Quantity: 5 pieces AMSOIL SEVERE GEAR® 75W-85 100% Synthetic Gear Lube is a fully synthetic oil designed to provide maximum protection and performance under the harshest operating conditions. This oil is ideal for use in differentials and transmissions that require this type of lubricant. Key Features and Benefits 1. Superior Protection Against Wear and Extreme Pressure Specially formulated to withstand high loads and extreme pressure, reducing friction and preventing wear between metal gear surfaces. Contains unique additives that form a protective iron sulfide layer on gear surfaces, providing the ultimate defense against wear and damage. 2. Excellent Performance in Extreme Temperatures Maintains its viscosity and properties at very high temperatures, preventing "thermal runaway" which leads to oil degradation and component damage. Its wax-free formulation ensures superior fluidity at low temperatures, facilitating operation and improving transmission and differential performance in cold weather. 3. Extended Component Life Reduces operating temperatures, extending the life of the oil itself, as well as the life of seals and internal components. Contains rust and corrosion inhibitors, ensuring gears and bearings remain in excellent condition for longer. 4. Improved Performance Reduces friction, contributing to increased overall vehicle efficiency. Contains built-in friction modifiers, making it suitable for use in limited-slip differentials without the need for separate additives. 5. Versatile Applications Suitable for a wide range of cars and trucks requiring 75W-85 viscosity. Ideal for heavy-duty applications such as towing and heavy hauling, commercial driving, racing, and off-road driving.
