MOOSE RACING Top End Gasket Kit - CR500R 810273

A top-end gasket kit is essential when rebuilding your CR500R—whether you're replacing a worn piston or performing routine maintenance. This Moose Racing kit delivers OEM-quality seals at a fraction of factory pricing, giving you the confidence to reassemble your engine without cutting corners. By using high-tech materials and precision engineering, you'll achieve a reliable rebuild that performs as intended without leaks or premature wear.

The kit includes everything needed for a complete top-end rebuild, eliminating the guesswork of sourcing individual gaskets and seals separately. If compression gains are on your agenda, the available high-compression variant uses thicker base gaskets to increase compression ratio cost-effectively—no expensive piston or head work required.
