About this part

Product Details

If you're rebuilding the top end of your 1987-2001 Jeep Cherokee, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of the AMC 4.0L inline-6 engine.

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 high temperatures and harsh sealing environments, making it suitable for both aluminum and cast iron blocks. This gasket has a compressed thickness of .050 inches and a bore size of 4.060 inches, designed to fit your 4.0L engine precisely. Because it's an MLS design, it doesn't require any additional sealants.

This gasket is a well-built option for engine rebuilds where reliable sealing is a top priority.
