Ferrea Chevrolet LS1 1.55in 0.313in 4.915in Super Alloy Exh Valve - Single (Drop Ship Only)

This is a single Ferrea Super Alloy exhaust valve designed for Chevrolet LS1 engines. It measures 1.55 inches in diameter for the valve head, has a 0.313-inch stem diameter, and an overall length of 4.915 inches. These valves are built from a high-strength super alloy, chosen for its ability to withstand the extreme temperatures and pressures found in performance LS1 applications.

Using a super alloy like this helps ensure durability and consistent performance, especially when the engine is pushed hard. The material is selected for its resistance to heat and wear, which is critical for exhaust valves that deal with the hottest gases exiting the combustion chamber. This valve is a direct replacement for stock or performance builds where reliability under stress is a priority.
