About This

• U.S. PATENTED CERAMIC COATING TECHNOLOGY – GOES BEYOND CONVENTIONAL LUBRICATION Unlike standard gear oils that simply coat surfaces, our patented formula is engineered to be attracted to areas of intense heat and friction. Under pressure, it forms a solid, self-lubricating ceramic film on gear and bearing surfaces. This revolutionary technology actively fills in microscopic grooves and surface imperfections, creating a smoother finish that reduces wear, lowers operating temperatures, and can extend component life compared to conventional oils.
• EXCEEDS THE TOUGHEST GLOBAL PERFORMANCE SPECIFICATIONS – INDEPENDENTLY VERIFIED Don't just take our word for it. TriboDyn Tri-Ex² is rigorously formulated to meet or exceed a demanding list of industry and military standards, including API GL-5, API MT-1, and MIL-PRF-2105E. This industry-standard validation proves it provides superior extreme pressure protection, shock load capacity, and anti-wear performance for your differential, manual transmission, and transfer case, ensuring peace of mind in the most severe operating conditions.
• ENGINEERED FOR EXTREME PRESSURE & SHOCK LOADS – PROTECTS YOUR INVESTMENT Whether you're towing a heavy trailer, on the racetrack, or managing a fleet of commercial trucks, sudden shock loads are the primary cause of gear failure. Our advanced sulfur-phosphorus extreme pressure (EP) additive package is specifically designed to prevent metal-to-metal contact under high torque and impact loads, effectively guarding against pitting, spalling, and catastrophic gear tooth failure.
• PREMIUM FULL SYNTHETIC 75W-90 BASE OIL – MAXIMUM PERFORMANCE & STABILITY The foundation of any great lubricant is its base oil. We use only the highest quality Group V full synthetic base stocks, which provide exceptional film strength, superior thermal and oxidative stability, and excellent flow at low temperatures. This means consistent protection from cold start-ups to high-temperature operation and resistance to sludge and varnish formation for extended drain intervals.
• SIGNIFICANTLY REDUCES OPERATING TEMPERATURES & FRICTION High heat is the enemy of any gearbox, breaking down oil and accelerating wear. The combination of our premium synthetic base oil and ceramic coating technology dramatically reduces fluid friction and operating temperatures. A cooler-running differential or transmission directly translates to more horsepower at the wheels, improved fuel efficiency, and significantly longer service life for seals, bearings, and gears.
• COMPREHENSIVE ANTI-FOAM, ANTI-RUST & ANTI-CORROSION PROTECTION Protection is more than just wear prevention. Our multi-faceted additive system robustly resists foam formation, which can lead to pump cavitation and oil starvation. It also creates a powerful protective barrier on internal metal surfaces to prevent rust and corrosion, even in high-humidity environments or during long storage periods, ensuring your equipment is ready when you are.
• SMOOTHS AND QUIETS GEAR OPERATION – A TANGIBLE DIFFERENCE YOU CAN FEEL Experience a noticeably smoother and quieter drivetrain. By filling in surface imperfections and maintaining a consistent protective film, TriboDyn Tri-Ex² minimizes gear whine, reduces shift effort in manual transmissions, and dampens driveline noise. This provides a premium driving experience and serves as immediate, audible proof of the advanced protection at work inside your components.
• TRUSTED BY PERFORMANCE ENTHUSIASTS & COST-CONSCIOUS FLEET MANAGERS TriboDyn is the chosen brand for those who cannot afford failure. Racers trust it for its unmatched shock load protection under extreme stress. Fleet managers rely on it to maximize vehicle uptime and reduce costly repairs across their entire operation. This dual endorsement underscores its unique ability to deliver both peak performance and unparalleled reliability.
• PRECISION-ENGINEERED IN THE USA – BACKED BY ISO 9001 CERTIFIED MANUFACTURING Every bottle of TriboDyn is formulated and manufactured in our state-of-the-art U.S. facilities, which are certified to the rigorous ISO 9001 international standard for quality management. This certification is your assurance of unparalleled consistency, traceability, and quality control in every batch, guaranteeing that our gear oil delivers the peak performance and protection we promise.
• IMPORTANT WARNING – CRITICAL FOR APPLICATION COMPATIBILITY DO NOT USE in wet clutch applications (common in many motorcycles and some AWD systems) or in limited-slip differentials that require a specific friction modifier. Using this oil in these applications can cause clutch slippage or differential chatter. For limited-slip units, use TriboDyn 75W90 Full Synthetic Limited Slip Gear Oil. Always verify your vehicle's requirements to ensure proper compatibility and performance.
