Xtreme Duty 80W-90 Gear Oil

Xtreme Duty™ 80W-90 Premium Performance Gear Oil is a high-performance, multi-grade lubricant engineered to protect heavily loaded gears from scuffing, wear, rust, and corrosion.

Quality base oils and a carefully selected extreme-pressure additive system provide the load-carrying strength needed to maintain protection across demanding drivetrain applications. The formulation protects critical gear surfaces under heavy loads while supporting dependable operation in automotive axles, gear sets, differentials, and conventional transmissions requiring API GL-5 performance.

Recommended for heavy-duty and light-duty trucks, passenger vehicles, and both conventional and limited-slip differentials.

Formulated for the Controlled Operating Environment™

The Controlled Operating Environment™ is The Hub Corporation’s system-level approach to preserving stable, protective conditions inside critical mechanical assemblies.

Xtreme Duty™ Gear Oil supports that environment by maintaining a durable lubricating film, controlling oxidation and deposit formation, protecting against rust and corrosion, and helping preserve seal integrity. The result is a cleaner, more stable lubrication environment designed to help drivetrain components perform reliably and reach their intended service life.

Key Features:

• Extreme-pressure protection: Protects gears from scuffing and premature wear, helping expensive drivetrain components remain in service longer.
