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 rotationsomething no U-joint can match. The CV is 18% larger than previous Dana 44 designs and utilizes RCVs 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.

• Left & right high-strength CV axle shafts

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 accessno 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.
