What is Supercharger Traction Fluid?

Twin-screw and Roots-type superchargers like those used in HKS GT series kits use a pair of meshing rotors to compress intake air. These rotors spin at very high speeds — often several times engine RPM — and are driven by a belt connected to the engine's crankshaft. The rotors themselves do not contact each other (they are held in precise proximity by timing gears), but the timing gears, bearings, and other internal components require lubrication. Supercharger traction fluid is the specialized lubricant that fills the supercharger's internal cavity, lubricating these components under the high-speed, high-temperature conditions of supercharger operation. Unlike engine oil or gear oil, supercharger traction fluid is formulated specifically for the unique demands of supercharger internals — including the correct viscosity, thermal stability, and compatibility with the supercharger's seals and materials.

Why Proprietary HKS Fluid?

HKS specifies their proprietary Traction Fluid Type I for GT series supercharger kits because the fluid's formulation is matched to the specific materials, tolerances, and operating conditions of their supercharger units. Generic gear oils, transmission fluids, or aftermarket supercharger fluids may have incorrect viscosity, incompatible additive packages, or inadequate thermal stability for HKS GT supercharger operation. Using an incorrect fluid can result in accelerated wear of the supercharger's internal components, seal degradation, and ultimately supercharger failure. The cost of supercharger repair or replacement far exceeds the cost of using the correct HKS fluid — always use HKS-specified traction fluid for GT S/C maintenance.

Type I vs. Type II:

HKS offers GT supercharger traction fluid in multiple types (Type I, Type II, etc.) for different supercharger applications and specifications. Verify which type is specified for your specific HKS GT supercharger kit before ordering. The type designation reflects differences in fluid formulation appropriate for different supercharger designs or operating conditions within the HKS GT lineup. Using the wrong type can result in incorrect lubrication and potential supercharger damage. Consult your HKS GT supercharger kit documentation or contact HKS directly to confirm the correct fluid type for your application.

HKS GT Supercharger Series:

The HKS GT supercharger series is HKS's line of positive displacement supercharger kits for Japanese performance vehicles, providing forced induction with the immediate throttle response and linear power delivery characteristic of supercharging. Unlike turbochargers, which use exhaust gas energy to drive a compressor, superchargers are mechanically driven by the engine and provide boost from idle without turbo lag. HKS GT supercharger kits are engineered for specific vehicle applications and are known for their quality construction, reliable performance, and significant power gains over naturally aspirated configurations. Proper maintenance with the correct HKS traction fluid is essential for preserving the supercharger's performance and longevity.

Maintenance Interval:

HKS specifies fluid change intervals for GT series supercharger kits in the kit's documentation. Supercharger traction fluid degrades over time due to heat cycling, shear stress from the high-speed rotating components, and contamination. Following the specified change interval ensures the supercharger's internal components remain properly lubricated throughout their service life. Neglecting fluid changes can result in accelerated wear and premature supercharger failure. Refer to your HKS GT supercharger kit documentation for the specific fluid capacity and change interval for your application.

Why HKS?

HKS is one of Japan's most respected and longest-established performance parts manufacturers, with decades of motorsport and street performance heritage. Their GT supercharger series represents the pinnacle of their forced induction engineering, and their proprietary traction fluid is developed to the same exacting standards as the supercharger units themselves. HKS's commitment to quality and engineering excellence ensures their traction fluid provides the correct lubrication for reliable, long-term GT supercharger performance.

Perfect For:

• HKS GT series supercharger kit owners performing scheduled fluid maintenance
• GT2, GT3, and GT4 supercharger kit maintenance requiring Type I traction fluid
• HKS authorized dealers and installers stocking GT S/C maintenance fluids
• Anyone performing HKS GT supercharger service requiring the correct proprietary fluid

Perfect For: HKS GT series supercharger kit owners requiring Type I traction fluid for scheduled supercharger maintenance — the correct, proprietary HKS fluid for GT S/C longevity and performance.

Pro Tip: Keep a record of your supercharger fluid change dates and mileage — consistent maintenance with the correct HKS fluid is the single most important factor in maximizing your GT supercharger's service life and maintaining its performance output.
