Description

RCV Performance Ultimate CV Axles replace JK 44 U-joint axle shafts with a high-strength constant velocity design. Twice as strong as OEM, they perform equally well at straight or extreme angles, eliminating U-joint binding for smooth power transfer. Low maintenance, ideal for big tires/power, and suitable for off-road or street use. The set includes right/left CV axle shafts, outer stubs, SST seals, installation tool, instructions, synthetic moly grease, and hardware. Black oxide coating is standard; optional nickel plating is available for corrosion resistance.
