Upgrade your Jeep JK Rubicon the right way with the RCV Performance Ultimate Dana 44 CV Axle Set. These axles replace the factory U-joint shafts with a high strength constant velocity design that delivers twice the strength of OEM JK axle shafts, and they maintain that strength at extreme steering angles, where U-joints are weakest.

The RCV CV joint eliminates binding, increases articulation, improves traction, and provides smoother power transfer whether you're crawling, trail riding, or hitting high speed rough terrain. Even with big tires and serious horsepower, these axles stay quiet, smooth, and reliable.

Includes:

  • Left & right Ultimate Dana 44 CV axle shafts
  • SST seals & installation tool
  • Synthetic moly grease

  • Installation instructions
  • Black oxide coating (standard)

Tech Insight

The factory JK Rubicon Dana 44 U-joint shafts are a known weak point, especially when paired with lockers, 37–40 tires, or aggressive terrain. RCV solves this by replacing U-joints with a constant velocity design offering full rotational strength at all steering angles.

This allows your JK to turn harder, climb smoother, and take shock loads that would destroy a traditional axle shaft. With RCV’s sealed bootless design, maintenance stays minimal and performance stays consistent for the life of the vehicle.
