Fits 03-06 WR450F, 03-05 YZ450F

The Vertex Pistons Top End Gasket Kit is designed for piston replacement and includes all necessary gaskets and seals from the base gasket up. Each kit contains the head, base, exhaust pipe, and upper end gaskets, along with valve seals and gaskets for power valve rebuilds. It provides enough components to rebuild all cylinders on multi-cylinder engines but does not include formed rubber valve cover gaskets. Constructed from high-quality materials, these gaskets meet or exceed OEM specifications.
