MOOSE OFFROAD 817848 Head Cover Gasket 2000-2025 Suzuki DR-Z400 DR-Z4S Kawasaki KLX400

Premium Molded Rubber Valve Cover Sealing

Stop annoying oil leaks at the top of your cylinder head without paying dealership prices. The MOOSE OFFROAD Head Cover Gasket, available at Moto-House MX, is a high-quality replacement for the thick, molded rubber gaskets found on the Suzuki 400cc engine platform. Whether you are performing a routine valve clearance check or a full top-end rebuild, the 817848 gasket provides a factory-perfect fit and unmatched reliability for your dual-sport, street, or off-road machine.

Engineered and manufactured in the USA, this valve cover gasket utilizes high-tech rubber materials designed to withstand the constant heat cycles and oil exposure of a high-performance 4-stroke engine. While some gaskets are flimsy, this molded rubber design provides the necessary thickness and elasticity to create a reliable seal between the head cover and the cylinder head. MOOSE OFFROAD offers this as a standalone item, giving you the flexibility to buy exactly what you need for your 2000-2025 Suzuki DR-Z400 or the new DR-Z4S models.

Expert Pro-Tip

When installing a new valve cover gasket, ensure the "half-moon" sections of the gasket are seated perfectly in the cylinder head cutouts. A tiny dab of high-temp silicone sealant in the corners of those half-moons is a common professional practice to ensure a 100% leak-free seal.
