1998-1999 Polaris 440 XCR Vertex Formed Exhaust Valve Bellows

Sold each

The Vertex Formed Exhaust Valve Bellows 817978 is a formed exhaust valve bellows for snowmobile engines, sold each, and listed under Exhaust Gaskets in the Engine category. The bellows seals the exhaust valve mechanism on the cylinder so exhaust pressure and heat stay in the exhaust port instead of leaking past the valve; a cracked bellows leaks exhaust and soot around the valve. The feed does not give an application list, so match Vertex part number 817978 to your engine before ordering.
