Shown above is our new high strength steel Damper. These use the offset (pre 72) pulley bolt pattern. They are supplied in a chrome finish for good looks and corrosion protection. This damper is the perfect choice for those who want a damper that looks similar and interchanges with a factory unit, but with all the design features you'd expect from a modern performance unit. First we start with 1045 steel, (a far stronger steel than the cast iron the factory used, or even the nodular iron that some cheaper aftermarket dampers use.) Then, these dampers are fully dynamically balanced at the factory.
But, we don't stop there. Even though these dampers are 100% dimensionally identical to a factory unit on the outside, there are some key differences in the manufacturing process. The number one problem with 40 year old stock dampers is that the rubber which bonds the inner hub to the outer ring is exposed on the backside of the damper. This allows it to deteriorate when exposed to ozone, engine oil/grease, etc. This can allow the outer ring to slip, causing inaccurate timing marks, a munched up timing cover, or worse the ring can come loose at high RPM and turn into a bullet. To remedy this problem, we have designed these dampers in such a way that the rubber is completely sealed inside the housing of the damper. These dampers are for internal (neutral) balance engines only, they will not work for factory cast crank (externally) balanced engines.
