SFI Approved SoCal Damper 2001 - 2005


 SoCal Diesel is proud to introduce the Super Damper for GM Duramax Diesel Engines.

  • The Super Damper provides balanced dampening of torsional crankshaft vibrations at all RPM.
  • The Super Damper includes laser-etched degree marks and is a direct replacement for the stock OEM unit.
  • The SoCal Diesel Super Damper is especially needed in high performance and modified trucks to help protect against harmful engine harmonics.
  • All SoCal Diesel Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition use.
  • 3 piece design allows the hub, outer ring and counter weights to be serviced in the field.
  • Factory Dampers are a slip fit which has a tendency to shear the alignment pin on high HP engines.
  • The Super Damper features a press fit on to the snout of the crankshaft, making the damper an integral part of the crankshaft which increases dampening efficiency.
  • ***Super Damper Installation/Removal tool is required for proper installation. This tool can be used for many other applications.***
