Triax Haldex Clutch Fluid Full-Synthetic 1 Quart — Low-Viscosity, Gen 1–5 Compatible

TRIAX HCF Professional is a full-synthetic, low-viscosity hydraulic coupling fluid specifically formulated for Haldex electronically controlled wet multi-plate clutches across all five Haldex generations.

When a transverse all-wheel-drive vehicle relies on a Haldex coupling, the fluid inside the coupling controls how smoothly and quickly the system transfers torque. TRIAX HCF Professional uses a premium synthetic base and a tailored friction modifier package to reproduce the controlled grip, pump response, and seal compatibility modern Haldex systems require. The result is consistent engagement behavior, reduced shudder, and extended fluid life compared with conventional oils not designed for wet clutches.

How does TRIAX HCF stop AWD shudder and stick-slip?

The fluid includes a balanced friction modifier formulation designed to control the friction characteristics of wet clutch plates during engagement. That balance prevents abrupt grab or chattering while still allowing the necessary torque transfer across the coupling.

• Precision friction modifiers tuned for multi-plate clutches
• Low-viscosity synthetic base to maintain stable engagement timing
• Ashless additives that protect surfaces without depositing residues

Will this product work in my Haldex generation and vehicle make?

TRIAX HCF Professional is engineered to meet specifications for all five Haldex generations, including VW/Audi G 060 175 and G 055 175 A2 equivalence. It suits many transverse AWD systems that call for a Haldex-type coupling fluid.

• Compatible with Haldex Gen 1–5 applications
• Fits systems like Volkswagen 4Motion and Audi transverse Quattro
• Also suitable for Volvo XC AWD, Ford Kuga/Focus AWD, Land Rover Freelander 2, and similar models

How long will the fluid retain performance and protect seals?

The synthetic formulation offers strong shear stability so viscosity remains within specification through prolonged service, helping preserve pump response and engagement characteristics. The fluid is compatible with common seal materials used in Haldex units to reduce the risk of swelling, shrinkage, or leaks.

• High shear stability for long-term viscosity control
• Compatible with NBR and FKM seals to prevent seal damage
• Ashless wet-clutch chemistry reduces harmful deposits on friction surfaces

What service practices should I follow when using this fluid?

Replace the coupling fluid at intervals recommended by your vehicle maker—many manufacturers suggest around 30,000–40,000 miles—and change the filter when applicable (Gen 4 and later typically have a serviceable filter). Always follow the vehicle’s service manual for safe drainage, refill volume, and bleeding procedures.

• Observe manufacturer-recommended service intervals (commonly 30k–40k miles)
• Replace the Haldex filter on Gen 4+ units during service
• Use correct fill volumes and bleeding steps from the owner or repair manual

Who is this for? Drivers and technicians who maintain transverse AWD systems with Haldex couplings — including VW/Audi owners, independent shops, and DIYers familiar with fluid-service procedures — will find TRIAX HCF Professional useful when they need a single fluid solution that covers multiple Haldex generations. It’s intended for units that explicitly call for a Haldex-type hydraulic coupling fluid; always confirm compatibility with your vehicle’s specification before use.
