ATI Damper - 6.78in - Alum - 6 Grv - Dodge - 2011+ - VVT - 6 Percent OD - 5.7L & 6.4L Hemi - 3 Ring

This ATI crankshaft damper is built with a 6-groove pulley system and a 6 percent overdrive design, measuring 6.78 inches in diameter. It's specifically made for Dodge vehicles equipped with 5.7L and 6.4L Hemi VVT engines from 2011 and newer. The damper plays a crucial role in managing torsional vibrations from the crankshaft, which helps maintain accurate engine timing and protects the engine from damage caused by these vibrations. Its aluminum construction keeps the weight down while providing a solid foundation for the dampening rings.

The 3-ring design within this damper offers enhanced vibration control compared to single-ring units. This advanced dampening capability is important for engines that see regular use or are modified, as it helps to smooth out the power delivery and reduce stress on critical engine components like the crankshaft and bearings. The 6 percent overdrive means the accessory drive system will spin slightly faster than stock, which can be beneficial for cooling fans or alternators that need to move more air or generate more current at lower engine speeds.

When installing this damper, ensure you have the correct tools to remove the old unit and properly seat the new one. It's a key component for maintaining the health and performance of your Hemi engine, especially if you're looking for improved reliability under various operating conditions.
