ATI Performance Products, Inc. is proud to introduce its all new Super Damper (Part # 918483) for the 2015+ HEMI Hellcat 6.2L Supercharged engine for street and high performance racing applications. The new aluminum-shell, steel-hub damper is a direct fit replacement for the stock OEM unit and is better capable of handling a wider variety of driving habits that Hellcat owners will put their new cars through. OEM dampers are optimally tuned to a narrow band of perceived normal driving conditions and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges and exceed SFI 18.1 Safety Certification for competition use

ATI Performance Products, Inc. is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and strip applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail, and rigorous testing under race conditions.

The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chrysler, Dodge and Mopar Engines - including the new HEMI! 
Whether you race or just drive on the street, ATI's harmonic balancers are the perfect choice.

  • Eliminates torsional crankshaft vibrations
  • Exceeds SFI 18.1 specs
  • Black zinc chromate finished
  • OEM equipment on 392 Mopar Crate Engines
  • Tunable, rebuildable, and extremely efficient at ALL RPM
  • Laser engraved 360° timing marks

Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. This inertia weight has six (2-ring design) or eight (3-ring design) computer machined grooves to retain the proper durometer O-rings (dyno tested for each application).
