2inch Spacer lift – is it causing issues?

Picked up a RZR 800 that has a 2 inch spacer lift on it, doesnt look like its maxed out but theres some serious play in the prop shaft. I’ll be replacing that shortly, my question is though, is the 2 inch spacer lift and 27 inch mud tires causing extra strain on the prop shaft and causing it to fail? Or is this a normal wear and tear item on these guys? I’ve read its a pretty common issue that seems to stem from not greasing the grease fittings enough but I just want to make sure that I get this thing mechanically sound and dont want a reoccuring issue if this cheap lift is the problem.
