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.

Chevy 400 Small Block 6 3/4" SFI Harmonic Damper. This unique design damper is for use on externally balanced small block Chevy engines. This would typically include 383 and 400 cid assemblies. Only a few damper manufacturers offer a small 6-3/4" damper for these engines and those dampers are usually very expensive. Our models, like all of our dampers and other products, are very high quality products at very affordable prices. Note that although this model damper features a bolt-in counterweight, the damper cannot be used without the weight. Due to the windows cut in the front face of the damper, if the counterweight is removed, the damper is still not a neutral balance damper. If you need a neutral balance 6-3/4" damper, use our 80000 or 90000 models.
