Vertex Gaskets 89-92 Polaris Big Boss 250 4x6 Complete Gasket Kit w/ Oil Seals

If you're rebuilding the engine on your 1989-1992 Polaris Big Boss 250 4x6, this complete gasket kit from Vertex Pistons is what you'll need. It contains all the gaskets, o-rings, and engine oil seals specified by the OEM to get your engine back together properly. This kit also includes the formed rubber valve cover gaskets, which are often a good idea to replace while you're in there.

Vertex uses high-performance MicroPore gasket material where it's applicable in this kit. This means you're getting a well-built set of seals designed to handle the demands of your engine. While this kit covers most of your engine sealing needs, it does not include the mechanical water pump seal, so be sure to check if that needs replacing separately.
