Sb Chrysler Exhaust Gskt

The MR. GASKET Small Block Chrysler Exhaust Gasket (SKU MRG5938) is a purpose-built header and manifold gasket designed for Small Block Mopar engines. This pair of Ultra-Seal gaskets features a steel core laminate construction with 1.000 x 1.640 inch rectangular port dimensions, engineered to seal the critical interface between cylinder head and exhaust header or manifold. Proper sealing at this junction prevents exhaust gases and coolant from leaking, protecting engine integrity and maintaining performance.

The steel core laminate design provides durability under thermal cycling and vibration while maintaining a reliable seal across wide temperature swings typical of exhaust header operation. The rectangular port configuration matches Small Block Mopar head and manifold specifications precisely, ensuring proper fitment without modification. MR. GASKET's Ultra-Seal technology is formulated to resist degradation from exhaust heat and the thermal stress experienced in this high-temperature zone. Each gasket in the pair is ready for immediate installation on the corresponding cylinder bank.

This gasket set is essential for engine builders, restoration shops, and enthusiasts performing Small Block Mopar engine assembly or header installation. Whether rebuilding a classic Dodge, Plymouth, or Chrysler performance engine, or upgrading to aftermarket headers on an existing powerplant, these gaskets ensure a clean seal that prevents exhaust leaks which would otherwise compromise engine diagnostics, fuel economy, and emissions control. Replacing worn or damaged exhaust gaskets restores proper sealing and eliminates the telltale hissing or exhaust odors that indicate header gasket failure.
