Fluidampr Chevy 396-427 CID V8 w/ one 3/16 and one 1/4 key slot Steel Internally Balanced Damper

Built from precision CNC machined steel components, this Fluidampr harmonic balancer is designed to control torsional vibrations across the entire RPM range. This is crucial for Big Block Chevy engines, especially those with modifications, as it helps protect the crankshaft from harmful stress that can lead to failure. The viscous damper design is race-proven and requires no maintenance, making it a solid choice for durability and performance.

This damper features a black zinc corrosion-resistant finish and engraved timing marks for easy setup. It's SFI 18.1 certified, meeting stringent racing standards. With an 8-inch diameter and weighing 15.3 lbs, it's engineered for internally balanced Big Block Chevy engines with both a 3/16-inch and a 1/4-inch key slot. This part fits a wide range of classic Chevy vehicles, including models like the Camaro, Chevelle, and Impala from the late 60s and early 70s, offering improved timing and potentially unlocking lost torque and horsepower by reducing wear on critical engine components.
