Introducing the GMC Sierra 3500 HD Head Gasket - Right, expertly crafted by Cometic Gasket. Designed for models from 2001 to 2016, this MLS (Multi-Layer Steel) gasket offers durability and superior sealing performance for high-output engines. With a thickness of 0.060 inches and a bore size of 4.100 inches, it's the perfect fit for your engine needs.

This gasket is built from multiple embossed layers of stainless steel, each coated with Viton, a fluorocarbon rubber known for its excellent resistance to heat up to 482°F (250°C). This configuration allows the gasket to withstand the shearing forces present between aluminum heads and blocks, or aluminum heads and cast iron blocks. The multi-layer design not only enhances its strength but also provides flexibility and corrosion resistance, ensuring longevity and optimal performance under tough conditions.
