Kraftwerks 159-99-7507 Supercharger Pulley - 75mm 7-Rib

The Kraftwerks 159-99-7507 is a precision-engineered 75mm supercharger pulley designed for use with Kraftwerks Rotrex supercharger systems. This performance pulley is manufactured from black anodized billet aluminum for exceptional strength, durability, and heat dissipation while maintaining a lightweight profile.

Key Features:

• 75mm diameter for precise boost control and performance tuning
• 7-rib serpentine belt design for maximum grip and power transfer
• Black anodized billet aluminum construction resists corrosion and wear
• Direct replacement for Kraftwerks supercharger systems
• Allows boost adjustment by changing pulley size
• Precision-machined to OEM specifications

Changing the supercharger pulley diameter is one of the most effective methods to adjust boost pressure and performance characteristics in your Kraftwerks supercharger system. Smaller pulleys increase supercharger speed and boost output, while larger pulleys reduce boost for a more conservative tune. This 75mm pulley represents the smallest diameter option in the Kraftwerks lineup, providing maximum boost potential for experienced tuners seeking aggressive power gains.

Important: Always use genuine Kraftwerks replacement parts to maintain system reliability and warranty coverage. Pulley changes should be accompanied by proper tuning and may require a different serpentine belt length.
