HIGH PERFORMANCE GEAR OIL

FRICTION-MODIFIED EXTREME-PRESSURE LUBRICANT FOR LIMITED-SLIP DIFFERENTIALS

Close

High Performance Gear Oil is a premium, multi-purpose, extreme-pressure (EP) automotive gear lubricant specifically designed for use in passenger cars and light trucks. Formulated with high-quality paraffinic base oils and a "Limited Slip" (LS) friction modifier, it provides smooth, chatter-free operation in positraction and limited-slip axles without the need for additional additives. It is engineered to protect high-offset hypoid gear sets from scoring and wear under heavy loads and high-speed driving. This oil features exceptional thermal stability and oxidation resistance to prevent the formation of sludge and varnish, ensuring the long-term cleanliness and efficiency of the drivetrain. With robust protection against rust, foam, and copper corrosion, it is the professional choice for maintaining the peak performance of differentials, manual transmissions, and transfer cases in modern light-duty vehicles and high-performance racing applications.

PRODUCT RESOURCES 

PERFORMANCE

  • Friction-modified for smooth, chatter-free operation in limited-slip differentials.

  • Excellent thermal stability reduces oxidative sludge during high-speed highway driving.

  • Maintains consistent viscosity for reliable fuel economy and protection in light trucks.

PROTECTION

  • Superior EP additives prevent scoring and wear in high-offset hypoid gear sets.

  • Protects against metal fatigue and spalling during sudden "shock load" starts.

  • Fortified with rust and copper corrosion inhibitors to protect internal yellow metals.

UPTIME

  • Ready-to-use formulation eliminates the need for separate limited-slip additives.

  • Extended gear life for passenger cars, SUVs, and high-performance racing vehicles.

  • Compatible with a wide range of seal materials to prevent driveway leaks and oil loss.

FEATURES & BENEFITS

  • LS-Ready: Friction modified for immediate use in limited-slip and positraction axles.

  • Thermal Durability: Resists breakdown under the high heat of towing or racing.

  • Hypoid Protection: Specifically engineered for the sliding friction of automotive gear sets.

  • All-Season Flow: Ensures immediate lubrication to the axle on cold winter mornings.

APPLICATIONS

  • Passenger car and light truck axles (Conventional or Limited-Slip).

  • Racing vehicle differentials requiring GL-5 protection.

  • Service-fill for new or rebuilt limited-slip differentials.

MAMMOTH TECHNICAL TIP:

If you’re servicing a modern pickup or a 4x4 with a limited-slip diff, use this. It already has the "friction modifier" additive in the bottle. If you use a standard HD gear oil without it, the clutches will chatter and pop every time you take a tight corner.
