Recommended for use in differentials, manual transmissions and other gear applications requiring any of the following specifications: API GL-5, MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037), Mack GO-J, or other GL-5 based specifications from vehicle manufacturers, including Ford*, GM* and Chrysler*. Can also be used in axles where an API GL-4 lubricant is recommended.

AMSOIL Severe Gear� 100% Synthetic Extreme Pressure (EP) Gear Lube is a premium grade gear oil specifically engineered for maximum performance in server-duty applications. It maintains its viscosity for long-lasting protection against metal-to-metal contact. The proprietary AMSOIL additives from an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defence against wear, pitting and scoring. AMSOIL Severe Gear helps prevent “thermal runaway”  a phenomenon caused by a lubricant’s inability to control friction and increased hear under high-stress conditions. By controlling thermal runaway, AMSOIL Severe Gear 100% Synthetic EP Gear Lube inhibits rapid lubricant degradation and component damage  helping equipment run better and last longer.
