RCV Performance Ultimate CV Axles simply replace the weak Dana 60 U-joint axle shafts with a high-strength constant velocity design. Tests prove Ultimate CV Axles to be twice as strong as OEM U-joint shafts.  CV shafts are just as tough at a straight angle as they are at extreme angles - where U-joints are weakest. We have gone a step further by upgrading the inner shafts to 300M, which provides an even greater tolerance to stress. Ultimate CV Axles also eliminate U-joint binding to allow smooth transfer power to the ground.  Even if you have big tires and big power there are no worries.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. Fits: Dana Spicer "Ultimate" Dana 60 housings for Jeep JK -JLAxle set includes right and left CV axle shafts, SST seals and installation tool, installation instructions, synthetic moly grease, and installation hardware.
