MOOSE RACING Rear Differential Bearing and Seal Kit TRX300 TRX 300 FourTrax TRX300FW

OVERVIEW

Engineered to replace worn or failing components inside the rear differential, this kit restores smooth rotational power transfer and prevents gear damage from oil starvation or contamination. The product is a complete bearing and seal set constructed with high-speed EMQ steel bearings and durable TC rubber seals. It delivers a direct, hassle-free overhaul designed specifically for 1988–2000 Honda TRX300 and TRX300FW FourTrax models.

ENGINEERING & PERFORMANCE

High-speed EMQ bearings are manufactured to withstand sustained torque loads while maintaining tight tolerances that reduce internal friction and heat buildup. Type TC rubber seals incorporate garter-spring inner lips that apply steady radial pressure against the bearing race to keep dirt and moisture out. The rubber-covered outside diameter adds a second layer of defense, ensuring optimal sealing performance across varied terrain conditions. As a fully inclusive service kit, it consolidates all necessary replacement hardware into one unit, streamlining differential teardowns and eliminating compatibility guessworks during assembly.

WHY RIDERS CHOOSE THIS

Proper differential maintenance is essential for retaining predictable handling and preventing costly internal gear failures on trail machines. Riders prefer this kit because the combination of precision-machined EMQ bearings and reinforced TC rubber seals delivers long-term abrasion resistance and stable grease retention. The garter-spring tension and fully coated seal exteriors work together to maintain a clean internal environment, which translates to smoother power delivery and extended service intervals. Because every required bearing and seal is packaged together in exact factory specifications, both professional shops and home mechanics can restore the rear end to reliable working condition quickly.
