About this part

Product Details

If you're rebuilding the top end of your Jeep Cherokee, Comanche, Grand Cherokee, Wagoneer, or Wrangler, a quality head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of the AMC 4.0L inline-6 engine, ensuring reliable performance after your rebuild.

Cometic uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This construction means the gasket requires no additional sealants and is designed to work well with both aluminum and cast iron engine blocks, preventing issues caused by the shearing forces between different metals. The center layer is stainless steel and can be varied in thickness to meet specific requirements; this particular gasket has a bore of 4.000 inches and a compressed thickness of .049 inches.
