Manufactured in the U.S. using only high-strength chromoly materials, RCV Performance Ultimate 30 spline CV Axle set simply replaces your weak Toyota axle shafts with a new high-strength design. The factory axles were designed with 30 splines at the differential, and neck down to 27 Spline at the CV creating a common failure point. This axle set upgrades the weak 27 splines at the CV to a 300M 30 spline race eliminating this issue. Tests prove Ultimate CV Axles to be twice as strong as OEM shafts, and they're just as tough at a straight angle as they are at extreme angles. 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.Axle set includes right and left inner axle shafts -2 pregreased CV joints. Black oxide coating is standard, optional nickel plating is available for extra corrosion resistance in salty environments. We can accommodate custom length inner shafts - contact us for details -pricing, or use our Custom Axle Configuration Form.For a limited time, your axle kit will come with a free hub gear set included! 4340 Replacement Inner Hub Gear Set Applications: Land Cruiser II, Bundera, Prado 70 Series LJ70LJ71LJ73LJ74LJ78RJ70RJ73RJ78KZJ70KZJ71KZJ77
