ATI Shell Assy - 8.90 - AL - 10 Grv - 2015+ Dodge 6.2L- 10 Per OD SC Drive - OEM Acc Drive - 3 Ring

This is the ATI 8.90 inch aluminum crankshaft damper, part number 918485S, specifically made for 2015 and newer Dodge vehicles with the 6.2L supercharged engine, like the Hellcat, Redeye, and Demon. It's designed to work with the OEM accessory drive system and features a 3-ring design with 10 grooves for the supercharger drive. A crankshaft damper, also known as a harmonic balancer, is crucial for absorbing torsional vibrations from the engine's crankshaft. Without it, these vibrations can cause premature wear and even damage to the crankshaft and other engine components over time. This ATI damper is a well-built unit designed to handle the stresses of high-performance, supercharged applications.

The damper itself is constructed from aluminum, which helps keep overall weight down compared to cast iron alternatives. The 8.90-inch diameter and the 10-groove pulley system are engineered to work seamlessly with the factory accessory drive setup, ensuring proper belt alignment and tension for the supercharger and other accessories. The 3-ring design offers a robust mounting surface and contributes to the damper's ability to effectively dissipate harmful engine harmonics. This part is a popular choice for enthusiasts looking to maintain or upgrade the critical crankshaft dampening system on their powerful Dodge muscle car.

When installing a new crankshaft damper, it's important to ensure the crankshaft snout is clean and free of debris. Refer to the manufacturer's installation instructions for specific details regarding proper fitment and any required tools. This damper is designed as a direct replacement for the OEM unit, making the installation process straightforward for those familiar with engine work.
