About this part

Product Details

If you're rebuilding the top end of your 2005-2010 Chrysler 300 with the 6.1L Hemi engine, a solid head gasket is crucial for proper sealing. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of high-output engines, ensuring a strong seal between your cylinder head and block.

Cometic's MLS design 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 and works well with different block and head materials, including aluminum heads on aluminum or cast iron blocks. This gasket has a compressed thickness of 0.036 inches and is designed for a 4.185-inch bore, making it a well-built option for your Hemi rebuild.
