Exhaust Manifold Gasket LS7 (1pk)

The Chevrolet Performance LS7 Exhaust Manifold Gasket (Part #12594171) is an essential OEM-specification seal designed to ensure a leak-free connection between your LS7 cylinder head and exhaust manifold. This gasket is crucial for preventing exhaust gas leakage, oil seepage, and heat loss, which are common issues in high-performance LS builds when using inferior aftermarket seals.

Engineered to withstand extreme thermal cycling and combustion pressures, this gasket can handle peak surface temperatures of 900–1,100°F under sustained load. It is made from a precision-molded composite material that resists blowout better than generic multi-layer steel alternatives, ensuring reliability for both track and street drivers.

Ideal for LS7 engine builders and Corvette C6 Z06 owners performing routine maintenance, this gasket is also suitable for anyone upgrading to a more aggressive tune on a stock 427 platform. Its lightweight profile minimizes thermal mass while maintaining structural integrity, making it a vital component for LS applications.
