Mopar 75W-85 Synthetic Axle Lubricant 2-Quart — OEM gear oil for Chrysler Dodge Jeep Ram, full-synthetic protection

Mopar SAE 75W-85 synthetic axle lubricant is an OEM-formulated gear oil in a 2-quart bottle designed to protect and lubricate Chrysler, Dodge, Jeep and Ram differentials and axle assemblies under everyday driving loads.

This full-synthetic axle lubricant meets Mopar specifications for modern FCA vehicles that call for a 75W-85 viscosity rating. It provides stable film strength and consistent viscosity across a range of temperatures to support smooth gear engagement, reduce wear, and help extend service intervals when used as part of routine maintenance.

What vehicles and components is this gear oil meant for?

This Mopar 75W-85 synthetic axle lubricant is intended for front and rear differentials, final drives and manual transaxles specified by Mopar or FCA requiring SAE 75W-85. Always check the vehicle owner’s manual or dealer parts bulletins to confirm the correct fluid for your model and year.

• OEM-specified for many Chrysler, Dodge, Jeep and Ram rear and front axles
• Suitable for hypoid gear sets and conventional differentials per Mopar guidance
• Works in both passenger cars and light trucks where 75W-85 is recommended

How does this synthetic formulation help performance?

The synthetic base and additive package provide stable lubrication across temperature extremes, supporting consistent shifting and reduced metal-to-metal contact. That stability helps maintain gear protection under load and can reduce noise compared with degraded or incorrect fluids.

• Broad temperature protection for cold starts and hot operating conditions
• Enhanced film strength to resist shear and gear wear
• Corrosion inhibitors and anti-foam additives to protect internals

How should I use and store the 2-quart Mopar bottle?

The product ships in a ready-to-pour 2-quart container with a secure cap — ideal for a differential or axle service at home or in a shop. Follow vehicle manufacturer fill capacities and torque specs for the fill plug, and store the bottle upright in a cool, dry place away from direct sunlight.

• Use a clean funnel and follow the vehicle fill capacity listed in the manual
• Close the cap tightly after use to prevent contamination
• Store between recommended temperatures and keep away from ignition sources

Does this meet OEM standards and warranty considerations?

As an official Mopar product, this axle lubricant aligns with FCA/Mopar specifications where 75W-85 is required. Using Mopar-branded fluids helps ensure compatibility with factory warranties when service schedules call for Mopar-approved fluids.

• Manufactured to Mopar engineering and specification guidance
• Helps preserve factory service recommendations when used as specified
• Keep purchase receipts and service records for warranty documentation

Who this is for: This 2-quart Mopar SAE 75W-85 synthetic axle lubricant is aimed at owners and technicians who maintain Chrysler, Dodge, Jeep and Ram vehicles that require a 75W-85 axle fluid. It’s suitable for DIY mechanics performing differential services, independent shops seeking OEM-specified fluids, and fleet managers who prefer Mopar parts for consistency and warranty alignment.
