NOTE: Verify your specific engine code (RPO code) before ordering. Both 5.3L and 6.2L variants use this kit. VIN verification is strongly recommended to confirm correct application.

NOTE: This is the head gasket kit only. It does not include head bolts, lifters, timing components, or other engine rebuild parts.

WHY OEM? Head gasket replacement on a Gen V LS-based engine is a high-stakes repair. The GM OEM gasket uses the factory multi-layer steel (MLS) construction with the correct compression ratio thickness and fire ring placement calibrated for the specific bore and deck height of your engine. Aftermarket gaskets - even from reputable brands - can vary in thickness and sealing ring design, potentially causing compression or coolant loss after installation. Using the OEM part eliminates that variable entirely.
