About this part

Product Details

This product is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chrysler LA V8 engines. It features a 4.125-inch bore and a compressed thickness of 0.098 inches, with an uncompressed thickness of 0.075 inches. This gasket is built with multiple layers of stainless steel, with the outer layers coated in Viton rubber. This construction is ideal for sealing aluminum heads to aluminum blocks, or aluminum heads to cast iron blocks, as it can handle the shearing forces between different metals. The Viton coating is heat resistant up to 482 degrees Fahrenheit and meets the demands of harsh sealing environments.

The multi-layer steel design provides increased strength and the ability to rebound, helping to resist corrosion. The center layer is uncoated stainless steel, allowing for variations in thickness to meet different engine requirements. Because these gaskets are well-built with advanced materials, they do not require any additional sealants for installation. This gasket fits a wide range of Chrysler, Dodge, and Plymouth vehicles from the early 1970s through the early 1990s, including models like the Dodge D150 Pickup, Chrysler Newport, and Dodge Charger.
