Vibratech TVD ( formerly Houdaille) invented the original viscous fluid type torsional vibration damper in 1946.  Because of it's technologically superior design, Vibratech's viscous dampers were quickly accepted by diesel engine manufacturers.

All design, engineering, testing and manufacturing continue to be performed in the USA. Every element of manufacturing is strictly monitored and controlled in our ISO 9001-2008 Certified and Registered state-of-the-art manufacturing facility located in Springville, NY.

Vibratech TVD is continuously striving to improve its products and is the only viscous diesel damper supplier that manufacturers dampers for both heavy duty diesel and high performance racing engines.  Racing is the ultimate laboratory for development of technology and testing and much of what is learned from the racing industry is applied to the heavy duty diesel damper designed and manufactured by Vibratech TVD.  Other diesel damper manufacturers around the world tend to copy and follow Vibratech TVD, the leader and original inventor of viscous dampers.

Vibratech TVD offers viscous dampers ranging from 5" to 24" for popular diesel and natural gas engines used by the trucking industry, off highway construction vehicles, marine, and stationary power applications.
