Head Gasket Set 02-07 Chevy 4.8L 5.3L

The Head Gasket Set 02-07 Chevy 4.8L 5.3L from MAHLE ORIGINAL/CLEVITE is a critical OEM-specification replacement for the LS-family V8 engines found in Silverado, Suburban, Tahoe, and Sierra trucks from 2002 through 2007. This gasket set addresses one of the most common failure points in high-mileage Gen III LS engines—cylinder head sealing—and is essential for anyone performing a top-end rebuild, addressing coolant leaks, or preparing for serious engine modifications. Whether you're a DIY enthusiast rebuilding a weekend warrior or a professional mechanic servicing fleet vehicles, this complete gasket set ensures proper combustion chamber sealing and prevents costly coolant loss or cross-contamination.

MAHLE ORIGINAL and CLEVITE are trusted OEM suppliers, and this head gasket set includes all the sealing components necessary for a complete cylinder head installation or refresh. The gasket set is engineered to withstand the compression pressures and thermal cycling of the 4.8L and 5.3L LS engines—blocks that regularly see 10.3:1 compression ratios and sustained RPM loads on the street or track. The precise thickness and material composition of each gasket in the set ensures zero leakage at intake, exhaust, and coolant passages while maintaining proper head torque geometry throughout the engine's service life. For builders working with boosted or naturally aspirated builds, using a quality OEM gasket set eliminates weak points in the seal stack.

This head gasket set fits 2002–2007 Chevrolet and GMC trucks with the 4.8L or 5.3L V8, including Silverado 1500/2500HD, Suburban, Tahoe, Yukon, and Sierra platforms. When installing, always follow factory torque specifications and sequence patterns—head bolts should be torqued to 22 ft-lbs in a cross pattern on first pass, then 65 ft-lbs on the second pass to ensure even clamp load and gasket compression. Proper surface preparation of the cylinder head and block decks is equally critical; both surfaces must be cleaned to bare metal and checked for warpage before reassembly. This gasket set is an investment in reliability for any LS engine project, from stock restorations to performance upgrades.
