Competition Series

Tractor Pulling 
Universal Fit For Taper Lock Hub

Tractor pulling engine builders long favored Fluidampr parent company, Vibratech TVD heavy duty viscous dampers. Fluidampr now takes it further with 35 years of experience developing dampers for professional motorsports. The result is exceptional, long lasting crankshaft vibration control for today’s top Pro Pullers.

In comparison, the new Fluidampr tractor pulling damper surpasses the Vibratech TVD heavy duty damper in competition use. The Fluidampr design meets SFI 18.1 safety specifications for high rpm structural rotational integrity. Inertia mass is roughly 10% greater to optimize vibration control for higher torque. Additional internal components compensate for greater thrust loads. Overall, thicker steel and laser welding the housing creates a single piece design for superior durability under high torque and horsepower.

The damper also features a more robust, 12 bolt on 4.5” b.c. mounting flange. The universal fit design requires a taper lock hub with 3.25” pilot.
