ARB’s air locker upgrade dramatically increases traction, but it also increases stress on the front axle shaft system, especially at full steering lock. RCV solves this by eliminating the weak U-joint entirely. The Ultimate CV design maintains full rotational strength at any angle, reducing breakage when lockers engage, when running technical terrain, or when tires load hard under throttle.
The 30 spline ARB matched inner shafts and 32 spline outer stubs deliver a balanced, stronger than stock torque path that unlocks the full capability of your upgraded differential.
