RCV Performance Ultimate CV Axles simply replace your Jeep JK's weak Dana 44 U-joint axle shafts with a high-strength constant velocity design using 300M aerospace-grade inner axle shafts. Tests prove Ultimate CV Axles to be twice as strong as OEM Jeep JK shafts, and they're 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 of 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.
300M is the same ultra-high-strength steel alloy used in aerospace applications and top-level motorsports - the maximum strength option for your JK Dana 44 build.
Axle set includes: right and left CV axle shafts, SST seals, synthetic moly grease, and installation hardware. Black oxide coating is standard. Optional nickel plating available.
