Why upgrade your 6.4L 392 Hemi with performance parts?

Upgrading your 392 Hemi’s components unlocks greater horsepower and torque while maintaining reliability.

The 6.4L 392 Hemi’s robust rotating assembly and high compression ratio make it well-suited for moderate forced induction setups. When adding a supercharger or procharger, it’s important to consider fuel system upgrades, cooling enhancements, and proper tuning to maintain engine health. Planning these supporting modifications ensures your boosted build performs reliably over time.
