ATI Performance Products ATI916153 Serpentine Supercharger Pulley 8-Groove 7.990 in. Steel

The ATI Performance Products ATI916153 is a precision-engineered serpentine supercharger pulley designed to enhance performance and reliability in supercharged engine systems. This pulley is an OEM-size replacement with a 7.990" outer diameter and features an 8-groove serpentine design, ensuring compatibility with the stock supercharger drive system.

Key Features:

• ATI's proprietary Superior Sprag Technology allows the supercharger to "freewheel" when the throttle is closed, eliminating blower belt failure by releasing the supercharger when it spins faster than engine RPM
• Improved boost retention during gear changes as the supercharger maintains boost longer and does not ramp down as quickly as the engine
• Reduced supercharger wear through the freewheel mechanism that prevents the gear drive from meshing in the opposite direction during spin-down
• Precision-machined from high-grade steel with black finish for strength and resistance to wear under high-RPM conditions
• Direct bolt-on replacement for OEM supercharger pulley

This pulley is ideal for both street and competition applications, offering durability and performance enhancements without altering stock boost levels. Hardware is not included and sold individually.
