Im having my 2012 JKU on 37" re geared to 4:88 and the shop showed me RCV axle as a possible upgrade. Seems like a smart thing to do but its pretty expensive. My question is how what is the likely hood I will damage my current U Joints? Is it enviable? Will moderate wheeling once a month take them out or serious off road abuse? I don't mind spending the money if the juice is worth the squeeze. Any experiences would be great.
Going to 4:88 should I upgrade U Joints or RCV?
