The Fluidampr Steel Externally Balanced Damper fits the 2020-2026 Chevy Silverado 2500HD with the 6.6L Duramax and controls torsional vibration across the entire RPM range.

Install Difficulty: Professional Install Only
Crankshaft damper replacement requires a harmonic balancer puller, installer tool, and torque-to-yield bolt procedure; typically takes 2-3 hours with the front cover accessible.

Product Overview

This viscous-style damper replaces the factory harmonic balancer with CNC-machined high-grade steel components and a removable hard-coat anodized aluminum fan pulley.

Broad-RPM damping reduces wear on the crankshaft, timing gear, and front-end accessories -- critical protection for tuned or towing-heavy Duramax builds.

SFI 18.1 certified, corrosion-resistant black zinc finish, engraved timing mark, and made in USA.
