Key Features:

• Complete dual pulley kit with matched belt included
• 187mm bolt-on crank pulley that retains factory harmonic balancer
• 57.75mm press-on supercharger drive pulley for precision fit

• Anodized and E-coated in factory black finish for durability and OEM appearance
• Engineered to maintain proper engine balance while maximizing boost pressure

This pulley upgrade is essential for enthusiasts seeking significant power increases from their 3.0 TFSI platform. The smaller supercharger pulley increases the speed ratio, forcing more air into the engine and creating higher boost levels. When combined with APR ECU tuning, this modification unlocks substantial performance gains throughout the powerband. Professional installation and appropriate engine tuning are required to achieve optimal results and ensure safe operation.
