Red Line 75W90 GL-5 Gear Oil

Product information

Red Line 75W90 is a premium fully synthetic GL-5 gear oil for differentials and final drives requiring maximum protection. Its ester-based formula provides a strong lubricating film, excellent shear stability and reliable protection under high loads and temperatures. We advise this in clutch type LSD's or OEM Fuji clutch differentials. For gearboxes and torsen/helical differentials we advise 75w90NS.

The integrated friction modifier makes it suitable for many clutch-type limited-slip differentials, helping to reduce chatter while maintaining smooth operation. Low fluid friction can also reduce power loss and improve efficiency compared with conventional gear oils.

Key benefits:

• Fully synthetic, ester-based formulation
• API GL-5 protection for hypoid gears
• Suitable for many limited-slip differentials
• Excellent stability at high temperatures
• Helps reduce wear, gear noise and friction
• Flows well during cold starts
• Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears

Always follow the vehicle or component manufacturer’s viscosity and performance specifications.
