TriboDyn TRI-EX 75W-140 Full Synthetic Gear Oil with Built-in Friction Modifier for Limited Slip Differentials, API GL-5 Compatible - Made in USA (3 Quart Pack, 75W-140)

ELIMINATES NEED FOR SEPARATE ADDITIVE: Professionally formulated with an integrated, high-performance friction modifier. This 75W-140 limited slip gear oil is ready to use—no separate "limited slip additive" bottle required for smooth, quiet differential operation. CRITICAL FOR HEAVY-DUTY & HIGH-HEAT APPLICATIONS: The 75/140 viscosity rating provides the robust film strength demanded by severe-duty pickups, towing rigs, and vehicles operating in extreme ambient temperatures where thinner oils may fail. MEETS WSL-M2C192-A & OTHER KEY SPECS: Engineered to meet stringent OEM requirements, including specification WSL-M2C192-A, API GL-5, API MT-1, and MIL-PRF-2105E for guaranteed compatibility and protection. STOP LIMITED SLIP DIFFERENTIAL CHATTER: Our balanced friction modifier package ensures clutch-type LSD and Positraction units engage smoothly, eliminating the annoying chatter and binding associated with worn or incorrect fluids. FULL SYNTHETIC FORMULATION FOR EXTREME DUTY: Advanced synthetic base stocks offer superior thermal stability and oxidation resistance compared to conventional gear oils, drastically reducing wear and sludge formation under heavy loads. DESIGNED FOR MAXIMUM TORQUE & SHOCK LOADS: This SAE 140 gear oil is the go-to choice for high-horsepower performance vehicles, modified rigs, and hard-launch applications where shock loads can decimate inferior lubricants. MAXIMUM METAL ADHESION & FILM STRENGTH: Our 75W-140 formulation is engineered with a tenacious cling to metal surfaces, creating an exceptionally durable lubricating film that resists being squeezed out under extreme pressure, ensuring gear and bearing protection even during shock loads and dry starts. EXCELLENT THERMAL & OXIDATIVE STABILITY: The high-performance additive package maintains its protective properties even when differential temperatures soar during prolonged heavy use, preventing viscosity breakdown. ENSURES SMOOTH COLD STARTS & RELIABLE FLOW: With a pour point of -38°C (-37°F), this 75W-140 fluid maintains excellent pumpability for critical lubrication during cold-weather startups, protecting gears from dry starts.
