Upgrade your full-size Jeep Wagoneer with the unmatched strength and smoothness of the RCV Ultimate Dana 44 CV Axle Set. These axles replace the factory 19-spline U-joint shafts with a high-strength constant velocity system that eliminates binding, increases articulation, and delivers twice the strength of OEM shafts.

RCVs CV design maintains full strength at every steering angle, unlike U-joints, which weaken significantly when turned. The result is smoother power delivery, improved reliability, and reduced breakage when wheeling with big tires, lockers, or increased engine torque.

Perfect for restored, lifted, or performance-built Wagoneers, these CV axles are strong, quiet, low maintenance.

IMPORTANT NOTE: All CVJ44OS axle kits require a 30 spline hub gear upgrade. RCV hub gears are compatible with Warn 20990 Premium Lockouts.

Includes:

• Left & right high-strength CV axle shafts
• 30 spline outer stubs
• SST seals & installation tool
• Synthetic moly grease
• Installation hardware
• Installation instructions
• Black oxide coating (standard)
• Optional nickel plating available

Tech Insight

Jeep Wagoneer Dana 44 front axles from 19801992 use a 19 spline outer shaft combined with U-joints, both of which become major limitations when upgrading tires, power, or locking differentials. RCV solves these issues by upgrading to a 30 spline CV joint system that maintains full rotational strength at any angle.

Benefits include: Smoother steering and articulation Reduced axle bind at full lock Dramatically improved torque capacity Increased reliability for lifted and off-road builds

This is one of the best durability upgrades you can perform on a full-size Jeep.
