$24.99
Max Gear is recommended for truck and automotive differentials, outboard motor lower units or in rear axles or manual transmissions requiring an API fluid.

Gears run smoother, quieter, cooler and longer without overhauls. It is noncorrosive to both ferrous and nonferrous metals.

Product Features:
  • Maximizes horsepower
  • Extends gear and bearing life
  • Reduces operating temperature
  • Lower coefficient of friction
  • Superior corrosion protection
  • Separates rapidly from water
