Vulcan C/R Head Gasket GM LSX LH 3.977 x .059

The Vulcan C/R Head Gasket GM LSX LH 3.977 x .059 is designed for high-performance LS and LSX engine builds, ensuring optimal compression ratios and durability in extreme conditions. This gasket is ideal for tuning street cars, building track-focused platforms, or supporting boosted drag setups, providing the sealing integrity necessary to prevent catastrophic engine failures.

Engineered by SCE Gaskets, a trusted name among engine builders, this left-hand gasket is tailored to meet the specific bore geometry and thermal demands of GM's LSX family. The gasket features a 3.977-inch bore diameter and a compressed thickness of 0.059 inches, ensuring proper clamping load and combustion seal across a wide range of operating temperatures. SCE's Vulcan C/R technology incorporates a spring-steel core with premium facing materials, effectively resisting blowby and preventing hot-gas leakage, which is crucial for high-boost applications.

This gasket is compatible with naturally aspirated, supercharged, turbocharged, and nitrous-fed LS/LSX engines, making it suitable for various applications, including street, strip, and road racing. The thinner profile helps maintain target compression ratios while allowing tuners to achieve precise piston-to-valve clearances, maximizing power output without sacrificing reliability under repeated heat cycles and pressure spikes.
