About this part

Product Details

If you're rebuilding the top end of your 2001-2004 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the LB7 Duramax engine, this Cometic StreetPro Top End Gasket Kit is a solid option. This kit brings together all the essential gaskets and seals you'll need to get your engine back together correctly, focusing on quality materials for a dependable seal.

Cometic uses a variety of gasket materials in their StreetPro kits, including MLS (Multi-Layer Steel), AFM (Advanced Sealing Material), Aramid Fiber, and Armor Clad. For your LB7 Duramax, this kit specifically includes Multi-Layer Steel (MLS) cylinder head gaskets with a .053 inch thickness and a 4.130 inch bore. MLS gaskets are well-regarded for their ability to handle the high pressures and temperatures found in modern diesel engines, offering a strong, reliable seal that resists leaks and blowouts. The specific bore size ensures a proper fit for the LB7 engine, and the .053 inch thickness is a common choice for stock or lightly modified applications, helping to maintain the correct compression ratio.

This kit is designed to cover the critical sealing points for your engine's top end, making your rebuild process more straightforward. By providing a comprehensive set of gaskets, Cometic helps ensure that you have the right parts on hand, reducing the chances of delays or needing to make extra trips for missing components.
