If your Jeep JK Rubicon is running a non-stock carrier or an aftermarket heavy-duty housing such as the TeraFlex JK Tera44, your factory length axle shafts will no longer fit. The RCV Ultimate Dana 44 CV Axle Set is designed specifically for Rubicon builds using aftermarket 30 spline carriers and updated carrier offsets.

These RCV axle shafts replace the OEM U-joint design with a high strength constant velocity joint that remains just as strong at full steering lock as it is when straight. The result is smoother engagement, increased traction, and dramatically reduced binding compared to standard U-joints.

Engineered for big tire setups, higher horsepower builds, and aggressive wheeling, these axles deliver twice the strength of OEM and require minimal maintenanceall backed by RCVs No Questions Asked Limited Lifetime Warranty.

• Left & right non-stock carrier length CV axle shafts
• 32 spline outer stubs
• SST seals & installation tool
• Installation hardware

Tech Insight

Aftermarket housings and non-stock carriers often shift the carriers position inside the housing, requiring custom length inner axle shafts. OEM shafts or standard RCV JK Rubicon shafts will not fit correctly in these setups.

This RCV kit corrects those lengths while upgrading the entire shaft assembly to a constant velocity design that eliminates binding and delivers full strength at all steering angles. Perfect for high load rock crawling, 3740 tires, and high-performance Rubicon builds running non-stock geometry.
