MOOSE RACING Top End Gasket Kit - CRF450 810278

A top-end rebuild demands precision—factory gasket sets from OEM suppliers come with premium pricing that doesn't reflect the quality. The MOOSE RACING Top End Gasket Kit delivers OEM-equivalent reliability and fit at a fraction of the cost, using high-tech materials engineered for durability. Whether you're replacing a worn piston or refreshing your CRF450's top end, this complete gasket and seal set eliminates the guesswork and ensures a leak-free, properly sealed engine.

Built in the USA and designed specifically for the Honda CRF450, every gasket, O-ring, and seal needed for a confident rebuild is included—from valve seals and head gaskets to base, exhaust, and tensioner gaskets. For riders looking to bump compression without expensive machine work, MOOSE also offers high-compression variants with .012" thicker base gaskets, giving you a cost-effective performance upgrade.
