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.

Why TriboDyn TRI-EX2 80W-250 Outperforms Other heavy duty Gear Oils
Extreme Pressure & Shock Load Protection
Heavy-duty gearboxes and differentials face constant high torque and sudden shock loads. TRI-EX2 80W-250 delivers superior extreme pressure protection, preventing metal-to-metal contact and dramatically reducing wear in the most demanding applications.
Extreme Film Strength & Wear Protection
Standard gear oils break down under heavy loads. TRI-EX2 80W-250 provides exceptional film strength and wear protection, keeping gears and bearings protected longer and reducing metal loss even in high-torque applications.
Patented Ceramic Coating Technology
Varnish buildup is a leading cause of inefficiency and downtime in rotary screw compressors. Tri-Guard 4046’s advanced PAO base and Tri-Guard™ technology provide outstanding resistance to varnish formation, keeping your airend and internals clean far longer than standard oils.
Quieter Operation & Extended Component Life
The combination of high film strength full synthetic oil and patented ceramic coating reduces friction and noise while extending gear and bearing life. TRI-EX2 80W-250 delivers smoother shifting, quieter operation, and significantly longer service intervals than standard gear oils.

Frequently Asked Questions
It meets or exceeds API GL-5, API MT-1, Eaton PS-386, Mack GO-J/GO-H, Meritor O-81, ZF Freedomline, and many other heavy-duty OEM requirements. It is fully compatible with most synthetic and conventional gear oils.
TriboDyn oils are developed by world-renowned Tribologists with decades of experience engineering high-performance lubricants for aerospace, heavy industry, and professional racing applications. This deep technical expertise ensures every formulation, including TRI-EX2 80W-250, delivers professional-grade performance and reliability you can trust in your heavy-duty equipment.
TRI-EX2 80W-250 is a premium full synthetic gear oil with the highest level of patented ceramic coating technology and high moly content. It forms a durable self-lubricating ceramic film under extreme pressure and heat, providing superior protection where standard gear oils fail.
The highest level of patented ceramic coating actively seeks out areas of heat and pressure to form a protective film that reduces friction, prevents metal-to-metal contact, quiets operation, and can help repair minor wear — delivering longer component life than standard gear oils.
It is engineered for heavy-duty differentials, manual transmissions, transfer cases, worm gears, power dividers, and oil-lubricated wheel bearings in trucks, construction equipment, mining, agriculture, and severe-service applications that require API GL-5 / MT-1 performance.
Yes. It delivers superior film strength and extreme pressure protection (800+ kg EP Weld Load), making it ideal for high-torque, shock-loaded gearboxes and differentials that experience heavy loads and sudden impacts.
