Description

Polaris XPEDITION Valve Stem Seal Kit

Valve stem seals help control the amount of oil that reaches the valve stems while preventing excess oil from entering the combustion chamber. As the seals wear, your engine may begin to consume oil, produce exhaust smoke, or develop carbon buildup on the valves. This Polaris XPEDITION Valve Stem Seal Kit is designed for 2024-2026 NorthStar ADV and XP models equipped with the ProStar 1000 engine.

Replacing the valve stem seals during a cylinder head rebuild helps maintain proper oil control, supports efficient combustion, and contributes to long-term engine reliability.

When Should You Replace Valve Stem Seals?
