7.48 Super Damper SFI Dodge 5.7L Hemi 09-Up

The ATI Performance 7.48 Super Damper SFI Dodge 5.7L Hemi 09-Up (SKU ATI918452) is a precision-engineered harmonic balancer designed specifically for Gen III Hemi applications in 2009 and newer Dodge vehicles. This component replaces the factory balancer and addresses a critical need for engine builders and performance enthusiasts running boosted or high-RPM combinations on the legendary 5.7L platform. A quality harmonic balancer absorbs crankshaft vibrations that accelerate engine wear, reduce longevity, and compromise reliability—making this SFI-certified damper an essential upgrade for any serious Hemi build.

Engineered with internal balance technology and manufactured from robust steel with black oxide finish, the 7.48 Super Damper delivers superior dampening through a elastomer core that isolates primary and secondary crankshaft vibrations across the entire RPM band. The 7.480-inch outer diameter precisely matches factory specifications for bolt-on compatibility, while SFI 18.1 certification ensures it meets sanctioning body standards for circle track, drag racing, and street performance applications. The internal balance design eliminates the need for external counterweights, providing a cleaner engine bay aesthetic while maintaining exact OEM rotating assembly balance characteristics for 2009 and newer Dodge Hemi engines.

This harmonic balancer is ideal for engine builders preparing 5.7L Hemis for forced induction, nitrous oxide, or aggressive naturally aspirated tuning where factory-level damping falls short. Installation is straightforward on any 2009-up Dodge platform equipped with the Gen III Hemi, requiring only standard socket tools and basic mechanical competency. Whether you're building a drag strip competitor, a street beast, or simply upgrading a high-mileage engine to reduce future crankshaft damage, the ATI Super Damper provides the vibration isolation necessary to protect your investment and maximize engine lifespan at elevated performance levels.
