## Features

- INTEGRATED FRICTION MODIFIER - NO SEPARATE ADDITIVE NEEDED – This professional-grade full synthetic gear oil comes ready for your limited slip or positraction differential. The precise friction modifier is expertly blended in, eliminating the need for a separate bottle and the guesswork of mixing.
- ADVANCED METAL-BONDING TECHNOLOGY FOR STARTUP PROTECTION – Our formula includes additives that bond a protective oil layer to gear and bearing surfaces. This ensures critical lubrication is present during dry starts and high-load conditions, preventing initial wear before full oil circulation.
- MAXIMUM FILM STRENGTH & EXTREME PRESSURE PROTECTION – Engineered with an advanced additive package to provide exceptional film strength—the most critical factor in wear prevention. Maintains a protective barrier between metal components under shock loads, high torque, and extreme temperatures.
- PREMIUM FULL SYNTHETIC BASE FOR SUPERIOR PERFORMANCE – Formulated with high-stability, shear-resistant synthetic base oils for outstanding thermal and oxidative stability. Reduces deposit formation and provides excellent high-temperature protection with superior low-temperature flow.
- MEETS & EXCEEDS KEY INDUSTRY & OEM SPECIFICATIONS – Qualified for API GL-5, API MT-1, and MIL-PRF-2105E. Trusted for use in differentials, manual transmissions, and transfer cases in cars, trucks, and heavy-duty applications requiring these demanding specifications.
- COMPATIBLE & VERSATILE UNIVERSAL GEAR OIL – Designed for use in Limited Slip/Positraction Differentials, conventional differentials, manual transmissions, and transfer cases. Fully compatible with other synthetic and conventional gear oils for easy service.
- REDUCES FRICTION, WEAR, AND OPERATING TEMPERATURES – Our TRI-EX technology is engineered to treat the metal surface, not just lubricate it. The result is smoother operation, extended component life, and reduced maintenance costs over the life of your vehicle.
- Low-Temperature Fluidity Down to -50°F: Flows easily in cold weather for quick startups and protection, making it the go-to 75W90W synthetic gear lube for DIYers in harsh climates.
