Athena Top End Gasket Kit for GasGas, Husqvarna and KTM (P400270600088)

The Athena P400270600088 Top End Gasket Kit is designed for professional, semi-professional, and amateur riders who refresh the engine before a race or during the riding season. This engine gasket set provides the essential top-end sealing components needed for a reliable rebuild and helps support consistent performance during demanding off-road use. It is compatible with select GasGas, Husqvarna, and KTM applications; verify fitment with your specific model and engine before ordering.
The kit includes a premium MLSS head gasket engineered for dependable sealing under high engine temperatures and operating pressures. It also includes two or more base gaskets in different thicknesses, giving the rider or engine builder flexibility when setting compression and cylinder height. This adjustment allows the engine to be configured for standard pump gas with stock compression or race fuel with a higher compression setup, depending on the intended application and tuning requirements.
Athena is recognized for producing high-quality powersports engine components, and this P400270600088 kit is built to support precise top-end service. Selecting the appropriate base gasket thickness can help achieve the desired compression ratio while maintaining proper engine assembly specifications. Always follow the manufacturer’s service procedures, use the correct torque values, and inspect mating surfaces before installation.
This kit does not include valve stem seals, rubber components, shims, or additional fiber gaskets. Those items must be sourced separately if required for the engine service. Confirm the application, model year, engine configuration, and gasket requirements before installation to ensure the correct rebuild components are used.
