Product Specifications: Genuine OEM Polaris Fill Plug, Part # 2203739.

Restore Ultimate Traction with Genuine Polaris Gearcase Assemblies

When you are deep in the mud or climbing a rocky incline, your drivetrain's reliability is the only thing that matters. A failing differential or a cracked housing can turn a great ride into an expensive recovery mission. To ensure your 4WD system engages perfectly every time, you need a Polaris UTV/ATV OEM front, rear gearcase assembly & Components.

At Witchdoctors.com, we provide factory-new Original Equipment Manufacturer (OEM) assemblies that are ready to bolt in. These are not refurbished or "will-fit" aftermarket units; they are the exact same high-performance components used on the Polaris assembly line. Choosing OEM means you are getting the precise gear ratios, shim tolerances, and internal hardening required to handle the massive torque of the modern Polaris lineup.

Engineered for Strength, Precision, and Performance

The Polaris UTV/ATV OEM front, rear gearcase assembly & Components are designed to operate under extreme stress. By choosing genuine Polaris replacements, you secure several critical advantages:

  • Instant AWD Engagement: OEM front gearcases feature the specific armature plates and rollers needed for the Polaris "On-Demand" True All-Wheel Drive system to lock in instantly.

  • Hardened Internal Gearing: Gear sets are precision-ground and heat-treated to resist chipping and shearing under high-load situations.

  • Watertight Integrity: Factory seals and heavy-duty cast housings prevent water and silt from contaminating your gear oil.

  • Quiet and Smooth Operation: Unlike noisy aftermarket units, OEM assemblies are balanced to reduce driveline vibration and "gear whine."

  • Drop-In Compatibility: No modifications to your frame, CV axles, or drive shafts are required for installation.

Popular Gearcase Assembly Parts & Driveline Accessories

A gearcase swap is the best time to refresh your entire drivetrain. Consider these related components:

  • Gear Oil: Use only Polaris-approved lubricants to protect your warranty and internal clutches.

  • Front Output Shaft: Prevent leaks at the CV axle entry points.

  • Armature Plates and Roller Kits: Essential for repairing front "On-Demand" engagement issues.

  • Oil Drain Plugs: Replace stripped or leaking plugs with magnetic OEM versions.

  • Pinion Seals and Bearings: Maintain the connection between your driveshaft and gearcase.

Frequently Asked Questions (FAQs)

Do these gearcase assemblies come pre-filled with oil? Most OEM assemblies are shipped "dry" to prevent leaks during transit. You must fill them with the correct Polaris Demand Drive or Angle Drive fluid before operation.

How do I know if I need a full assembly or just a rebuild kit? If your gearcase housing is cracked or if there is internal metal debris that has scored the casting, a full assembly is recommended. For simple engagement issues, a rebuild kit may suffice.

Are the gear ratios the same as my factory unit? Yes. By using the specific OEM Part # for your VIN, you are guaranteed to match the factory gear ratio, which is critical for maintaining synchronized front and rear wheel speeds.
