Gear Oils

Whether you're servicing a differential, manual transmission, or transfer case, the right gear oil is critical for long-term durability and quiet operation. Our collection includes a full spectrum of gear lubricants from trusted manufacturers, covering common viscosities, GL ratings, and both conventional and synthetic formulations.

Key considerations when selecting gear oil:

  • API GL Rating: GL-4 for moderate hypoid gears (many transaxles), GL-5 for high-pressure hypoid differentials. Some applications demand a specific rating—check your service manual.
  • Viscosity: Single-grade (SAE 80, 90, 140) and multi-grade (75W-90, 80W-90) options suit different temperature ranges and gear loads.
  • Base Oil: Conventional mineral-based oils are cost-effective for standard duty; synthetic fluids offer better thermal stability, reduced friction, and longer change intervals—especially in towing or performance applications.
  • Limited-Slip Friction Modifiers: Many differentials require a dedicated additive or a gear oil already formulated for clutch-type limited-slip units.

Browse by viscosity, brand, or vehicle application to find the correct fill for your project. Always consult your owner’s manual or a trusted reference for the exact specification before ordering.
