AMSOIL Severe Gear Synthetic SAE 250 Gear Lubricant is a premium grade, extreme pressure gear lube engineered specifically for the demands of severe racing conditions. They are formulated with shear stable, heavy synthetic base oils for high film strength and extra heavy treatments of additives. Our gear lube synthetic formulations provide improved flow over conventional oils, reducing viscous drag and power loss. SAE 250 synthetic gear lube provides a barrier cushion between metal surfaces that absorbs impact. AMSOIL synthetic gear lubricant proprietary extreme pressure additives form an iron-sulfide barrier coating on gear surfaces for the ultimate line of defense against wear, pitting and scoring.

PERFORMANCE
AMSOIL's Synthetic Gear Lubricant is specifically engineered for high horsepower, high torque conditions where centrifugal gear lube sling-off is encountered. These tenacious formulations cling to gears and bearings for the best possible protection during shock loading, high G-forces and where pinion gears are installed at steep angles. Custom Severe Gear Synthetic Gear Lubricants provide exceptional reliability and extended gear life.

  • Protects gears from shock loading and tire shake
  • Resists sling-off from G-forces and high speeds
  • Clings to gears - high pinion style and at steep angles
  • Promotes cooler operating temperatures
  • Protects against rust and corrosion
  • Extends gear and bearing life

APPLICATIONS
AMSOIL Gear Lube is excellent for severe differential applications, including off-road truck racing, rock racing, rock crawling, tractor pulling, funny car racing and dragster racing. Other severe duty applications include heavy duty trucks and equipment where increased lubricant film is necessary. These oils are recommended for use in hypoid gear differentials and other applications requiring a high viscosity, API GL-5 gear lube. Where limited slip performance is required, use AMSOIL Slip-Lock limited slip additive.
