ATI Performance Products ATI916244-15 Supercharger Pulley 15% Underdriven 11-Groove Serpentine 2019+ Corvette ZR1 LT5

The ATI Performance Products ATI916244-15 is a precision-machined supercharger pulley designed specifically for 2019 and newer Chevrolet Corvette ZR1 models equipped with the LT5 supercharged engine. This 15% underdriven pulley reduces supercharger speed compared to the OEM pulley, resulting in lower boost pressure for applications requiring reduced stress on engine components or alternative tuning strategies.

Key Features:

• 15% underdriven diameter for reduced boost and supercharger speed
• 11-groove serpentine belt design for positive engagement
• Precision CNC-machined from high-quality materials for durability
• Direct replacement for OEM supercharger pulley
• Designed specifically for LT5 supercharged 6.2L V8 engine
• Engineered by ATI Performance Products with over 50 years of racing experience

This pulley is ideal for builds where lower boost levels are desired, such as street-driven vehicles requiring more conservative tuning, engines with reliability concerns, or setups using premium pump fuel without aggressive tuning. Professional installation and proper belt tensioning are recommended for optimal performance and longevity.
