Advanced Harmonic Dampening for 2011-2020 Duramax

The ATI Performance 7.425in Super Damper is the premier choice for owners of 2011-2020 GM Duramax trucks looking to improve engine longevity and performance. This unit is specifically calibrated to address the harmonic frequencies generated by the Duramax platform, providing unmatched protection for your engine's rotating assembly.

Key Advantages

  • Fitment: Precision engineered for 2011-2020 GM Duramax LM
  • Diameter: 7.425 inches
  • Safety: SFI 18.1 certified
  • Material: High-strength steel with black oxide finish
  • Balance: External balance for perfect operation

When you increase the power of your Duramax through tuning or hardware upgrades, the factory harmonic balancer often becomes the weak link. The ATI Super Damper replaces the stock unit with a high-performance design that effectively absorbs vibrations across the entire engine speed range. This reduction in vibration not only protects the crankshaft but also reduces wear on the serpentine belt system and front engine accessories. The black oxide finish provides excellent corrosion resistance, ensuring the damper looks as good as it performs under the hood. For diesel enthusiasts who demand the best in reliability and performance, this ATI unit is an essential addition to any build. Enhance your truck's performance and protect your engine with high-quality parts from GGCRACING.
