MOOSE RACING Top End Gasket Kit - KX450 810469

When you're rebuilding a KX450 top end, every gasket and seal matters—a single leak or improper fit can undermine your entire engine build. The MOOSE RACING Top End Gasket Kit eliminates guesswork by providing every component you need for a complete, reliable rebuild at a fraction of OEM pricing. Built from high-tech materials and manufactured in the USA, this kit gives you the confidence to get back on the track or trail without compromise.

Whether you're replacing a worn piston or running a high-compression setup, this comprehensive gasket and seal package handles the job. The inclusion of genuine OEM replacement oil seals ensures critical areas stay sealed under load, while the full complement of head gaskets, base gaskets, exhaust gaskets, and miscellaneous O-rings covers every seal point in the top end. For riders looking to boost compression affordably, the available high-compression version uses thicker (.012") base gaskets to raise compression ratios without the expense of a new piston or head work.
