Cometic Chrysler 6.4L Apache Gen-3 Hemi .030in MLS Cylinder Head Gasket - 4.120in Bore - LHS

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's designed for Chrysler's 6.4L Apache Gen-3 Hemi engines, specifically built to handle the demands of high-output applications. This gasket features a 4.120-inch bore and is 0.030 inches undersize, with a compressed operating thickness of 0.036 inches, making it suitable for a range of engine builds and modifications.

The construction uses multiple layers of stainless steel for increased strength and rebound resistance, which helps prevent corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit (250 C). This makes it ideal for sealing between aluminum heads and either aluminum or cast iron blocks, as it can manage the shearing forces that occur between different metals. The center layer is uncoated stainless steel, allowing for varied thickness requirements in engine builds.

This gasket fits a variety of popular vehicles, including the Dodge Challenger, Charger, and Jeep Grand Cherokee, among others. Because it's an MLS gasket, it doesn't require any additional sealants, simplifying the installation process when you're rebuilding your top end.
