Product Overview:

Description

These Professional Products SFI Spec PowerForce Plus dampers provide more applications for a wider range of engines. All Professional Products PowerForce Plus 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, Professional Products has perfected a new process that utilizes a stronger adhesive, along with an improved elastomer, to create a much stronger bond. Professional Products dampers all feature clear, white, easy-to-read timing marks against a painted black background. In addition, they engrave a mark every 90 degrees, which is also painted white (90 degree marks are not on small block Ford dampers). You won't find any dampers that are 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.

Pontiac Harmonic Balancer.  Our two dampers for Pontiacs are dimensionally the same as the 1969 through 1979 O.E. production dampers. In order to fit this damper to a 1961-'68 engine, the use of a 1969 or later timing chain cover, water pump and related accessories are required These parts are available from wrecking yards or Year One at 800-932-7663. Late model timing covers are also being reproduced by aftermarket companies* as well. Unlike some competitive dampers, our models include the tapered machining on the outer inertia ring which allows the use of the stock pulleys. These are both outstanding dampers for the Pontiac engine and are being widely used by Pontiac enthusiasts. Both include 60
