ATI Super Damper – 7.48in Aluminum | 6-Groove | LS1/2/3/6/L76 | 1997–2013 Y-Body / SS / G8

Protect your LS engine’s crankshaft from torsional vibration with the ATI Super Damper — the gold standard in harmonic damper technology for high-performance and racing applications. Engineered specifically for LS1/2/3/6 and L76 engines in Y-Body (Corvette), SS (Camaro/Caprice), and Pontiac G8 platforms, this 7.48-inch aluminum damper features a 6-groove serpentine belt drive, 28-tooth 8mm HTD cam drive provision, and a 3-ring tunable design for precise vibration control across a wide RPM range.

Unlike rubber-bonded OEM dampers that degrade over time and lose effectiveness at high RPM, ATI’s Super Damper uses a precision-machined inertia ring and elastomer tuning rings that can be reconfigured as your engine build evolves — making it the preferred choice of professional engine builders and racers worldwide.
