Chev SB 400 V8 6.75" Harmonic Balancer External Balance
Product Information
SCAT harmonic dampers are not only affordable, but they are also extremely durable.
These dampers feature a bonding process which adheres the elastomer to the i.d. of the inertia ring and the o.d. of the hub, utilizing a strong adhesive along with an improved elastomer to create a much stronger bond. These high-quality PowerForce dampers also feature clear, white, easy-to-read timing marks against a painted black background. In addition, Professional Products engraves a mark every 90 degrees, which is also painted white (90 degrees marks are not on small block Ford dampers). These dampers are accurately balanced and closely machined for the correct fit.
