ATI Performance Crankshaft Damper for Dodge 5.7L & 6.4L Hemi Trucks

Enhance the performance and durability of your Dodge truck's 5.7L or 6.4L Hemi engine with the ATI 918454 crankshaft damper. Designed for 2009 and newer models, this damper features a 7.074-inch diameter and is constructed from lightweight, high-strength aluminum. It includes a 6-rib groove for accessory drive and a 15% Underdrive (UD) pulley, which can help reduce parasitic drag on the engine. The unique 2-ring design ensures superior vibration dampening and reliability for demanding applications.

Key Features for Hemi Trucks:

  • Diameter: 7.074 inches
  • Material: Premium Aluminum construction
  • Grooves: Single 6-Rib pulley for accessory drive
  • Vehicle Fitment: Specifically for Dodge trucks with 5.7L and 6.4L Hemi engines, model years 2009 and newer.
  • Underdrive: 15% Underdrive (UD) pulley to reduce accessory drag.
  • Design: 2-Ring construction for enhanced dampening.

Benefits of the ATI 918454 Damper:

The ATI 918454 damper is essential for controlling torsional vibrations inherent in Hemi engines, especially under performance conditions. By effectively absorbing these harmonics, it protects the crankshaft from stress and potential damage, leading to increased engine longevity. The underdrive pulley can also contribute to slight horsepower gains by reducing the load on the engine from accessories like the alternator and water pump. Its robust construction and precise engineering ensure a perfect fit and reliable operation, making it a critical upgrade for any performance-oriented Dodge truck owner.

Ensure your Hemi truck's engine is protected and performing optimally. Choose the ATI 918454 damper from GGCRACING.
