MOOSE OFFROAD 25-1787 Rear Wheel Bearing & Seal Kit — Yamaha YXZ1000R / Wolverine X2 X4

MOOSE OFFROAD — High-Speed Precision, Double-Lip Water Protection, and Heavy-Duty Hub Restoration for Yamaha UTVs

Eliminate wheel wobble and restore the smooth, high-speed stability of your Yamaha with the MOOSE OFFROAD 25-1787 Rear Wheel Bearing Kit. Specifically engineered for the high-performance Yamaha YXZ1000R and the versatile Wolverine X2/X4 platforms (MX1 hubs), this kit is designed to withstand the extreme lateral loads and harsh environments of off-road racing and adventure touring. Whether you're hitting the dunes or technical mountain trails, these premium bearings ensure your drivetrain operates with minimal drag and maximum reliability.

Every MOOSE OFFROAD kit is packed with Chevron SR1-2 high-performance grease, featuring advanced rust and oxidation inhibitors. To keep that lubrication in and contaminants out, the kit utilizes TC nitrile elastomer seals with a double-lipped rubber design. These seals feature a steel garter spring to maintain constant pressure on the axle shaft and a rubber-coated outside diameter for an airtight seal at the hub. Using EMQ (Electric Motor Quality) high-speed bearings, this kit provides a "better than stock" feel that reduces friction and extends the life of your rear suspension components.

• Complete Rear Wheel Solution: Includes all necessary bearings and seals to fully refit a single rear wheel hub.
• Superior Contaminant Exclusion: Double-lipped TC nitrile elastomer seals keep out water, dirt, sand, and trail grit.
• Premium Lubrication: Pre-packed with Chevron SR1-2 high-performance grease to prevent rust and oxidation in wet conditions.
• Constant Pressure Seal: Integrated steel garter springs guarantee a tight fit against the axle for long-term protection.
• High-Speed Precision: EMQ quality, low-drag bearings designed for the high-RPM demands of the YXZ1000R.
• Optimized Hub Fit: Rubber-coated seal OD ensures a perfect, leak-free interface with the Yamaha MX1 hub.

Moto-House MX Pro Tip:

The Yamaha YXZ1000R and Wolverine X2 are built for aggressive driving, but water crossings and pressure washing are the natural enemies of wheel bearings. If you notice play when shaking your wheel at the 12 and 6 o'clock positions, your bearings are shot. When installing the MOOSE OFFROAD 25-1787 kit, we recommend chilling the bearings in a freezer for an hour before installation—this "shrinks" them slightly, making them much easier to press into the hub without damage. Always use a proper bearing driver and avoid hitting the inner race to ensure your new bearings spin smooth for seasons to come.
