Fluidampr BBC Int Balanced Dual (3/16in & 1/4in) Keyway Harmonic Balancer Adapter Hub (Hub Only)

If you're working on a Chevy 396-427ci engine with internal balance and dual keyways, this harmonic balancer adapter hub from Fluidampr is what you need. It's designed to fit specific Fluidampr damper part numbers, ensuring a proper connection for effective vibration control. Repeating the process of removing and installing a damper can sometimes affect its performance, so having the right adapter hub helps maintain the recommended press fit of 0.0005 to 0.0015 inches.

This hub is built to work with Fluidampr models #800131 and #80257E, specifically for applications requiring both a 3/16-inch and a 1/4-inch keyway. It's a well-built component that ensures your Fluidampr harmonic balancer is installed correctly and stays securely in place, which is crucial for managing engine vibrations and keeping your engine running smoothly.
