About this part

Product Details

If you're rebuilding the top end of your GM LS V8 engine, a solid set of head gaskets is crucial for a leak-free seal. This Multi-Layer Steel (MLS) gasket from Cometic is built for the 4.8L and 5.3L displacements, featuring a 3.810-inch bore and a .051-inch thickness. It's designed to handle the demands of various sealing environments and surface finishes common in these powerful V8s.

Cometic constructs these gaskets using three to five layers of stainless steel. This material choice offers increased strength and resilience, helping the gasket rebound effectively and resist corrosion over time. The outer layers are embossed and coated on both sides with Viton, a high-temperature rubber material rated for up to 482°F (250°C). This coating ensures a reliable seal even under harsh operating conditions and varying load levels, making it a well-built option for your LS engine build.

This gasket fits a wide range of GM vehicles equipped with the 4.8L or 5.3L LS V8, including popular models like the Chevrolet Silverado 1500 and GMC Sierra 1500. Always refer to the manufacturer's installation instructions for proper torque sequences and procedures.
