Wiseco Pistons Exhaust Valve

Wiseco Pistons exhaust valves are replacement engine exhaust valves (also called poppet valves) for powersports engines. The exhaust valve opens to release spent combustion gases from the cylinder. It then seals tightly against the valve seat during the compression and power strokes. A quality valve is important for keeping compression, power and reliability in a rebuild or refresh.

Key Features:

• Steel construction made to handle the heat and wear of the exhaust side of the combustion chamber
• Made for engine rebuilds, top-end refreshes and valve replacement
• Helps restore proper valve seating and sealing when installed with correctly serviced seats and guides
• Backed by Wiseco, a brand known for pistons and engine internals for motorcycles, ATVs and other powersports

Each exhaust valve in this product line is specific to its engine application. Choose the individual part number that matches your engine. A top-end rebuild is a good time to inspect the valve seats, guides, springs and retainers and replace any worn components.
