Cometic AMC 4.0L Inline 6 .080in MLS Cylinder Head Gasket - 4.000in Bore

If you're rebuilding the top end of your Jeep Cherokee, Comanche, Grand Cherokee, Wagoneer, or Wrangler, a quality head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) head gasket from Cometic is specifically made for the AMC 4.0L Inline 6 engine, featuring a 4.000-inch bore and a .080-inch compressed thickness, designed to handle the demands of this popular engine.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion and maintain a strong seal. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in tough sealing environments. This construction means the gasket requires no additional sealants, making installation more straightforward. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing needs, which is how this gasket achieves its specific .080-inch compressed thickness.

This gasket is suitable for use with both aluminum heads and aluminum blocks, or aluminum heads and cast iron blocks, as it can manage the shearing forces that can occur between different metals. It's a well-built component designed for reliable performance in your Jeep's engine.
