Professional Products 6 in. SB 350 SB Chevy Lightweight (Int.) 80010

Professional Products PowerForce harmonic dampers are extremely durable—and economically priced. They're built with 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. PowerForce dampers also feature white, easy-to-read timing marks against a painted black background. Each unit is accurately balanced and closely machined for the correct fit. Dozens of models are available for applications from 1955 and up. Choose the size, material, finish, keyways, and other options recommended for your vehicle.

This 6 in. harmonic balancer fits 350 c.i. Small Block Chevys and only weighs 5.1 lbs.
