The RCV Performance Ultimate CV Axles with 300M inner axle shafts for Jeep JL & JT Rubicon Dana 44 provide unmatched strength and smoothness you can feel. The RCVs simply replace your OEM Jeep JL or JT axle shafts with a high-strength constant velocity design. Our CVs eliminate oscillation and "crow hop" caused by the uneven power delivery of a u-joint axle. The RCV CVs provide 6 points of fully-engaged contact throughout any angle up to 45 degrees, providing 100% strength even when the steering is turned to lock.
