Best Mopar Gaskets in 2026

You are halfway through a weekend oil change on your Jeep when you notice the old metal gasket is flattened and leaking. Swapping in one of these AUTOMAJOR rubber seals is a total game-changer compared to the standard aluminum or plastic alternatives. These 14mm washers are designed to sit snug and flush against the drain plug, providing a much tighter seal that actually holds up over time. Because they are made from high-grade rubber, they offer superior sealing capabilities that prevent those annoying slow drips. With a 15-piece set in the box, you have plenty of spares for future maintenance on your Chrysler, Dodge, or Ram vehicles, making this a reliable staple for any DIY mechanic's toolbox.

Remflex offers a definitive solution for Mopar owners struggling with exhaust leaks caused by warped flanges. These gaskets solve the common headache of dissimilar material expansion between aluminum heads and steel manifolds by utilizing 100 percent flexible graphite. Unlike traditional composite gaskets that harden or shrink over time, these stay resilient because they lack rubber binders. The 1/8 inch thickness is specifically engineered to crush by 50 percent, allowing the material to flow into pits and gaps up to 1/16 inch deep. This compressibility ensures a permanent seal that eliminates the frustrating cycle of constantly retightening flange bolts. If your exhaust system is leaking due to thermal contraction and expansion, this two-piece set provides the heavy-duty sealing capability required for a reliable repair.

Most mechanics will tell you that a perfectly flat flange is the only way to prevent an exhaust leak, but Remflex challenges that entire philosophy. These gaskets use a specialized flexible graphite material that has been a staple in the performance community for over three decades. Instead of struggling to resurface old, pitted metal, you can rely on the 1/8 inch thickness to do the heavy lifting. The design allows the material to crush by 50 percent, meaning it effectively fills any gaps or surface imperfections up to 1/16 inch. This makes them an incredible solution for Mopar Hemi 370 or 6.1L engines with D-shaped ports. It turns a potentially frustrating resurfacing job into a straightforward installation that actually holds a seal.

After weeks of driving through extreme temperature shifts, I finally realized why my exhaust setup kept leaking. The mismatch between aluminum cylinder heads and steel manifolds is a nightmare for sealing, but these Remflex gaskets actually solve the warping issue. Because they are made of 100 percent flexible graphite with no rubber binders or composites, they don't shrink or harden over time. The standard 1/8 inch thickness is designed to crush by 50 percent, which allows the material to flow into pits or gaps up to 1/16 inch deep. It effectively creates a permanent seal that stays put even as the metal expands and contracts, meaning you can finally stop constantly retightening your flange bolts.

The ORAEVY Intake Manifold Gasket Set offers an incredibly comprehensive solution for anyone tackling vacuum leaks or engine maintenance on a Pentastar engine.
