These front differential drive shaft couplers are replacement driveline components that connect and cushion the front drive shaft on select Yamaha Grizzly YFM660 models from the 2005 and 2006 production years.

Overview

These front differential drive shaft couplers serve as the connecting link between the front drive shaft and the differential on select Yamaha Grizzly YFM660 FA and FASE models.

Good To Know

Q: How do I know these couplers fit my machine? A: Confirm your model and year match the YFM660 FA or FASE fitment listed above before ordering. Serial number checks can help verify the correct front driveline parts for your Grizzly.

Q: Do I need to replace both sides at once? A: Replacing the couplers as a matched set keeps front driveline wear even. Inspect the shafts and differential for play while the couplers are removed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
