TriboDyn Tri-EX² 250W is an ultra-heavy-duty full synthetic gear oil engineered with patented ceramic coating technology — the first oil to receive a United States Functional Patent in over 30 years. This extreme SAE 250W (ISO 460 equivalent) formulation is designed for the most demanding applications where conventional gear oils simply cannot keep up.
The proprietary ceramic technology actively forms a self-lubricating film in areas of high heat and extreme pressure, minimizing metal-to-metal contact and even helping to repair damaged surfaces. Independent university testing showed TriboDyn’s ceramic technology delivered film strength nearly double the next best oil and scar size almost 5 times smaller than competitors.
Meeting or exceeding API GL-5, API MT-1, and AGMA requirements, this 250W gear oil is the ultimate choice for racing, rock crawling, heavy-duty industrial, and severe off-road applications.
Key Benefits:
- Patented ceramic coating technology for superior film strength
- Ultra-heavy SAE 250W (ISO 460) for extreme load applications
- Nearly double the film strength of competing oils (university tested)
- Helps minimize wear and repair damaged surfaces
- Excellent extreme pressure and shock load protection
- Reduces operating temperatures under severe conditions
Recommended Applications: Ideal for heavy-duty differentials, manual transmissions, transfer cases, power dividers, and oil-lubricated wheel bearings in racing, rock crawling, heavy industrial equipment, and severe off-road applications where maximum protection is required.
