Professional Products 7.25 in. Balancer BB Chrysler 80013

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.

Late Big Block Chrysler Harmonic Damper. This damper is supplied as a neutral balance damper with two counterweights with the damper. 1972-'78 383 & 400, '71 383 2-bbl and '74-'78 440 (cast crank engines only) use counterweight #91015. 1970-'71 440 6-bbl and the 1971 High Performance 440 use counterweight #91016. All other Chrysler big blocks require no weight. The damper also has two extra TDC marks for either the 426 street or race Hemi. To fit the Hemi, spacer #81013 is also required. This damper will not work on the 331, 354, or 392 early Hemi but basically fits all other big block Chrysler engines including the 351, 361, 383, 400, 413, 426 and 440. Complete instructions are included with the damper.
