I probably don't ride as hard as Ranger 29.5 but I have 29.5's a 2" lift kit, 2" offset A-Arms, and 1.0" wheel spacers. I have a little rub if I hit a big hole hard. I have had no issues with my axles or cv joints. I am sure I am putting more stress on them, but what fun is it having it stock. The gorilla axles are made for 30 degrees of travel I believe and they are built strong. However they are costly. I say run what you got, take it easy and save some money along the way. You never know they might not wear out any sooner. Driver's foot can cause alot of problems. I have seen it to many times while jeeping as well.
