Eliminate torsional vibrations to smooth out your RPM's for a quieter, smoother running engine that also results in a broader powerband and more overall power. Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations.

I just got the damper put on yesterday, I have a Southbend clutch that transfers a lot of harmonics so at idle I can't hear much difference maybe down the road I'll know more.

Made my 2003 Dodge smooth! Worth the money! No more shaking mirrors at idle and nice running down the road.

Easy to install and a lot smoother idle
Installed easy and it took out a lot of the engine vibrations, only downfall is if you have to replace your belt you have to remove the balancer.

WOW!
I cannot believe what a difference this damper made after installation. I can feel it both with my hand on the hood during idle or all the way up top inside the cab. By far one of the best mods I have done. The only issue was with myself... that I didnt upgrade sooner!

Thank you for the review. Especially on a truck with higher mileage, you can definitely feel a difference with a better dampener compared to the stock unit.

Smoothed right out
Fast shipping, was packaged great, I've only had it on for maybe 2 weeks about 300-400 miles, but love it. The vibration from the motor is noticeably less as well as the smooth acceleration from 750rpm's to 3100 rpms it was awesome. Great product. recommend as a small but important upgrade

Thank you for the review and great to hear you're able to notice such a difference. Especially as miles accumulate, the factory damper really wears out and upgrading to a viscous unit like this from Fluidampr, seriously smooths out an engine.

Money well spent, would definitely recommend this upgrade.
Put this on a 2005 2500 Dodge Ram. The results were immediate and noticable reduction in noise and vibration, especially noticable under load. Wish I had done it sooner. Also shut down belt chirp was eliminated.

Thank you for the review and notes of what you were able to notice with the upgrade. Especially as the factory damper gets fatigued, you can typically notice a big change even how it idles
