ATI Damper - 6.78in - AL - 6/4 Grv - 10 Per UD - LS1/2/3/6 - 97-13 Y Body - 10 Per UD A/C - 3 Ring

If you're building a high-performance LS engine, especially one that will see track time or aggressive street use, controlling crankshaft harmonics is absolutely critical. This ATI Damper, part number 917278, is designed specifically for LS1, LS2, LS3, and LS6 engines found in 1997-2013 Y-Body vehicles. It's a well-built component that helps prevent premature wear and potential failure of your crankshaft and other rotating assembly components by absorbing damaging vibrations.

This damper features a 6.78-inch diameter and is constructed from lightweight aluminum. It incorporates ATI's signature 3-ring design with 6 outer grooves and 4 inner grooves for serpentine belt drive systems, including provisions for A/C. The 10-rib serpentine pulley design ensures a solid grip for accessories. ATI is well-known for their robust damper technology, and this unit is built to handle the increased stress and higher RPMs common in modified LS applications. Proper harmonic dampening is essential for engine longevity and consistent performance, especially when you've invested heavily in other engine upgrades.

When installing this damper, ensure you have the correct tools to remove the old unit and properly seat the new one. Refer to the manufacturer's installation instructions for specific details regarding torque specifications and any required alignment procedures. This damper is a key component for any serious LS engine build where reliability and performance are paramount.
