Precision Harmonic Balancing for Modern Dodge Hemi

The ATI Super Damper for 2011+ Dodge 5.7L and 6.4L Hemi engines is the gold standard for harmonic vibration control. Designed for VVT-equipped engines, this 6.78-inch damper features a 6% overdrive ratio, providing the perfect balance of accessory performance and crankshaft protection. If you are running a modern Hemi with performance upgrades, this damper is essential for maintaining engine longevity and reducing wear on internal components.

Key Technical Features

  • Diameter: 6.78 inches
  • Overdrive: 6% increase for optimized accessory speed
  • Design: 3-ring modular aluminum construction
  • Compatibility: 2011+ Dodge 5.7L and 6.4L VVT Hemi engines
  • Belt Drive: 6-groove serpentine configuration

Modern Hemi engines are known for their power, but they also generate significant harmonic vibrations that can damage the crankshaft and main bearings. The ATI Super Damper mitigates these forces using a high-performance elastomer-bonded inertia ring, which is far superior to the factory-style rubber-bonded units. This 3-ring design is specifically calibrated for the VVT system found in 2011+ Dodge vehicles, ensuring seamless integration and improved engine response. By installing this damper, you are protecting your investment from the harmful effects of high-RPM operation and potential belt slippage. The lightweight aluminum construction also reduces rotational mass, contributing to better throttle response. Whether you are building a daily-driven street car or a dedicated track vehicle, trust GGCRACING to provide the high-quality components your Hemi deserves.
