Product Details
Cometic Gasket is well-known for making dependable engine sealing components. This Multi-Layer Steel (MLS) head gasket is built for demanding applications, offering a robust seal for your Lexus or Toyota engine. It's designed to handle the high output engines found in vehicles like the Toyota Tundra and Lexus LX470, ensuring a solid seal without needing extra sealants.
This gasket is constructed from multiple layers of stainless steel, which gives it strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in harsh sealing environments. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.040 inch compressed thickness on this particular gasket. This design makes it suitable for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can occur between different metals.
This is the right-side gasket, and it's designed for a direct fit on a range of Lexus and Toyota models. If you're rebuilding the top end of your engine, this MLS gasket is a well-built option that offers reliable sealing performance.
