Ferrea Ford 4.6L/5.4L 24V 1.553in 4.58in 21 Deg O/S Sgl Grv S-Alloy Exh Valve - Single (D/S Only)

Ferrea is known for making high-performance valvetrain components, and this single exhaust valve is a great example of their work for Ford 4.6L and 5.4L 24-valve engines. If you're rebuilding the top end of one of these modular Ford V8s, this valve is designed to handle the demands of performance applications.

This exhaust valve features a 1.553-inch head diameter and is made from S-Alloy material, which is a strong choice for exhaust valves that see high temperatures. It's designed with a 21-degree seat angle and is a single groove type, meaning it's intended for specific applications where a single groove is required. The valve measures 4.58 inches in overall length and is an oversize (O/S) part, so it's meant to be used when the valve seat has been machined to accept a larger valve for improved flow or to repair worn seats.
