Cometic GM LS9/LSA Gen-4 Small Block V8 .052in MLX Cylinder Head Gasket - 4.100in Bore - RHS

When you're rebuilding the top end of your GM LS9 or LSA Gen-4 small block V8, you need a head gasket that can handle the pressure. This Cometic MLX head gasket is built for those high-output engines, ensuring a solid seal between your cylinder head and block.

What you get here is a multi-layer steel gasket, which means it's made up of several layers of stainless steel. This construction gives it increased strength and the ability to rebound, helping it resist corrosion and withstand the forces created when mating different metals, like aluminum heads to cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it ideal for demanding sealing environments. The center layer is uncoated stainless steel, and its thickness is what determines the gasket's overall compressed operating thickness, which is 0.098 inches for this specific part. These gaskets are designed to seal effectively without needing any additional sealants.

This gasket is a direct fit for your 2009-2015 Cadillac CTS, as well as certain Camaro and Corvette models from similar years. It's designed for a 4.100-inch bore, and its MLX construction means it's ready for serious performance without fuss.
