Product Details

The Fluidampr 800121 is a high-performance harmonic balancer engineered for big block Chevy (BBC) engines with external balance configurations. This precision damper utilizes advanced viscous damping technology to control destructive torsional vibrations across the entire RPM range, protecting your crankshaft and extending engine life.

Key Features:

  • Viscous damper design effectively controls harmful torsional vibration from idle to redline
  • Engineered for externally balanced BBC applications
  • Dual keyway design provides timing adjustment flexibility
  • CNC-machined from high-grade steel for precise balance and durability
  • Corrosion-resistant black zinc finish with engraved timing marks
  • SFI 18.1 certified for racing applications
  • Maintenance-free operation for long-term reliability
  • Made in USA

Fluidampr's patented viscous damping technology reduces stress on engine components, improves ignition timing accuracy, and helps unleash hidden torque and horsepower. Essential protection for modified engines where factory harmonic balancers may be inadequate. Trusted by professional engine builders and racers worldwide.

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

very fast processing received product within a few days. fair prices. will do business with again.

Fast shipping, very helpful staff, product was in stock at Autoplicity and I couldn't even find it at any other supplier. Thanks Autoplicity!

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.

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!!
