Overview

Professional Products Harmonic Dampers
Professional Products Harmonic Dampers

When it comes to harmonic dampers, Professional Products has become one of the industry's largest suppliers of street and SFI-certified dampers. We offer one of the most complete lines of harmonic dampers in the industry. The SFI-Spec Powerforce+Plus as well as the Powerforce line of street performance harmonic dampers provide more applications for a wider range of engines than any other harmonic damper manufacturer in a comparable price range.

Professional Products' line of harmonic dampers has features not found with most other dampers. For example, our small block Ford harmonic 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 harmonic damper to later vehicles and provide the correct accessory belt alignment. Additionally our small block Ford harmonic 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.

Powerforce+Plus SFI harmonic dampers are constructed of 1045 steel for increased durability and consistency at higher RPMs. All of our dampers feature a bonding process which adheres the elastomer to the I.D. of the inertia ring and the O.D. of the hub. Our dampers all feature laser etched timing marks against a painted black background. In addition, we engrave a mark every 90° which is also laser etched. (90° marks not on small block Ford dampers. Harmonic dampers for EFI applications do not have timing marks)
