Our fluid dampers are very similar in design to the type sold by Fluidampr. They have an internal ring surrounded by a thin film of high viscosity silicone fluid, which allows the ring to rotate freely within the housing on nylon positioning guides. This allows the outer shell to "spin up" faster then the ring as the engine accelerates, which increases horsepower by reducing the amount of weight the engine has to move by over 33% compared a standard elastomer type balancer. Also, the housing is a one piece laser welded design, so there is never any danger of the ring coming loose or timing marks slipping. These include printed timing marks to 50 degrees, and a symmetrical pulley bolt pattern. We have designed these dampers based on detailed factory specifications, to be sure there will be no problems with fit or finish. These are NOT the same as the imported garbage many other vendors are selling. These are AWESOME quality. Take a look at the picture and judge for yourself. The chrome is so highly polished, you can see the reflection of our ceiling in the damper if you look closely.
440 Source is an official SFI approved participating manufacturer. The SFI foundation performs destructive testing on sample fluid dampers to ensure that the steel and methods of construction used meets their stringent requirements. This means they spin the sample dampers up to 12,500 RPM for over an hour, then they literally rip the metal apart while measuring how much force it takes for it to bend, stretch and finally break. SFI's minimum specifications to certify a damper to pass their 18.1 testing includes a yield strength of 40,000 pounds, a tensile strength of 60,000 pounds, and a maximum 10 percent elongation. Our fluid dampers not only passed the testing, but far exceeded SFI's minimum specs. Our yield strength was 52,000 pounds (over 30% stronger than required). Our tensile strength was an amazing 97,000 pounds (over 60% stronger than required) and our elongation was 25% (2.5 times the required minimum!) Not only do you get this kind of GUARANTEED quality, but you get it at a fraction of the cost of the name brand units.
Shown here is our new high strength steel Damper. 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.
This super cool damper bolt has a 1/2" drive socket built into it, which makes it super easy to turn over your engine by hand with a breaker bar or ratchet.
We've taken the factory original and hard to find damper bolt and made it even better by reproducing it in a high strength Grade 8 material (along with the unique heavy washer).
Another 440 Source exclusive big block Mopar part! These awesome fully CNC machined adjustable timing pointers bolt on to the front of the engine, just like a regular pointer would. They're fully adjustable, allowing you to set TDC exactly where it should be with the damper, etc you are using.
Our timing tape features a zero to 60 degree scale (plus marks every 90deg) and fits all Big Block Mopar 7 1/4" diameter dampers. These are a great high performance item that helps to solve several problems. On engraved or printed dampers (even if they have the full timing scale printed) the lettering can be hard to read against the chrome background. This tape, with big, bright white lettering against a black background makes it quite a bit easier to see when setting timing, especially down in the dark near the bottom of the engine. Second, due to tolerance stack up, it's somewhat common to find the zero mark on your damper can be off by a degree or so. By using the tape, it allows you to find exact TDC, and they apply the tape at exactly that point. This is a much better and inexpensive alternative to modifying your timing pointer, or having your damper re-degreed.
