6.4" Damper for '79 & earlier SB Ford (28.4 oz. in.) Our SB Ford dampers are the most universal dampers made. Featuring three sets of timing marks and both 3 and 4-bolt accessory pulley patterns, these dampers will fit every SB Ford engine. The early style harmonic damper fits all 1980 and earlier 289/302/351W/351C/351M/400 engines which utilize the 28.4 oz. in. c'weight. The bolt-in weight can be removed if required.

PowerForce+Plus great new street dampers are made from extremely tough nodular iron and are suitable for all street applications and mild (non SFI) racing applications. These dampers are designed to be safely revved to as high as 6,000 rpm.

PowerForce+Plus dampers are of the highest quality and are precision machined to tolerances tighter than OEM. They come with a gloss black paint finish and white timing marks for easier reading. Externally balanced dampers feature bolt-in counterweights that are precision balanced. Counterweights are included with all external dampers. All Ford dampers have three sets of timing marks to cover nearly every small block damper application. 
Note: 80006/80007 Ford dampers have  3 and 4-bolt accessory bolt patterns.

What is Bonding?When dampers are bonded, what does this mean? It means that the elastomer (rubber) that is sandwiched between the ring and the hub is bonded, or vulcanized, to metal. This is similar to the process used to bond the metal motor mounts to the rubber vibration isolaters used in these mounts.  This greatly increases the safety of the damper as most stock, and many inexpensive aftermarket dampers, are just pressed together and under heavy duty applications, the ring can rotate, moving your TDC mark from the true position, or fly off the engine. And that is very bad!
