This front differential bearing and seal kit is a purpose-built refresh for Honda ATV front differentials, covering key TRX platforms including the 500 Foreman Rubicon variants and Rincon models. It bundles precision bearings and high-grade seals to restore smooth engagement, eliminate leaks, and maintain proper differential preload in off-road conditions. Replacing worn bearings and seals with this kit helps you avoid gear whine, reduced four-wheel drive reliability, and costly drivetrain damage on the trail or the farm.

Engineered as an aftermarket replacement, this kit delivers OEM-like fit and performance without the OEM price tag. It’s designed for harsh off-road environments where mud, water, and dust can accelerate wear, providing dependable durability and straightforward installation for riders who demand consistent traction and long service life from their front drive.

Comprehensive Vehicle Fitment

Compatibility is confirmed for Honda front-diff applications on TRX 500 Foreman Rubicon (FA/FE/FGA/FM) and Rincon variants (TRX650/RINCON and TRX680/RINCON), across the model years listed below.

Installation Notes:

• Drain and inspect the differential oil before disassembly to minimize contamination and clarify wear patterns.
• Remove old seals carefully and clean mating faces to ensure a proper seal seating surface.
• Check bearings for play and inspect gear teeth for pitting or chipping once the differential is exposed.
• Lubricate seals with fresh gear oil before installation to ease seating and improve sealing life.
• Orient seals correctly and use the appropriate installation tool to avoid lip damage; verify seal seating flush with the housing.
• Reassemble with clean surfaces, replace O-rings where applicable, and refill with the recommended oil to the correct level after assembly.

Why Upgrade?

Running a worn front-differential bearing or seal can lead to progressive oil leaks, reduced four-wheel-drive engagement, and accelerated gear wear. This replacement restores proper preload and sealing, reestablishing reliable front-drive performance and extending the life of the entire front differential drivetrain.
