A Gasket That Keeps Up With Your Duramax

When you're rebuilding or upgrading the right-hand side of your 6.6L Duramax, the Cometic C5882-051 MLS Cylinder Head Gasket gives you the confidence to push harder without sacrificing reliability. Designed for 2001-2016 Silverado and Sierra 2500HD and 3500HD trucks, this gasket features a .051 inch compressed thickness and a 4.100 inch bore for a precise fit in high-demand builds. The multi-layer steel construction is engineered to handle the intense pressures and temperatures that come with heavy towing, hard throttle pulls, or daily-duty diesel performance. It’s a solid choice whether you're chasing durability or upgrading for better sealing performance.

Reinforced to Seal Tight and Hold Strong

This gasket uses a three-layer design that combines durability with flexibility, making it perfect for sealing surfaces that aren’t perfectly smooth or flat. Reinforced with advanced gasket material compounds like galvanized steel and graphite, it forms a tight seal that holds up even when the engine is under full boost or extended stress. If you're putting in the time to do your top-end work right, this gasket helps make sure you only have to do it once. Whether you’re building a reliable workhorse or stepping into higher performance territory, Cometic’s attention to detail gives your build the foundation it needs to hold together under pressure.
