Exhaust Gasket Set Dodge V10 8.0L/488 Truck

The REMFLEX Exhaust Gasket Set for Dodge V10 8.0L/488 Truck is a premium graphite exhaust header and manifold gasket pair engineered to seal the D-port exhaust openings on Mopar V10 engines with precision fit and superior heat resistance. This matched pair features 1.375 x 1.438-inch openings and is purpose-built to eliminate exhaust leaks that compromise both performance and emissions control on heavy-duty Dodge truck platforms.

The graphite composition of these gaskets provides exceptional thermal durability under the extreme cylinder-head temperatures that V10 engines produce during extended hauling, towing, or off-road duty. REMFLEX gaskets are engineered to withstand the thermal cycling and vibration associated with large-displacement Mopar powerplants without degradation, chemical breakdown, or blow-out. The D-port specification ensures proper fitment to the 8.0-liter V10's cast-iron head configuration, delivering a factory-spec seal without modification. This pair replaces both driver and passenger side manifold gaskets in a single service, reducing installation time and labor cost compared to buying individual gaskets.

This gasket set is essential for owners who have removed and reinstalled their exhaust manifolds during engine rebuild, turbo installation, or other powertrain work on their Dodge V10 truck. Proper manifold sealing is critical for maintaining backpressure, fuel-injection tuning accuracy, and oxygen-sensor function. A failed or leaking manifold gasket introduces unmetered air into the exhaust stream, triggering diagnostic trouble codes and reducing throttle response. The REMFLEX pair provides a professional-grade seal that restores OEM performance characteristics and holds up through repeated thermal shock.
