Fluidampr Universal Tractor Pulling Internally Balanced Damper (w/o Pre-Drilled Bolt Holes)

This Fluidampr damper is built for the extreme demands of professional tractor pulling competition. You get the damper itself, which is precision CNC machined from high-grade steel and features a corrosion-resistant black zinc finish. It's designed to control harmful torsional vibrations across the entire RPM range, which helps reduce wear on critical engine components and lowers the risk of crankshaft failure. This means you can expect improved engine timing and potentially unleash lost torque and horsepower.

Fluidampr's viscous damper design is a well-known approach for managing vibrations. This particular unit is competition-built and internally balanced, featuring laser-engraved clockwise and counter-clockwise timing marks for easy setup. It's SFI 18.1 certified, meeting the safety standards required for many racing applications. Because it's designed for competition, it requires a taper lock hub with a 3.25-inch pilot and will need to be drilled for bolt holes, so be prepared for that step during installation. There's no maintenance required for this damper, and it's trusted by leading performance diesel engine builders.

This damper is a substantial piece, weighing 37 lbs and measuring 12-3/8 inches in diameter. It's made in the USA and comes with a black zinc chromate finish for corrosion resistance. While it doesn't include a pulley or pre-drilled bolt holes, its robust construction and vibration-controlling capabilities make it a solid choice for serious tractor pulling applications.
