ATI Damper - 7.074in - Alum - 7 Grv - Nissan V6 VQ35Hr VQ37VHR - 15 Percent Underdrive

This ATI crankshaft damper measures 7.074 inches in diameter and is constructed from aluminum. It's designed with 7 grooves for accessory belts and offers a 15 percent underdrive for Nissan V6 engines using the VQ35HR and VQ37VHR platforms. This damper helps manage torsional vibrations from the crankshaft, which is crucial for engine longevity and smooth operation, especially in performance applications.

The aluminum construction makes this damper lighter than a steel equivalent, which can offer a slight advantage in reducing rotational mass. The 15 percent underdrive means that the accessories driven by the crankshaft pulley (like the alternator, power steering pump, and water pump) will spin 15 percent slower than they would with a stock damper. This can reduce drag on the engine, potentially freeing up a small amount of horsepower and reducing wear on the accessory components. The 7-groove design ensures proper belt engagement for all necessary accessories.

When installing this damper, ensure you have the correct tools to remove the old unit and properly seat the new one. It's a direct replacement for the factory damper, but proper alignment and securing are key to its function and the health of your engine.
