Designed for demanding drivetrain environments, Genuine Mopar SAE 75W-140 Synthetic Gear Oil (MS-8985) delivers robust protection for differentials, transfer cases, and axle assemblies that require a heavier viscosity lubricant. Its advanced synthetic formulation helps sustain performance, resist shear, and support reliable operation under towing, off-road, or high-load driving conditions where conventional gear oils can struggle.

Built for Heavy-Duty Lubrication

Thicker Viscosity for Tough Conditions: SAE 75W-140 offers enhanced film strength in high-temperature and high-stress applications, helping maintain proper lubrication where heavier oils are specified.

Premium Synthetic Base: Engineered to flow consistently while resisting thermal breakdown, oxidation, and viscosity loss over time.

MS-8985 Specification: Meets Mopar’s material and performance standards for vehicles calling for this specific gear lubricant.

Extended Wear Protection: Advanced additives help shield gear teeth, bearings, and seals from wear, pitting, and corrosion.

1-Quart Packaging: Ideal size for scheduled differential or axle fluid service.

Why This Matters

Proper gear oil plays a crucial role in the life of your drivetrain components. Under severe heat, heavy load, or frequent starts and stops, a high-viscosity synthetic lubricant like SAE 75W-140 helps preserve oil film and reduce metal-to-metal contact that can accelerate wear. Using genuine Mopar fluid helps ensure compatibility with factory materials and performance expectations.
