      Notes: The Corvette models of the LS1 damper are shorter than the 80032/90032 so may be more desirable for engine swaps where space is at a premium. If this swap is made, Corvette accessory mounting brackets will also need to be used to assure proper accessory drive belt alignment.

    Professional Products Powerforce Dampers are designed to fit a wide range of engine applications. Powerforce Dampers come internally or externally balanced from the manufacturer but allow additional bolt-on counterweights. With this feature, these Dampers provide high flexibility in switching to different applications and that require more or less balance. This allows one Damper to be used on multiple engines. Professional Products gives a major competitive advantage with versatility combined with quality not found with any other company.
