Fluidampr Chevy 454-502 CID-V8 w/ one 3/16 and one 1/4 key slot Steel Externally Balanced Damper

Starting with the dual keyway design, featuring one 3/16-inch and one 1/4-inch slot, this Fluidampr harmonic balancer is built for serious performance applications. Modifications to your engine can often compromise the effectiveness of a stock harmonic balancer, leading to increased wear on critical components like the crankshaft. Installing a Fluidampr early in your build, especially if you're planning on performance upgrades, is a smart move for long-term durability.

This damper uses a superior viscous design to control harmful torsional vibrations throughout the entire RPM range, not just at a specific speed. This broad-spectrum protection helps reduce wear on your engine's internal parts and significantly lowers the risk of crankshaft failure. You might also notice improved timing accuracy and a bit of unleashed torque and horsepower that was previously lost to these vibrations. It's precision CNC machined from high-grade steel, features a corrosion-resistant black zinc finish with engraved timing marks, and requires no maintenance. It's SFI 18.1 certified, race-proven for over 35 years, and trusted by leading engine builders worldwide.

This damper fits a wide range of Chevrolet big block V8 engines, including those found in vehicles like the 1970-1975 Chevrolet Impala, 1970-1974 Chevrolet Corvette, and 1992-1999 Chevrolet K2500 Suburban. It's designed for externally balanced engines and is made in the USA.
