I was looking at some threads on the Arctic Cat side and noticed that people over there complain a lot about CV joint failures. Could that be because of the extreme angle they run at? I know that when I used to wheel in my Jeep with guys that had Toyotas, they'd only break a birfield or CV (in IFS trucks) when they had the wheel cranked, or they had a really tall lift without relocator brackets. Since most ATV lifts are just brackets to make the shocks 'longer' to push down farther on the suspension, could they contribute to CV failures prematurely?

 

I agree with you asumption. Years ago when I was looking into a lift kit for my jeep I read an article about how much extra stress is placed on the u joints by adding a couple of inches of lift. ATVs have much shorter lengths and greater angles. A cv joint is really a real fancu ujoint and might give a bit more angle than a ujoint would, but I bet they already designed for max angle to get max ground clearence.
