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

The Professional Products line of dampers offer features not found with any other damper. For example, the 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. Also offered is a line of very inexpensive spacers to adapt the short damper to later vehicles and provide the correct accessory belt alignment. Additionally the 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. The 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.

#80003 SBC 400 Street Performance Damper 8"

The 80003 damper is identical in every respect to the 80002 except it includes a bolt-in counterweight which provides the proper imbalance to suit externally balanced engines. Our dampers are among the most accurately balanced dampers you can buy and unlike many other 400 dampers, ours has the correct imbalance weight to provide an accurately balanced assembly.
