Product Details

The ATI Performance Products 917369 Super Damper is a precision-engineered harmonic balancer designed specifically for 2006-2010 GM Duramax 6.6L diesel engines (LBZ/LMM). This high-performance damper eliminates harmful torsional vibration at the crankcase, reducing engine wear while allowing power to come on quicker and smoother for improved throttle response and overall engine balance.

Key Features:

  • Constructed from steel with black zinc chromate finish for durability and corrosion resistance
  • Laser-etched 360-degree timing marks for precision tuning
  • Exceeds SFI 18.1 safety specifications for high-performance applications
  • External balance design with 7.530-inch outside diameter
  • Tunable and serviceable construction for long-term reliability
  • Made in the USA with ATI's patented Super Damper technology

This harmonic balancer is an essential upgrade for modified Duramax engines, particularly for sled pulling, racing, or heavy towing applications where engine harmonics can cause accelerated wear. Note that installation requires a special installation stud and washer not included with standard puller kits (available separately).

Great price and easy to use sight

After shopping around for a specific cargo carrier, Autoplicity had the best total price by over $50 and great ratings, so I gave them a try. I received the SportRack Aero XL - A90275 last Thursday and am VERY impressed with their price and service. The cargo carrier arrived quickly (ordered Sat, rec'd Thurs) and in fine shape. I will recommend Autoplicity to my friends, and plan to shop with them for my future automotive needs.

Wanted to buy my parts on another audtion site but found the price much better on Autoplicity, and the service seems friendly.

Very pleased with product and shipping prices. Best price on the internet.Took a few to many days between order placement and shipping. Once the product was shipped the timing was very good.Talked with support-they were helpful and friendly.
