Product Details

The ATI Performance Products 917730 Super Damper is a high-performance harmonic balancer designed to control harmful crankshaft vibrations in high-output engines. This precision-engineered damper utilizes ATI's exclusive elastomer technology to absorb and dissipate torsional vibrations across the entire RPM range, protecting critical engine components from damaging harmonic frequencies.

Key Features:

  • Premium elastomer design provides superior vibration dampening compared to fluid or stock dampers
  • CNC-machined from high-quality steel for precise balance and durability
  • SFI 18.1 certified for competition use and safety compliance
  • Reduces stress on main bearings, rods, and crankshaft for extended engine life
  • Maintains dampening effectiveness throughout the RPM range
  • Black finish with laser-etched timing marks for accurate engine tuning

ATI Super Dampers are the choice of professional engine builders and racers worldwide, providing proven protection for street performance, drag racing, road racing, and marine applications. Each damper is individually balanced to strict tolerances and includes installation hardware.

good price, prompt delivery. no complaints.

great pricing, and easy to use web interface!

Arrived in 4 business days and cheapest price on the web for the part I got.

Love them!!! They send E-Mail conformation when order is placed and tracking number when shiped.

Awesome company. Great prices... friendly staff and fast shipping. Will use as much as possible for auto parts needs.

With money being tight, we have to do whatever we can to save a few dollars here and there. Autoplicity ended up having the absolute lowest shipped price on the item I needed, and it arrived sooner than I had anticipated! There is not much else they sell that I would need, but for others who need Magnaflow exhaust parts, I am recommending they check Autoplicity for a good price.

Awesome prices on hard to find auto parts...quick shipping..A+!

Autoplicity has the best prices around
