Professional Products #80004 Harmonic Balancer, Street Performance, Internal Balance, 8 in., Nodular Iron, Black, Chevy, 396/402/427, Each.
Yes, there are less expensive street and SFI specification dampers, but not at this quality level, nor can they match the other features that the Professional Products line of premium dampers offers. These dampers all feature clear, white easy to read timing marks against a painted black background. In addition, timing marks are engraved every 90 which is also painted white. (90 marks not on small block Ford dampers).
Despite our extremely attractive prices, the quality of these dampers is equal to, or, in most cases exceeds that of, any other harmonic damper. You won't find any damper that is more accurately balanced or more closely machined for the correct fit than the Powerforce or Powerforce+Plus line of high performance street or SFI-spec racing harmonic dampers.
All of Professional Products dampers feature a bonding process which adheres the elastomer to the I.D. of the inertia ring and the O.D. of the hub. Through subsequent research and development we have perfected a new process that utilizes a stronger adhesive along with an improved elastomer that creates a much stronger bond. It now takes twice the force to separate the hub from the ring as it did with the previous bonding system. This current design is practically indestructible.
