The power strokes of an engine put a pulsing pressure on the crankshaft. Each stroke exerts a torsion force, which causing deflections in the crankshaft webs with an equal rebound. This can result in fatigue and cracking, ultimately leading to a failure and an expensive repair. To solve the problem manufacturers generally fit a harmonic damper. The damper dissipates the energy of the vibration and helps to protect the crankshaft.
There are two potential problems with harmonic dampers. The first is the fact that they are heavy and they can take up a lot of space, which is a disadvantage when a vehicle needs to be lightweight and there is limited space available.
The second problem is the fact that each harmonic damper needs to be tuned to the specific engine and drive-train used in the vehicle. In order to decide which part to use, a complex mathematical calculation is required. If any part is changed, whether it is the whole engine, the clutch or a flywheel, the damper will also need changing. This can be time consuming and increases the cost.
The Sterling Rattler was designed to offer a better solution. The component opposes the torsional forces rather than absorbing them. This means you can choose a model for the specific engine and change other components more freely without needing to replace it as well. This offers major benefits, and as an added bonus it can be attached to either end of the crankshaft to suit spatial availability.
This outstanding product and can be used on a wide array of vehicles, and it can be constructed from super light alloys for race cars when weight savings are required. The Rattler has an excellent pedigree and track record of success, and is fast becoming a must have for discerning vehicle owners.
