Rear Differential & Axle Bearing and Seal Kit – Fits Honda TRX300 / TRX300FW 1988–2000 – Complete OE‑Spec Rebuild Set

OVERVIEW

This comprehensive rebuild kit restores rear driveline integrity by replacing worn journal supports and protective seals on select Honda ATVs. Engineered as a complete assembly set, it supplies every necessary bearing and gasket to eliminate guesswork during teardown and reassembly. Manufactured in Taiwan to strict manufacturer specifications, this component package ensures reliable routing and extended service intervals for your 1988–2000 Honda TRX three-wheeler.

ENGINEERING & PERFORMANCE

Precision-machined steel bearings and reinforced synthetic seals work together to minimize internal friction and maintain consistent torque delivery under heavy load. The complete component layout shields sensitive differential internals from moisture intrusion and abrasive debris, which are primary drivers of premature gear failure. Built to factory tolerances, every bearing and seal aligns directly with original mounting points for predictable operation and sustained mechanical reliability.

WHY RIDERS CHOOSE THIS

Riders prefer this kit because it addresses a frequent service gap by including the brake panel bearing and backing plate O-ring that many rival sets leave out. Covering every load-bearing point ensures clean lubrication pathways, which prevents dirt ingress and maintains smooth rotational force through the final drive. The Taiwan-produced components meet rigorous dimensional calibrations, allowing them to seat flush without play or binding stress. This comprehensive approach cuts workshop labor time while delivering factory-calibrated performance specifically matched to the Honda TRX three-wheeler chassis.
