I must say I am VERY impressed with a tusk clutch. I put one in my cub, and thought I melted it the first ride. I was pissed. After taking the clutch out and apart, the inner and outer hubs where wore out, making my clutch heat up and not work right. I rode it like that for a whole weekend, and amazing enough, it didnt hurt the tusk clutch at all... I would have to say they are well worth the 40 bucks.
