V10 FSI Lightweight Crank Pulley

Introducing the JHM V10 FSI Lightweight Crank Pulley, specifically engineered for the C6-S6 and D3-S8 vehicles featuring the V10 FSI engine. This American-made component is precisely counterbalanced to ensure seamless engine operation while significantly reducing rotating mass. By shedding approximately 8.8 lbs from the OEM pulley's 10.4 lbs weight, this modification contributes to unlocking the power potential of your naturally aspirated V10 FSI engine, though it is not a drastic horsepower increase on its own. The pulley is anodized in black to better blend with the factory aesthetic. Installation notes advise replacing drive or alternator belts concurrently and ensuring the new belt is tensioned at least as tightly as the stock belt to prevent slippage and squealing. One bolt hole on the OEM pulley contains a dowel that must be transferred to the JHM pulley, ensuring correct one-way installation. All bolts should be torqued to 20 ft lbs in a star pattern, with the recommendation to use Loctite.
