Grizzly 660 Hot Rod Extreme Clutch Kit w/ Secondary Spring, Grease, OEM 700 Belt & OEM Fixed Sheave – The best overall clutch kit available on the market.

This sheave is milled for even more bottom & top end, it`s the perfect combination of both performance & quality. Great for trail, mud and sand riding as well as rock crawling, plowing and hauling.

• This kit changes the gear ratio on the bottom & the top of your bike. A huge gain on low end power and torque, a stronger midrange & more on top end too.
• The extra top end is nice when you want to run low range so it doesn`t max out so quickly from mud hole to mud hole, trail riding, or working in the yard or farm.
• Helps restore power loss due to adding bigger/heavier tires & helps to get them turning in the mud. Better back shifting & throttle response.

The lower gearing on bottom end will extend the life of your wet clutch. The higher gearing on top will extend the life of your motor. Reduces clutch heat & engine noise.
