Professional Products 80012 PowerForce street harmonic damper.
Fits small block Chrysler V8s.
Power Force street harmonic dampers from Professional Products fit more applications with fewer part numbers than other brands because they have engineered them to be more universal and fit more applications than anyone else. They feature bolt in counterweights that are accurate
to +/- 2 grams, accurate crank bore for a precise, press on fit, and less than .005" runout. Most dampers have 60 degrees of bright white timing marks against a high quality, semi-gloss black finish, and both the hub and the inertia ring are made of tough 1045 steel on SFI spec dampers, and nodular iron on street dampers.
Small block Chryslers utilize one of four different dampers. One is neutral balance and the other three are externally balanced with different weights. This damper fits the neutral balance engine "as is" and comes with three counterweights to fit each of the other three engines. The instructions specify which weight to use and include a tube of thread sealant.
Not recommended for use above 6500 rpm.
