TRIAX HCF Professional Haldex Clutch Coupling Fluid

TRIAX HCF Professional is a fully synthetic, low-viscosity hydraulic coupling fluid engineered for Haldex electronically controlled wet multi-plate clutch systems used in transverse all-wheel-drive vehicles. Formulated with a precision-balanced friction modifier package on a premium synthetic base oil to deliver the smooth, shudder-free engagement and long-term thermal stability that modern AWD couplings require.

• ONE FLUID COMPATIBLE WITH ALL FIVE HALDEX GENERATIONS: Fully synthetic Haldex coupling fluid engineered to meet VW/Audi G 060 175 and G 055 175 A2, covering Haldex Gen 1 through 5. One bottle ends the guesswork of matching fluid to generation. 
• ELIMINATES AWD SHUDDER & STICK-SLIP: A precision-balanced friction modifier package delivers smooth, shudder-free clutch engagement, so your all-wheel-drive system grips cleanly and quietly instead of grabbing or chattering on turns. 
• CONSISTENT ENGAGEMENT, MILE AFTER MILE: Outstanding shear stability holds viscosity in spec to maintain pump response and engagement timing, so AWD performance feels the same at 40,000 miles as it did on day one 
• SEAL-SAFE & LEAK-RESISTANT: Fully compatible with NBR and FKM seals to prevent swelling, shrinkage, and leaks, while ashless wet-clutch additives safeguard friction surfaces without harmful deposits.
• FITS A WIDE RANGE OF TRANSVERSE AWD: Compatible with Volkswagen 4Motion, Audi Quattro (transverse), Volvo AWD XC, Ford Kuga/Focus AWD, Land Rover Freelander 2, and other systems calling for a Haldex-type fluid. Replace per your manufacturer's schedule (typically 30,000–40,000 miles); replace the Haldex filter on Gen 4 and later units.
