GM LS 1.600 C/6 Exhaust Valve 4.915 OAL

The GM LS 1.600 C/6 Exhaust Valve 4.915 OAL by FERREA is a precision-engineered component designed for high-performance LS-series engine builds and racing applications. This exhaust valve serves as a critical element in the engine's valve train, managing the controlled release of burned combustion gases from the cylinder head. Whether you're building a street performance engine, preparing a track car, or restoring a classic LS platform, this valve delivers the durability and flow characteristics required for serious power and reliability.

Manufactured from premium stainless steel, the GM LS 1.600 C/6 Exhaust Valve features a 1.600-inch head diameter paired with a 0.313-inch valve stem and an overall length of 4.915 inches, engineered to exacting tolerances for OEM and aftermarket LS head compatibility. FERREA's 6000 Series construction uses advanced metallurgy to withstand sustained high-temperature cycling, resist corrosion, and maintain dimensional stability under extreme combustion pressures. The stainless material composition enhances thermal fatigue resistance, allowing consistent performance across wide engine speed ranges and fuel types commonly used in modified LS platforms.

This exhaust valve is ideal for engine builders, performance shops, and enthusiasts upgrading or rebuilding GM LS-series engines with valvetrains that demand superior exhaust flow and longevity. Direct fitment into LS cylinder heads makes installation straightforward during head assembly or complete engine rebuild scenarios. Whether paired with a mild street cam or aggressive race profile, the 1.600-inch head diameter optimizes exhaust port scavenging efficiency. Each valve ships individually, allowing builders to purchase exact quantities needed for their project—single replacements, complete valve sets, or staged builds.
