The Performance Diesel Damper

Fluidampr invented the viscous performance diesel damper.
No other damper tames torsional vibrations like the original Fluidampr that's made in the U.S.A.

The buzz among performance truck owners is how well Fluidampr quiets and smooths out chatter in diesel engines. These smooth running engines gain HP and Torque. So if you're driving a tuned-up diesel pick-up...you've got to have a Fluidampr.

920301 Specifications:

  • Material = Steel
  • Black Zinc Finish
  • O.D = 9-1/4"
  • WT. lbs. = 23
  • Balance = Internal

It's important for the damper on your diesel engine to function properly. Stock elastomeric dampers have a short life span and do not control torsional vibrations at all RPM's. The rubber rings in stock dampers deteriorate. Fluidampr offers a superior performance that lasts.


 Stock Damper








A new Fluidampr on your diesel truck will not only protect your engine from destructive but will also increase TORQUE & HORSEPOWER. High performance diesel engines running chips and programmers are exceptionally vulnerable to torsional vibrations. Save your crank & more by installing a new Fluidampr today.

Easy install

This part was pretty easy to install. But I recommend to not take the belt off, just take loosen the tensioner, and take it off of the alternator or the power steering pulley. Because for me at least, I could not get the belt to pass through between the top of the new damper, and the fan clutch. But other than that, it's a straight forward install. I found that the bolts are torqued to 92 ft-lbs. It was hard to notice any difference that this made on my truck, other than it doesn't vibrate near as much. But I hear that its good for your engine.
Excellent product

All claims for this product are very true. My 03 runs so smooth and sounds like a real power house. Im very pleased with the money spent and would recommend it to anyone running mods. I run a smarty with a fass 150 and with the fluidampr they are in perfect harmony. Its a huge difference compared to the stock damper. Take that old hunk of junk off and GET A FLUIDAMPR!! Thanks XDP for offering such a great product at a price that cant be beat.
Very impressed
