Application: Ford 2008-2010 Powerstroke 6.4L Diesel

ATI Performance Products is proud to introduce its new Super Damper (Part # 918887) for the 2008 to 2010 Ford Powerstroke 6.4L diesel engine for street and performance applications. This new 8.3-inch damper application is a direct bolt on replacement for the OEM unit. The 6-rib drive on the rear is slightly oversize (7%) from stock and will require a longer belt. The larger size allows the maximum size damper for this engine and the maximum amount of torsional vibration protection. The 8-rib pulley for your accessories is stock size. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges and exceed SFI 18.1 Safety Certification for competition use. As with all ATI Dampers, this damper is fully rebuildable and never needs to be completely replaced as each part can be serviced through its lifetime.


  • Steel Shell
  • 8.32" O.D.
