If youve stepped up your Dana 30 with a 30-spline aftermarket differential, this is the axle set built to match it. The RCV Performance Ultimate CV Axle Set replaces the factory 27-spline U-joint shafts with a high strength 30 spline CV design engineered to handle big tires, big power, and hard off-road use.
RCVs constant velocity construction eliminates U-joint binding and delivers smooth, consistent power where stock U-joints are at their weakest. Testing shows these Ultimate CV Axles are twice as strong as OEM, giving your upgraded Super 30 all the reliability it deserves.

Tech Insight
A Super 30 upgrade adds serious strength to the Dana 30, but the factory 27 spline U-joint shafts quickly become the weak link. RCVs 30 spline Ultimate CV design balances the system by eliminating the binding, chatter, and angle induced failures common with U-joints.
The CV joint remains equally strong at all steering angles, which means better traction, smoother feel, and reduced risk of breaking a shaft when youre locked in and turned full tilt. For Jeeps running lockers, 35s or under, or aggressive off-road terrain, this is the axle upgrade that makes your 30 spline diff truly worth it.
