RCV Big Bell CV Axle Set for 40 spline Dynatrac PROROCK XD60™ 72.5" for Jeep JK – RCV Performance part number CVJRCK-XD60-72.5.

RCV Performance Big Bell CV Axles simply replace the weak Dana 60 U-joint axle shafts with a high-strength constant velocity designed for 2.5 ton Rockwells. Strongest option on the market. CV shafts are just as tough at a straight angle as they are at extreme angles - where U-joints are weakest. Ultimate CV Axles also eliminate U-joint binding to allow smooth transfer power to the ground.

Ultimate CV Axles are low maintenance and operate with a smoothness you can feel - whether off road or on the street. And we back it all with a "No Questions Asked" limited lifetime warranty.
