Good To Know

Q: Will this fit my 2005 Grizzly 660? A: It is built for Yamaha Grizzly YFM660 models from 2003 through 2008, so it matches those model years. Confirm your machine's exact model and year before ordering.

Q: Do I need to replace the couplers too? A: The couplers are included with this drive shaft, and replacing them alongside the shaft is recommended when the originals show wear. Worn couplers can cause play even with a new shaft.

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