This heavy-duty front differential assembly serves as a direct OEM replacement drivetrain component built for Polaris Ranger and RZR series UTVs spanning model years 2011 through 2023, delivering reliable power distribution to the front wheels for off-road traction and stable four-wheel drive operation.

Constructed with high-strength cast iron housing, precision ground internal ring and pinion gears, heat-treated spider gears and multi-layer oil resistant sealing gaskets, this differential unit mounts directly to the front drivetrain of compatible Polaris off-road vehicles. Every mounting hole, shaft spline and bolt pattern matches factory OEM specifications perfectly, requiring no cutting, welding or custom modification to complete installation across all listed model trims and production years.

We reinforce the gear tooth surface hardness and upgrade the integrated seal system compared to stock factory differentials. The enhanced sealing structure greatly prevents gear oil leakage during muddy, rocky and high-load off-road use, reducing premature gear wear and drastically extending the service life of the front drivetrain assembly. The unit comes fully pre-filled with gear lubricant and pre-tested before packaging, eliminating tedious fluid filling and gear backlash adjustment steps to simplify installation for professional mechanics and UTV owners performing DIY repairs.

This replacement front differential resolves common chronic issues that plague aging Polaris Ranger and RZR front drivetrains, including loud grinding and whining noises during acceleration and four-wheel drive engagement, persistent gear oil seepage from the differential housing, difficulty locking into 4WD mode while traversing uneven terrain, excessive play in the front axle connection, and catastrophic gear failure that leaves the vehicle unable to engage front wheel drive and forces frequent costly component replacements.

It clears diagnostic trouble codes related to front axle drive system malfunctions and differential torque lock errors when scanned with standard UTV diagnostic tools.

Complimentary free standard shipping is available for all orders shipped within the contiguous United States. All in-stock items will be dispatched within 1 business day following payment confirmation, shipped directly from our domestic warehouse to shorten transit time with full end-to-end package tracking access.

Every OUSIMY front differential assembly is backed by a 2-year limited manufacturer warranty against material and production defects. Installation procedures align with official Polaris service manual guidelines, and basic hand tools are sufficient for experienced off-road vehicle enthusiasts to finish the swap independently and avoid expensive dealership service labor fees.
