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.
Performance Features

Performance
AMSOIL SEVERE GEAR provides performance far beyond what is possible with conventional gear oil. We design our gear lubes to provide superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life.

Temperature Extremes
SEVERE GEAR excels in hot and cold temperature extremes. By design, it resists breakdown from high heat, preventing acid and carbon/varnish formation. Its wax-free construction also improves
cold-flow properties, improving fuel economy and cold-weather shifting.
