Harmonic Dampers for Street and Racing.
High Performance Street Models & SFI-Spec Racing Dampers

Our line of dampers offer features not found with most other dampers. For example, our small block Ford dampers are made to the early short length so that '87 and later engines (with the 50 in. oz. damper) can be used in early chassis or street rods. We offer a line of very inexpensive spacers to adapt the short damper to later vehicles and provide the correct accessory belt alignment. Additionally our small block Ford dampers have both the three and four bolt pulley patterns on them as well as three sets of clear, easy to read white timing marks. Our small block and big block Chrysler dampers both come with extra bolt-in counterweights that provide fitment to limited production vehicles that other damper manufacturers have chosen to completely ignore.
