HKS 12999-AK007 GT Supercharger Pulley 8 Rib 120mm Universal

The HKS 12999-AK007 GT Supercharger Pulley is an engineered replacement pulley designed to work in conjunction with HKS GT Series centrifugal superchargers. This precision-machined pulley helps optimize boost levels and power delivery by controlling the drive ratio between the crankshaft and supercharger unit.

Key Features:

• 8-rib serpentine belt design for optimal grip and reduced belt slippage
• 120mm diameter provides balanced boost and power characteristics
• Durable black anodized finish for corrosion resistance
• Universal fitment for HKS GT Series supercharger systems
• Precision-machined construction ensures proper belt alignment and longevity

This supercharger pulley allows for stable torque delivery across the entire engine RPM range, promoting smooth and linear power increases from low to high RPM. The 8-rib configuration ensures maximum power transfer efficiency while minimizing the risk of belt slip under high boost conditions. Note that this pulley is sold separately and does not include the supercharger unit.
