Red Line 57904 is a premium fully-synthetic 75W90 GL-5 gear oil formulated with advanced polyol ester base stocks for superior protection in differentials and hypoid gears. This package includes four 1-quart bottles of Red Line's most popular gear oil, trusted by automotive enthusiasts and racers worldwide.

Key Features:

• Fully-synthetic formulation using polyol ester base stocks for exceptional lubrication and thermal stability
• Contains additional friction modifiers specifically designed for clutch-type limited slip differentials
• Exceeds API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler MS-9763 specifications
• Superior shear stability and oxidation resistance compared to conventional gear oils
• Natural multigrade properties provide stable viscosity across wide temperature ranges
• Reduces operating temperatures and friction for improved differential efficiency
• Suitable replacement for differentials calling for 80W90 or SAE 90 gear oil

Applications: Designed for passenger cars, light trucks, and racing vehicles with hypoid differentials. Most popular for rear differentials requiring GL-5 specification gear oil. For most limited slip differentials, no additional friction modifiers are required.

Important Note: This product is not recommended for most manual transmissions or transaxles in passenger vehicles, as the extreme slipperiness may cause synchronizer mesh issues leading to shifting problems.
