      Note: It is possible to convert this internally balanced damper to external simply by adding optional counterweight #91005. Some big blocks may require an aftermarket timing pointer to align with the TDC mark on these dampers.

    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.
