ATI Performance Products ATI917369 Super Damper 7.425" 6-Groove for 2006-2010 Duramax LBZ/LMM Diesel

The ATI Performance Products ATI917369 Super Damper is a high-performance harmonic balancer designed specifically for 2006-2010 GM Duramax LBZ and LMM diesel engines with external balance. This precision-engineered damper features a 7.425-inch steel construction with a 6-groove serpentine pulley configuration to accommodate factory accessory drives.

Key Features:

• 7.425-inch outer diameter steel construction for maximum durability
• 6-groove serpentine belt configuration for proper accessory drive engagement
• External balance design specifically engineered for LBZ and LMM Duramax applications
• SFI 18.1 certified for competition use and safety compliance
• Elastomer-free design eliminates the risk of damper deterioration and failure
• Improves engine protection by controlling destructive crankshaft torsional vibrations
• Ideal for performance diesel builds, towing applications, and high-output engines

ATI Super Dampers utilize a unique viscous fluid dampening system that provides superior harmonic control across the entire RPM range compared to conventional rubber-style dampers. This advanced design protects critical engine components including main bearings, crankshaft, and valve train from damaging resonance frequencies, making it an essential upgrade for modified or high-performance Duramax diesel engines.
