Fluid damper - Black - New

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. Over the last two decades, we've sold many thousands of them and have found them to be one of the best quality dampers on the market, AND at a great price. Take a look at the picture and judge for yourself. These dampers are for internal (neutral) balance engines only, they will not work for factory cast crank (externally) balanced engines. We recommend using our 109-1526 Damper bolt with these.
