Fluidampr 6.2L / 6.5L GM Diesel 1982-1993 (Mechanical) Steel Externally Balanced Damper

When you're building a serious diesel engine, especially one that's going to see hard use, protecting the crankshaft from torsional vibration is key. What you get in this box is a Fluidampr harmonic balancer, built from high-grade steel and finished with a corrosion-resistant black zinc coating. This damper is designed to control harmful vibrations across the entire RPM range, which helps reduce wear on critical engine components and lowers the risk of crankshaft failure. It's a direct replacement for your stock externally balanced damper and features engraved timing marks for easier installation.

Fluidampr has been a trusted name in performance diesel for over 35 years, and this damper is SFI 18.1 certified, meaning it's race-proven and built to handle demanding conditions. Unlike some other dampers, this one requires no maintenance; its viscous design works automatically to absorb vibrations. By controlling these harmful oscillations, you can also expect to see some of the lost torque and horsepower unleashed, leading to a more responsive engine. This damper fits a wide range of GM trucks and SUVs from 1982-1993 with the 6.2L and 6.5L diesel engines, including popular models like the Chevrolet C20 Suburban and GMC K2500.

This damper is precision CNC machined and balanced right here in the USA. If you're looking to improve the longevity and performance of your GM diesel, this is a solid option that's built to last and requires zero upkeep.
