Ferrea LS7 Hollow Stem Exhaust Valve Set

The Ferrea LS7 Hollow Stem Exhaust Valve Set includes eight precision-engineered exhaust valves designed for LS7 cylinder head applications. Each valve features a 1.615" head diameter and .313" stem diameter.

These hollow stem valves are manufactured using a specialized process that gun drills and micro-polishes the internal stem cavity, resulting in approximately 20% weight reduction compared to conventional solid-stem stainless steel valves. The reduced mass improves valvetrain control and supports higher engine speeds in applications where titanium valves are not permitted.

With an approximate weight of 84 grams per valve, this design provides a balance of reduced mass and durability for high-performance and racing environments.
