MOOSE RACING Top End Gasket Kit - CR450/480R 810270

A top-end rebuild demands precision gaskets and seals that won't compromise engine integrity or leak under pressure. The MOOSE RACING Top End Gasket Kit eliminates guesswork with a complete, U.S.-manufactured set engineered specifically for the CR450/480R platform. Whether you're refreshing worn seals after high-mileage use or building a fresh short-block, this kit delivers OEM-quality components at a fraction of OEM pricing.

The high-compression variant (.012" base gaskets) offers a practical path to increased compression without costly piston upgrades or cylinder head modifications—ideal if you're chasing additional power without major fabrication.
