Description

The Cometic C5489-053 is a Multi-Layer Steel (MLS) cylinder head gasket engineered for GM LS Gen-3/4 Small Block V8 engines. This gasket offers a precise .053 inch compressed thickness and a 4.100 inch bore size, making it suitable for performance applications. Constructed from five layers of high-strength stainless steel, the Cometic MLS gasket provides superior sealing and durability. The stainless steel material enhances the gasket's ability to withstand extreme pressures and temperatures, while also offering excellent rebound characteristics to maintain seal integrity under dynamic engine conditions. This design is intended to maximize engine power and performance. This specific gasket is compatible with a range of GM LS engines, including LS1, LS2, LS3, and LS6 variants. Fitment has been noted for select vehicles such as the 2006-2008 Chevrolet Trailblazer LS/LT and the 2010 Chevrolet Camaro SS. It is important to verify compatibility with your specific engine and vehicle configuration.
