Where is Fluidampr and Streetdampr manufactured?

Fluidampr and Streetdamper products are manufactured 100% in the USA by Vibratech TVD, a division of Horschel Brothers LLC in our ISO 9001:2015 certified facility in Springville, NY.

Why should I steer clear of cheap Fluidampr/Streetdampr imitations?

Don’t be fooled by a product that looks like Fluidampr or Streetdampr and is even advertised as "Fluid Damper." The bottom line is this product is a cheap imitation. These imitations are not manufactured to Fluidampr’s exacting tolerances and are not backed by Fluidampr’s exclusive money back guarantee. Vibratech’s evaluation of these viscous damper imitations has shown an inadequate fluid fill, making imitations less than effective at controlling crankshaft vibration. They are inappropriately packaged, which could cause damage in transit and rusting. Genuine Fluidampr and Streetdampr brands are always advertised with a registered trademark or the well-known logos, and are stamped with the brand name on the product and on the packaging. All Fluidampr products are made in the U.S.A.

Will the silicone fluid wear out over time?

The fluid inside the Fluidampr will NEVER deteriorate in a high performance race or street application. The fluid is good for the life of the engine.

Will the silicone fluid used inside the damper turn to gel?

No. The silicone fluid used inside Fluidampr and Streetdampr is practically a gel to begin with. In a performance application, the silicone fluid is GUARANTEED against deterioration, for as long as you own Fluidampr or Streetdampr. The silicone fluid is clear in color and is very thick. The silicone fluid is 45,000 times thicker than 30 weight motor oil. In fact, the silicone fluid is not like oil at all. It is sticky to the touch.

What is crankshaft torsional vibration?

Every time a cylinder fires, the connecting rod hammers the crankshaft, making it twist as well as spin. After every twist, there’s a rebound as the crank unwinds. This twist/rebound cycle is known as torsional vibration and if not controlled, it will result in rapid bearing and crank journal wear and can lead to a broken crankshaft.

What's the problem with a stock damper?

Stock dampers are tuned for maximum effectiveness with a stock rotating assembly under stock conditions. When the pistons, connecting rods, or crankshaft are changed or modified, or normal rpm range is increased, the effectiveness of a stock damper is reduced.

What causes the inertia ring on a stock damper to move on a high performance street application?

In a stock damper, inertia ring slippage is usually due to deterioration of the rubber strip. As the stock damper ages, the rubber strip begins to crack and lose its grip, in essence it becomes “overworked.” Also, rubber is a poor dissipator of heat. The more severe the crankshaft vibration, the more heat builds up. This causes the damping characteristics to change, which could lead to damper failure over time. This is why it is always important to inspect your damper, paying special attention to the condition of the rubber.

What are the key benefits of using a Fluidampr?

A good aftermarket damper protects your crank. Fluidampr is in a class all by itself, because it is designed to provide maximum control of all engine harmonic vibrations, regardless of the rpm at which they occur and regardless of the crankshaft’s natural frequency. This translates to maximum protection of the crank, main bearings, related engine components and more consistent power output. Also, Fluidampr is maintenance and repair free. Fluidampr is effective on both race and street applications.

Can Fluidampr's timing marks move?

No. Fluidampr’s timing marks are CNC machined and cannot physically move. Inertia ring slippage is a common problem with stock dampers and also a sign that harmonic vibrations are not being properly controlled.
