TriboDyn Tri-EX² 50W is a full synthetic heavy-duty gear oil engineered with patented ceramic coating technology — the first oil to receive a United States Functional Patent in over 30 years. This formulation combines advanced synthetic base stocks with a sulfur-phosphorus extreme pressure additive package and friction modifier. The proprietary ceramic technology actively seeks out areas of intense heat and friction to form a self-lubricating ceramic film that not only prevents wear but can help repair minor surface damage.
Meeting or exceeding API MT-1, Eaton PS-386 & PS-164 Rev 7, Navistar/International TMS 6816, Mack TO-A Plus, Meritor O-81, and ZF Freedomline specifications, Tri-EX² 50W delivers unmatched load-carrying capability and extended component life. With a pour point of -36°C for reliable cold starts and exceptional thermal stability for high-temperature protection, this gear oil is ideal for heavy-duty truck transmissions, differentials, and industrial gearboxes requiring a 50W viscosity.
Key Benefits:
- Patented ceramic coating technology that helps repair minor surface damage
- Full synthetic 50W for heavy-duty truck and industrial applications
- Excellent extreme pressure and load-carrying capability
- Strong thermal stability and cold-flow performance (-36°C pour point)
- Broad OEM approvals for heavy-duty truck transmissions and differentials
- Reduces wear and extends component life in demanding conditions
Recommended Applications: Ideal for heavy-duty truck transmissions, differentials, and industrial gearboxes requiring a 50W viscosity, especially in applications where maximum protection and potential surface repair benefits are desired.
