Product Details

The Fluidampr 800181 is a high-performance viscous harmonic damper engineered for big block Chevy (BBC) engines with external balance requirements. This precision-engineered damper features dual keyway slots for enhanced timing flexibility and accurate installation positioning.

Key Features:

  • Viscous damper technology controls harmful torsional vibration across the entire RPM range
  • External balance configuration specifically designed for BBC applications
  • Dual keyway design allows for precise timing adjustments and installation flexibility
  • CNC machined from high-grade steel for exceptional durability and precision balance
  • Corrosion-resistant black zinc finish with clearly engraved timing marks
  • SFI 18.1 certified for competition use
  • Maintenance-free operation—no periodic servicing required
  • Made in USA with premium quality materials and manufacturing

Unlike elastomer-style dampers that can deteriorate over time, Fluidampr's viscous technology provides consistent performance throughout the life of your engine. The advanced damping system reduces crankshaft stress, minimizes bearing wear, and helps unleash hidden torque and horsepower by stabilizing the rotating assembly. This damper is trusted by professional engine builders and racers worldwide for its proven ability to protect high-performance engines from destructive torsional harmonics.

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

i was skeptical about this site but after reading the reviews and them having the lowest price i could find for my part i pulled the trigger and wasn't disappointed. fast shipping and low prices with great customer service will shop with them again if they have what im looking for.

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!

Excellent and very quick service. I could not find this product in stock from any other supplier so I kept hunting. I found Autoplicity and from now on they are the first company I will try. Thank you.
