Honda Foreman & Rubicon Rear Differential Ring Gear + Axle Bearing & Seal Kit – TRX400 / TRX450 / TRX500 – Complete Rebuild Set

OVERVIEW

This complete rear differential rebuild kit restores reliable power transfer and bearing alignment on Honda Foreman and Rubicon platforms by replacing critical wear elements with precision-matched replacements. Engineered to strict dimensional tolerances, the assembly utilizes hardened steel ring gear components and durable seal designs that meet or exceed factory specifications.

ENGINEERING & PERFORMANCE

Precision-cut ring gears mesh smoothly with upgraded pinion and axle bearings, eliminating play and restoring factory differential clearance without altering final drive ratios. Sealed bearing assemblies retain adequate lubricant while external gasket-style and lip seals prevent mud, water, and debris from contaminating internal surfaces. Designed as a direct replacement for original hardware, the set eliminates guesswork during disassembly and speeds up reassembly with clearly separated, correctly sized components.

WHY RIDERS CHOOSE THIS

Owners select this comprehensive rebuild set because it replaces every failing component in a single purchase, preventing costly return trips for missing seals or backup bearings. The OE-specification ring gear and reinforced bearing packs maintain proper wheel alignment under heavy loads, while factory-style sealing architectures effectively block abrasive trail debris from reaching fresh metal surfaces. By addressing differential play, bearing failure, and seal blowouts simultaneously, this kit returns stock shifting behavior and quiet operation without dealer pricing. The model-specific grouping streamlines maintenance schedules for operators who push their Honda ATVs frequently through mud, rocks, and steep climbs.
