Cometic AMC 4.0L Inline 6 .120in MLS Cylinder Head Gasket - 4.000in Bore

If you're rebuilding the top end of your 1987-2001 Jeep Cherokee, Comanche, Grand Cherokee, Wagoneer, or Wrangler, a solid cylinder head gasket is crucial. This Multi-Layer Steel (MLS) head gasket from Cometic is built specifically for the AMC 4.0L inline 6 engine, featuring a 4.000-inch bore and a compressed thickness of .120 inches. It’s designed to handle the demands of high-output engines without needing any additional sealants.

Cometic's MLS gaskets are well-built with multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction makes them suitable for mating aluminum heads to either aluminum or cast iron blocks, as they can manage the shearing forces that occur between different metals. The center layer is stainless steel and can be varied in thickness to meet specific requirements, like the .120-inch dimension on this particular gasket.
