This is a set of two Ferrea exhaust valves designed for 1984-1998 Harley-Davidson Evolution engines. These valves feature a 1.625-inch head diameter and a 0.31-inch stem diameter, with a hollow stem construction.

Ferrea valves are known for their well-built construction, using high-quality materials to withstand the demands of engine operation. The hollow stem design helps reduce overall valve weight, which can lead to improved valve train stability at higher RPMs. This is important for maintaining consistent engine performance and preventing potential issues under stress.
