CORVETTELS1/LS6 HARMONICDAMPER - NON-SFI

These dampers are very similar to the 80032/90032, except they are shorter to fit the 1997-'04 Corvette. Because of this shorter length, this damper would be a good choice for engine transplants where front space is at a premium. However, this would also require the use of Corvette accessory brackets in order for the drive belts to line up. Although not required on a stock engine, these dampers have a keyway as well as a TDC timing mark with additional engraved marks every 90 degrees. These extremely high quality dampers are less expensive than any other LS1 Corvette damper available. The Powerforce street damper is made of nodular iron and the Powerforce+Plus SFI-spec damper is 1045 steel.
