I have the rough country 2.5 inch lift kit and I keep experiencing right axle problems just the right side my CV boots keep tearing and I don't do anything hardcore with it just some mud when I do go off-roading . I have 31s so its not like my tires are insanely large or anything. But last boot broke with in 2 months and the drivers side is still original not that I want it to break too just confuses me that its one side and not the other, are there like longer axles I could get that wouldn't tear ? The axles don't seem overly stressed just the boot tears are the Zr2 axles longer ? Is there a company that makes better ones more suited for being at an angle or would axle spacers be okay just to ease the stretch ? I've heard that puts too much stress on the internal components of the axle

 

You can try to find an axle that has more folds/ ribs in the boot. I know there are some out there. Or back off the tbar crank abit

 

I cranked it down like a quarter inch see what happens can't go too low or the tires will rub
