Exhaust Gasket Mopar 5.9 Cummins Turbo Up-Pipe

The Exhaust Gasket Mopar 5.9 Cummins Turbo Up-Pipe is a critical OEM-replacement seal designed for 1989–2006 Dodge Ram full-size trucks equipped with the legendary 5.9L Cummins diesel engine. This four-bolt graphite gasket prevents exhaust leakage at the turbocharger intake flange, where combustion pressures and thermal cycling demand a reliable, precision-fit seal. Whether you're replacing a failed gasket, installing an aftermarket turbo system, or rebuilding your turbo assembly, this gasket ensures a tight connection that eliminates costly exhaust leaks and maintains peak boost delivery.

Manufactured to OEM specifications with graphite facing, the Exhaust Gasket Mopar 5.9 Cummins Turbo Up-Pipe withstands the extreme heat and pressure cycling inherent to diesel turbocharging—typically 400–600°F exhaust temperatures with fluctuating boost loads. Graphite composite gaskets excel in high-temperature diesel applications because they maintain their seal integrity across thermal expansion cycles that would degrade conventional paper or rubber materials. The four-bolt flange pattern ensures perfect alignment with OEM or aftermarket turbo mounting points, delivering a factory-tight seal without overtightening or gasket creep.

Cummins diesel owners performing turbo replacement, repair, or upgrade work will find this gasket essential for restoring exhaust system integrity. Installation requires removal of the turbocharger or up-pipe assembly, positioning the new gasket on the intake flange, and torquing all four bolts evenly to prevent uneven compression. This single-use gasket is compatible with stock 5.9L Cummins turbos and most common aftermarket turbocharger upgrades on first and second-generation Dodge Ram trucks (1989–2006). Always replace the gasket whenever turbo work is performed to avoid repeat disassembly and ensure reliable, leak-free operation under load.
