Specifically designed for 2002-2008 Grizzly 660 models including all the different editions - standard, Hunter, Limited, Special, and DUCKS Unlimited versions.

Trying to remove or install that pinion nut without the proper tool is nearly impossible and can damage your differential. This tool fits perfectly and gives you the leverage you need to get the job done right.

Whether you're replacing bearings, seals, or doing a full differential rebuild, having the correct tool makes the difference between a professional repair and a frustrating mess.

Much cheaper than taking it to a shop, and you'll have the tool for future maintenance.

We strongly recommend comparing the photos to your existing nut to ensure proper fit before ordering. Comes as a single tool - straightforward and does exactly what it's supposed to. Serious ATV mechanics know that having the right specialty tools saves time, money, and headaches.
