HKS 12002-AK005 GTS4015HP GT Supercharger Universal Kit

The HKS 12002-AK005 is a universal GT Supercharger assembly built around the GTS4015HP centrifugal supercharger unit. Designed for vehicles not covered by an HKS vehicle-specific kit, this universal kit delivers a targeted power output range of 100–150 PS and is engineered around HKS's patented Torque Response Traction Drive system for smooth, linear power delivery throughout the entire RPM range.

Key Features:

• Centrifugal supercharger design — compact and lightweight compared to traditional roots-type or twin-screw blowers
• Traction Drive system — significantly reduces mechanical noise compared to gear-driven supercharger designs
• 9.875:1 drive unit ratio — allows for a higher overdrive ratio and a more compact compressor unit
• Max impeller speed: 110,000 RPM
• Max pressure ratio: 3.0
• Max airflow: 0.17 kg/s
• Power range: 100–150 PS (approximately 99–148 hp)
• Unit weight: 3.5 kg (approx. 7.7 lbs)
• Torque Reaction system — applies pressure proportional to transfer torque for improved durability and efficiency under varying load conditions
• Self-contained traction oil system for reliable internal lubrication
• Note: A pulley is required for installation and is sold separately

What's Included:

• GTS4015HP Supercharger main unit
• Traction Fluid I – 800ml
• Oil cooler
• Hose assemblies for traction fluid (×2)
• Oil tank
• Miscellaneous hardware

This universal kit is intended for custom installations on vehicles not supported by an HKS vehicle-specific supercharger kit. Additional vehicle-specific support parts and brackets may be required and are sold separately. Professional installation by a qualified performance shop is strongly recommended. CARB compliance status should be verified for your specific application prior to purchase.
