Precision Sealing for Stock and Mild Performance Builds

Whether you're refreshing a hard-working Duramax or addressing a head gasket failure before it turns into something bigger, the Cometic C5882-027 MLS Cylinder Head Gasket is a solid choice. Designed specifically for the right-hand side of 2001 to 2016 Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L Duramax, this gasket features a .027-inch compressed thickness and a 4.100-inch round bore. Its thinner design makes it a great fit for stock or mild performance builds where maintaining factory compression is key. It’s the type of upgrade you’ll appreciate for both daily driving and weekend towing.

Built to Handle Real-World Demands

This gasket’s three-layer multi-layer steel construction is reinforced with advanced materials like armor-clad, graphite, and galvanized steel, giving it the ability to seal even slightly imperfect surfaces. Whether your engine has some mileage on it or you're rebuilding for peace of mind, this gasket provides a reliable seal that holds up under the stress of diesel engine pressures. It’s designed to help prevent leaks, reduce the risk of failure, and keep your Duramax performing the way it should. If you’re looking for a dependable solution without going overboard, this gasket gets the job done right.
