SBC LT1 Exhaust Gasket

The SBC LT1 Exhaust Gasket by FEL-PRO is an OEM-quality replacement gasket engineered for General Motors LT-series engines from 1992–1997 model years. This pair of gaskets seals the critical junction between the exhaust header or manifold and the cylinder head, preventing exhaust leaks that compromise engine performance and increase emissions. Whether you're performing routine maintenance, addressing a leaking manifold, or rebuilding an engine, this gasket delivers the reliability that professional technicians and serious enthusiasts expect.

Manufactured by FEL-PRO, a leader in gasket technology, the SBC LT1 Exhaust Gasket features a steel core laminate construction designed to withstand the extreme thermal cycling and pressure cycles inherent to exhaust systems. The gasket measures 1.390 x 1.410 inches at the D-port opening, matching OEM specifications precisely to ensure proper sealing without modification. The laminated steel core prevents blowout and separation under high-temperature conditions, while the composite facing materials conform to port surfaces and create an airtight seal that lasts. This construction method has become the industry standard for header and manifold gaskets across domestic and import platforms.

Owners of 1992–1997 GM LT-series powered vehicles—including Camaros, Firebirds, and Corvettes—will recognize the OEM gasket dimensions and specifications immediately. Installation is straightforward on factory manifolds and common aftermarket header systems that maintain stock port geometry. The pair format accommodates both exhaust banks, eliminating the need for separate purchases and ensuring consistent sealing performance across the engine. For those seeking a direct replacement that restores factory-correct exhaust sealing without guesswork, this FEL-PRO gasket delivers proven durability and thermal stability.
