Factory CV's will run you close to $500 each new...ouch. I am running Empi's. They don't have a VX specific CV but the trooper ones work. I got them on Amazon for about $70 each. The quality is deffinately better than what you will get from autozone, checkers, etc...they sale remanufactured CV's. The Empi's are all new. So far, about 2 months, they are working well. Haven't had them off road yet to give them a good testing though
