About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with a 3.950-inch bore and a compressed thickness of 0.060 inches, making it a solid choice for your AMC 4.0L inline-6 engine. MLS gaskets are known for their strength and ability to seal effectively, even with different block and head materials like aluminum to cast iron. They don't require any additional sealants, simplifying installation.

The construction features multiple stainless steel layers for increased durability and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a good seal in demanding conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet specific engine requirements, like the 0.060-inch dimension on this particular gasket.

This gasket is a popular option for those rebuilding or repairing the top end of their Jeep Cherokee, Comanche, Grand Cherokee, Wagoneer, or Wrangler from the late 80s through the mid-2000s. Its robust construction is designed to handle the sealing demands of higher output engines.
