The RCV Performance Ultimate Dana 44 CV Axles for the Jeep JL and JT Rubicon platform deliver unmatched strength, smoothness, and steering performance. These axles replace the OEM U-joint shafts with a high-strength constant velocity design that eliminates oscillation, crow-hop, and torque spikes caused by uneven U-joint power delivery.

RCV CVs maintain 100% strength at any steering angle up to 45°, thanks to six fully-engaged points of contact in every phase of rotation—something no U-joint can match. The CV is 18% larger than previous Dana 44 designs and utilizes RCV’s proven Dana 60-class architecture, offering twice the strength of OEM shafts while keeping the lighter weight and ground clearance advantages of a Dana 44.

This one piece FAD friendly design eliminates the factory disconnect coupler but retains full FAD module functionality. This means no warning lights and no reprogramming.

Tech Insight

This JL/JT-specific RCV CV is 18% larger than any previous Dana 44 CV and uses Dana 60 architecture, providing the strength of a full-float 1-ton front end while preserving the light weight and ground clearance of a Jeep platform.

Key performance advantages include:

  • 6 point CV contact = smooth, constant torque delivery 
  • Zero U-joint binding = no crow hop or vibration at full lock
  • Gun drilled outboards with grease port access—no disassembly required 
  • Significantly stronger than OEM Dana 60 U-joint shaft sets
  • Aircraft grade coupler materials 
  • Bronze FAD bushing replaces failure prone OEM plastic component

This upgrade is ideal for big-tire JL/JT builds looking to exceed Dana 60 performance without sacrificing clearance or weight.
