Cometic GM LS1/LS2/LS3/LS6 Gen-3/4 Small Block V8 4.100in Bore .053in MLS Cylinder Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with three to five layers of stainless steel, chosen for its strength and resistance to corrosion. The .053 inch thickness and 4.100 inch bore are specific to many GM LS Gen-3 and Gen-4 small block V8 engines, including popular models like the LS1, LS2, LS3, and LS6.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps ensure a solid seal even under demanding conditions and across various surface finishes found on engine blocks and cylinder heads. This makes it a solid option for rebuilding or replacing head gaskets on a wide range of GM vehicles.

This gasket fits a broad spectrum of GM vehicles, from performance cars like the Chevrolet Camaro and Corvette to trucks and SUVs such as the Chevrolet Silverado and Cadillac Escalade. Always check the fitment guide to confirm compatibility with your specific year and model.
