Exhaust Gasket Dodge 5.7 Hemi

The MR. GASKET Exhaust Gasket for Dodge 5.7 Hemi engines (Part Number 7594) is a premium-grade header and manifold gasket engineered for Gen III Hemi platform vehicles. This Ultra-Seal gasket set delivers a reliable seal between exhaust manifolds and cylinder head ports, preventing exhaust leaks that degrade engine performance and fuel economy. The 1.450 x 1.470 inch rectangular port geometry matches OEM Mopar specifications precisely, ensuring proper fitment on 5.7L Hemi applications without modification.

Built with a steel core laminate construction, this gasket pair resists thermal cycling and maintains compression under the extreme temperatures of exhaust gas flow. The laminated steel design prevents blowout and provides consistent clamping force across repeated heat cycles—critical for high-output or modified Hemi engines that see sustained elevated exhaust temperatures. At just 0.4 pounds total weight, the pair fits easily in any technician's toolkit and installs in standard fashion without special hardware or adapters.

Buyers performing exhaust manifold replacement, header installation, or addressing existing manifold leaks on Dodge trucks and performance vehicles will find this gasket set essential for a factory-correct seal. The Mopar Gen III Hemi platform spans multiple generations and applications—from Dodge Ram trucks to Chrysler muscle cars—making a genuine, properly-fitted gasket crucial for preventing costly coolant leaks and secondary damage. Technicians and DIY builders who prioritize first-time reliability over cheap alternatives specify MR. GASKET's proven laminate design to avoid repeat teardowns.
