Ring Gear For Honda TRX 250 Recon Fits TRX 520 420 250 SXS 520 500 2001 To 2022

This Ring Gear is a purpose-built aftermarket replacement designed to restore reliable final-drive performance on the TRX Recon family and related TRX 250/350/450/500/520 models. It replaces the OEM 41431-HM8-000 with exact-fit geometry, delivering proper mesh and durable operation for trail work or farm use. Crafted from hardened alloy steel and machined to precise tolerances, it helps quell gear noise, minimize backlash, and protect the rear differential from wear under load.

Why this aftermarket ring gear stands out is its direct-fit design and robust material construction, which stand up to the rigors of muddy trails and heavy-duty use. It’s engineered to address common wear-and-tear symptoms like chipped or worn teeth, excessive play, and intermittent engagement in the final drive, providing a reliable, long-lasting replacement that keeps you moving when you’re far from the shop. This makes it a practical, value-driven choice for serious trail riders and farm operators alike.
