Description:

This is a brand‑new, high‑quality aftermarket rear axle shaft designed for select Yamaha Big Bear 350 and Kodiak 400 models. Built to meet or exceed OEM specifications, this axle features an anodized finish to resist rust and corrosion. It is a direct replacement for Yamaha OEM part number 4WU‑25381‑00‑00 and works with your stock hubs.



This axle is a cost‑effective alternative to the OEM unit, which can cost nearly $700 from Yamaha. Perfect for restoring proper driveline performance on older Big Bear and Kodiak models.

• This axle ONLY fits the **1997 Yamaha Big Bear 350 SE Special Edition** (YFM350FWBJ).
