Product Details

The ATI Performance Products 917211 Super Damper is a high-performance harmonic balancer engineered specifically for GM LS1 engines with a 1.483-inch crankshaft snout. This premium damper features an aluminum outer shell with a steel crankshaft hub and steel inertia weight, combining lightweight construction with exceptional durability for demanding performance applications.

Key Features:

  • 7.074-inch outside diameter with 3-ring design for maximum vibration dampening
  • Aluminum shell construction with steel inertia weight containing computer-machined grooves that retain precision-durometer O-rings dyno-tested for this application
  • Internal balance configuration with 2.280-inch counterbore designed for dry sump systems
  • Black zinc chromate finish resists corrosion and provides a professional appearance
  • Laser-engraved 360-degree timing marks for precise ignition timing adjustment
  • Exceeds SFI 18.1 safety certification requirements
  • Tunable and rebuildable design for long-term performance
  • Uses standard-length crank bolt with mandrel mounting to three pulley holes

Designed exclusively for high-RPM performance engines (6,000+ RPM), this ATI Super Damper effectively eliminates torsional crankshaft vibrations that rob horsepower and cause premature engine wear. The patented design has been proven through extensive testing in Winston Cup competition and drag racing applications. Total weight is 6.25 lbs with 4.5 lbs rotating weight. Sold individually, mounting hardware not included.

Bought a Husky trunk liner for my Civic. Autoplicity had the lowest price I could find, plus I received it in two days. Only problem I had was that their website had a problem with the part fit check. Although the description and part number was for the 2012 Civic, the part check said it would not fit. Had to wait until Monday to call customer service to verify that it would fit before I ordered. Would definitely order from Autoplicity again.

It was great

Awesome service, lowest price around. Great customer service

Easy to deal with, lowest price and included quick shipping.

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Quick and efficient, Thank You!

Great selection if parts, fast shipping!
