SBC Timing Cover Gasket Set w/Thick Front Seal

The SBC Timing Cover Gasket Set w/Thick Front Seal from Cometic Gaskets is purpose-built for Small Block Chevy engines requiring a comprehensive OEM-replacement gasket solution. Whether you're rebuilding a tired 350 or refreshing your street machine's top end, a proper timing cover gasket kit prevents oil weeping and maintains crankcase integrity during assembly. This composite gasket set includes the critical thick front seal—a reinforced component that bears the brunt of engine pressure and thermal cycling—ensuring your timing cover stays leak-free for years of reliable operation.

Cometic Gaskets engineered this kit with composite material construction, which offers superior sealing performance compared to traditional cork and rubber compounds. The thick front seal specification is critical because it experiences the highest stress concentration where the timing cover meets the engine block and crankshaft snout; a thicker profile resists blowout and permanent deformation under sustained boost, high RPM, or aggressive thermal conditions. The complete gasket set includes all necessary sealing surfaces for the timing cover assembly, eliminating the need for multiple purchases and ensuring all components work in harmony during installation and operation.

This gasket set is essential for any Small Block Chevy rebuild—from stock restorations to modified performance engines—making it a trusted choice among mechanics and DIY builders. Installation requires only basic hand tools and attention to proper torque sequencing; Cometic's composite construction forgives minor surface irregularities while maintaining a tight seal. Compatibility spans the full range of SBC applications, including 283, 305, 327, 350, and 400 cubic inch engines, making this kit a versatile solution for garage builds, race prep, and professional engine shops.
