Red Line Oil 57904(QTY2) 75W90 GL-5 Synthetic Gear Oil 2 Quart Package

Red Line 57904 is a fully-synthetic 75W90 GL-5 gear oil designed for maximum protection in differentials and racing transmissions. This 2-quart package provides premium lubrication formulated with polyol ester base stocks that deliver exceptional performance under extreme high-load and high-temperature conditions.

Key Features:

• Fully-synthetic polyol ester base stocks provide superior lubrication and film strength
• Contains friction modifiers for clutch-type limited slip differentials—most LSDs require no additional additives
• High viscosity index maintains stable viscosity across temperature extremes
• Exceeds API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler MS-9763 specifications
• Reduces operating temperatures by minimizing sliding friction in hypoid gears
• Superior shear stability and oxidation resistance compared to conventional gear oils
• Suitable replacement for differentials calling for 80W90 or SAE 90 gear oil

Applications: The most popular Red Line gear oil with thousands of applications for passenger cars, light trucks, and racing vehicles. Ideal for differentials in both conventional and limited-slip configurations. Not recommended for most manual transmissions or transaxles in passenger vehicles due to extreme slipperiness that may affect synchronizer operation.

Engineered to provide the highest degree of protection, improved differential efficiency, better fuel mileage, longer drain intervals, and reduced wear. Each package contains two 1-quart bottles.
