Ferrea 84-04 Harley-Davidson Evolution 1.615in Head 0.31in Stem Dia Comp Exhaust Valve - Set of 2

This is a set of two Ferrea competition exhaust valves designed for 1984-2004 Harley-Davidson Evolution engines. These valves are crucial for controlling the flow of exhaust gases out of your engine's combustion chambers. When your engine is running, these valves open and close precisely to let the spent fuel and air mixture escape, allowing for the next cycle to begin.

Ferrea is known for making well-built engine components, and these valves are no exception. Each valve features a 1.615-inch head diameter and a 0.31-inch stem diameter, which are specific dimensions important for proper sealing and airflow within the cylinder head. Using valves that meet the correct specifications ensures your engine can breathe efficiently, which is key for performance and reliability, especially in a performance-oriented application like a Harley-Davidson Evolution engine.
