Fits LS1 and LS2 engines in GM F-Body and V-Body chassis. The ATI Super Damper (MPN: ATI917276) is a high-performance harmonic balancer engineered to eliminate damaging torsional crankshaft vibrations. Unlike standard OEM balancers, this unit provides superior protection for your rotating assembly across the entire RPM range, making it essential for high-performance street and track applications.

This specific model features a 6.78-inch diameter with a 10% underdrive for both the 6-rib main serpentine belt and the 4-rib A/C belt. By slowing down the engine accessories, it reduces parasitic drag to free up horsepower. The lightweight aluminum outer shell reduces rotational mass, while the internal 3-ring elastomer design provides precision damping that far exceeds stock single-ring capabilities.
