Adds More Durability to Your GM 6.6L Duramax

If you're adding power to your L5P Duramax or just want better engine protection, upgrading to the Fluidampr Performance Damper is a smart move. This isn’t your average stock balancer—it’s engineered to handle the demands of high-torque diesel engines like the 6.6L Duramax. Whether you’re towing heavy, adding horsepower, or running a performance tune, this damper is built to keep harmful vibrations in check and preserve the life of your internal engine components. The Fluidampr uses a viscous silicone design, meaning it adapts in real-time to control crankshaft torsional vibrations across a broad RPM range. That translates into smoother operation, better power delivery, and less stress on bearings, the crankshaft, and other rotating parts. No tuning or maintenance is needed—it’s a direct bolt-on solution designed for serious reliability.

Built to Last

Built in the USA from high-grade CNC-machined steel, it’s finished in a corrosion-resistant black zinc coating and SFI 18.1 certified for safety. If you've upgraded injectors, turbo components, or the rotating assembly, this damper helps you get the most out of your setup while protecting your investment. Whether you’re daily driving, hauling, or hitting the dyno, the Fluidampr Performance Damper delivers the performance and peace of mind your L5P deserves.
