Exhaust Manifold Gasket Set Dodge 5.2l/5.9L Mag.

The Exhaust Manifold Gasket Set for Dodge 5.2L and 5.9L Magnum engines is a precision-engineered replacement component designed to seal the junction between the exhaust manifold and cylinder head. This gasket set (part number C5558-064) features rectangular ports measuring 1.195 x 1.675 inches and is constructed from graphite material, which provides superior thermal stability and sealing integrity under the high-temperature cycling of the exhaust system. Compatible with Small Block Mopar applications, this two-piece set addresses the critical sealing challenge that develops as OEM gaskets degrade from repeated thermal expansion and contraction cycles.

Graphite gasket material offers distinct advantages in exhaust applications. Unlike softer materials, graphite maintains its sealing properties across the temperature extremes encountered in exhaust passages, resisting both the high heat of combustion blow-by and the stress cycles of engine operation. The precise port dimensions ensure proper alignment with both the manifold ports and cylinder head ports, eliminating gaps that cause exhaust leaks. A degraded or missing manifold gasket allows combustion gases to escape before entering the exhaust system proper, resulting in power loss, increased emissions, and acoustic signature changes that alert experienced technicians to the underlying problem. This gasket set is the matched pair required for complete sealing across both cylinder banks.

Technicians performing exhaust manifold service on Dodge vehicles equipped with the 5.2L or 5.9L Magnum engine—whether during routine maintenance, manifold replacement, or gasket renewal—will find this set essential for proper engine sealing. The compact weight and dimensions make installation straightforward when combined with manifold removal and reinstallation procedures. Buyers sourcing OEM or OEM-equivalent gasket sets for their Mopar engine platform should verify compatibility with their specific engine displacement and manifold type before purchase. Proper gasket installation requires clean mating surfaces, correct fastener torque sequencing, and verification of seal integrity before engine startup.
