What is the main benefit of installing this ATI crankshaft damper?

This damper helps manage torsional vibrations from the crankshaft, which is important for engine longevity. It also features a 15% underdrive pulley setup that can reduce accessory drag and potentially free up a small amount of horsepower.

What does the '15 Per UD' specification mean?

'15 Per UD' refers to a 15% underdrive pulley. This means the accessories driven by the damper, like the alternator and water pump, will spin 15% slower than they would with a stock damper. This reduces the load on the engine.

What material is this crankshaft damper made from?

This crankshaft damper is constructed from aluminum. This material choice helps to keep the component strong while also minimizing added weight to the engine assembly.

Product Details

This ATI crankshaft damper is designed for 2009 and 2010 Dodge vehicles equipped with the 5.7L Hemi VVT engine. It's a well-built component that helps manage torsional vibrations from the crankshaft, which is crucial for engine longevity and smooth operation. The damper itself is made from aluminum and features a 5.67-inch diameter with six grooves for accessory drive belts, specifically set up for 15% underdrive.

ATI is known for making solid performance parts, and this damper is no exception. The aluminum construction keeps the weight down while providing the necessary strength to handle the stresses of engine operation. The 15% underdrive pulley setup means your accessories like the alternator and water pump will spin slightly slower, reducing parasitic drag on the engine and potentially freeing up a small amount of horsepower. This is a popular choice for Hemi owners looking to improve their engine's performance and reliability.

When installing this damper, ensure you have the proper tools to remove the old one and install the new one securely. It's a direct replacement for the stock unit, but proper alignment and torquing are important for optimal performance and to prevent damage.
