Red Line 75W140 GL-5 Gear Oil - Gallon (4-Pack)

Red Line 75W140 GL-5 Gear Oil Gallon 4-Pack | Synthetic Drivetrain Protection

Buy a 4-pack of Red Line 75W140 GL-5 Full Synthetic Gear Oil. Designed for heavy-duty differentials, limited-slip units, and extreme pressure hypoid gears. 

Red Line 75W140 GL-5 Gear Oil is a premium, full-synthetic lubricant engineered to handle extreme pressure and severe thermal stress. Built using high-quality polyol ester base stocks, it maintains stable viscosity and film thickness across fluctuating temperatures. This gallon 4-pack bundle is ideal for servicing trucks, performance cars, and racing setups that demand robust protection for hypoid gear sets. It comes pre-blended with friction modifiers to support clutch-type limited-slip differentials without needing extra additives.

Best Uses:

• Heavy-Duty Truck Differentials: Ideal for high-capacity rear axles in trucks and SUVs subjected to heavy loads.
• Limited-Slip Drivelines: Perfect for clutch-type limited-slip differentials requiring smooth, chatter-free lock-up.
• Motorsports & Racing: Provides elite gear protection and reduced friction for track cars and endurance racing.
• High-Performance Street Vehicles: Excellent upgrade for muscle cars, sports cars, and performance road vehicles.
• Towing Applications: Protects rear-end components from overheating under continuous towing and hauling stress.

5 Key Features:

1. Polyol Ester Formulation: Advanced synthetic base stocks deliver exceptional thermal stability and continuous film strength.
2. Integrated Friction Modifiers: Formulated to support clutch-type limited-slip differentials right out of the bottle.
3. High Viscosity Index: Maintains consistent viscosity and protection across extreme temperature swings.
4. Extreme Pressure Additives: Protects heavily loaded hypoid gears from shock loads, scoring, and premature wear.
5. Multi-Quart Gallon Containers: Packaged as four one-gallon jugs to cover large capacity or multiple differential services.

5 Key Benefits:

1. Lower Operating Temperatures: Reduces sliding friction in hypoid gears to cool down hot-running differentials.
2. Superior Shear Stability: Resists thinning and breakdown under severe mechanical loads better than conventional oils.
3. Enhanced Drivetrain Efficiency: Minimizes internal friction to improve overall vehicle efficiency and mileage.
4. Smooth Limited-Slip Performance: Minimizes chatter and maximizes locking performance in specialized differentials.
5. Extended Drain Intervals: High oxidation resistance allows for longer service intervals under demanding driving conditions.

This product is not designed for use in most manual transmissions or transaxles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems. This is for a pack of 4 one gallon bottles of oil.
