected from the ground up.
