Description
A top-end gasket kit is essential maintenance for any Polaris snowmobile running hard—whether you’re pushing your RMK, Fusion, or Switchback to the limit on the trail or in competition. Worn or degraded gaskets compromise compression, increase blow-by, and risk catastrophic coolant and oil leaks that sideline your sled. The PROX Top End Gasket Kit delivers OEM-quality sealing to restore engine integrity and keep your powerplant running at peak efficiency.
