MOOSE RACING Rear Wheel Bearing Kit for Honda TRX300 FourTrax TRX300FW FourTrax 4x4

OVERVIEW

This rear wheel bearing kit delivers reliable rotational support and long-lasting durability for aging ATV wheel hubs. Constructed with high-speed, low-drag EMQ bearings and reinforced with specialized sealing components, it ensures precise axle alignment while keeping trail debris out. Designed specifically for vintage Honda three-wheeler platforms, this complete service kit restores proper wheel function without requiring aftermarket modifications.

ENGINEERING & PERFORMANCE

The kit relies on high-speed, low-drag EMQ bearings to minimize rotational friction and maintain smooth wheel operation under heavy loads. Double-lipped rubber seals combined with type TC nitrile elastomer provide consistent barrier performance against mud, sand, and moisture ingress. A precision-tensioned steel garter spring maintains unbroken contact pressure against the axle shaft, preventing seal blowouts and locking fresh lubricant inside the hub assembly. Each seal features a rubber-coated exterior diameter engineered to seat tightly against the wheel casing for leak-free sealing during field use.

WHY RIDERS CHOOSE THIS

Riders choose this kit because it replaces failing original equipment components with a comprehensive, ready-to-install bearing and seal package. The dual-seal strategy—combining double-lipped rubber with steel garter tension and TC nitrile elastomer—effectively blocks grit and moisture while keeping track of factory-approved lubricants. Low-friction EMQ bearings reduce rolling resistance and hub heat buildup during prolonged trail or farm work. Because every required part is included and dimensionally matched to vintage Honda three-wheeler hubs, mechanical installations stay straightforward and return the rear end to stable, predictable rotation.
