Cometic GM 6.6L Duramax Diesel 01-06 4.100 inch Bore .051 inch MLS Left Head Gasket

Cometic Gasket is a well-known name for building robust engine sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example of their work. If you're diving into the top end of your GM 6.6L Duramax diesel, specifically models from 2001-2016, this gasket is designed for the left side of your engine. It's built to handle the high output these engines are known for, ensuring a solid seal between your cylinder head and block.

This gasket is constructed from multiple layers of stainless steel, which gives it 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 (250°C) and works well with different block and head materials like aluminum and cast iron. The compressed thickness is set at 0.051 inches, and Cometic's MLS design means you don't need any extra sealants for installation, making the job more straightforward. This gasket is a solid option for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, as it can manage the shearing forces that can occur between dissimilar metals.

This specific gasket is for the left side of the engine and features a 4.100-inch bore, matching the factory specifications for many GM 6.6L Duramax applications. It's a well-built component designed to provide reliable sealing for your diesel engine.
