Chevrolet Silverado Crankshaft Damper - ATI - 7.425 - Steel - 6 Grv - Ext Bal - 3 Ring (2001-2005). Purpose-built for Duramax LB7 & LLY diesel trucks, this damper replaces the factory unit with ATI’s proven vibration-control design.

Engineered to manage torsional vibration, it helps protect the crankshaft, bearings, and belt-driven accessories in daily use or under added load. The 7.425-inch steel shell and 6-groove drive maintain OE belt alignment, while the external-balance configuration suits LB7/LLY requirements. Its three-ring layout is designed for diesel vibration characteristics, promoting smooth, consistent operation and long-term durability.
