Precision Performance with ATI Super Dampers

The ATI 6.78in Aluminum Super Damper is engineered to provide superior harmonic vibration control for high-performance LS1, LS2, LS3, and LS6 engines. Designed specifically for 1997-2013 Corvette (Y-Body) applications where A/C has been deleted, this 3-ring damper features a 10% underdrive ratio to reduce parasitic drag on the engine accessories, effectively freeing up hidden horsepower.

Key Technical Features

  • Diameter: 6.78 inches for optimized rotational mass.
  • Material: Lightweight, high-strength aluminum construction.
  • Underdrive: 10% reduction for improved accessory efficiency.
  • Configuration: 6-groove belt drive, specifically for non-A/C setups.
  • Design: 3-ring harmonic balancer for maximum vibration absorption across the RPM range.

Unlike stock rubber-bonded balancers that can fail under high-RPM stress, the ATI Super Damper utilizes a modular design that allows for easy tuning and rebuildability. Whether you are building a dedicated track car or a high-performance street machine, this damper ensures your crankshaft is protected from harmful torsional vibrations that lead to premature bearing wear and catastrophic failure. The precision-machined aluminum housing provides an excellent balance between weight reduction and durability, making it the preferred choice for serious engine builders. Experience the difference in engine smoothness and reliability with this premium component available at GGCRACING.
