Fluidampr Ford 302 351 / 400 Internal balance (replaces 28 oz in) Steel Internally Balanced Damper

When you're building or modifying a Ford Small Block engine, especially those with 302, 351, or 400 cubic inches, protecting the crankshaft from torsional vibrations is key. This Fluidampr harmonic balancer is designed to replace the stock 28 oz externally balanced unit with a superior internally balanced design. What you get in this package is the Fluidampr harmonic balancer itself, precision CNC machined from high-grade steel with a corrosion-resistant black zinc finish and engraved timing marks. It's built to control harmful vibrations across the entire RPM range, which helps reduce wear on critical engine components like the crankshaft and bearings, ultimately lowering the risk of crankshaft failure. This can also lead to improved timing accuracy and potentially unleash lost torque and horsepower.

It's SFI 18.1 certified, meaning it meets stringent safety standards for racing applications. This damper is trusted by leading engine builders worldwide for its superior durability and effectiveness in keeping engines running smoothly and reliably, even under demanding conditions. It's a solid investment in the longevity and performance of your Ford engine.

This harmonic balancer is designed to fit a wide range of Ford vehicles, including many trucks and classic models from the 1960s through the mid-1980s, such as the Ford F-150, Bronco, and Gran Torino. It's a direct replacement for the stock unit, making installation straightforward for those familiar with engine work. Ensure you're using the correct internally balanced damper for your specific engine build to get the most benefit.
