RCV 35-Spline Dana 44 CV Axle Set for Jeep TJ & LJ Rubicon w/ ARB Locker
SKU: CVJ44-35T
If your TJ or LJ Rubicon is running the modern 35-spline ARB two piece locker, this is the correct RCV axle upgrade. The factory style U-joint shafts simply cannot handle the torque output of a 35 spline locker, especially with big tires, deep gears, or high horsepower builds.
The RCV Ultimate Dana 44 CV Axle Set replaces those weak points with a high strength constant velocity design proven to be twice as strong as OEM. Unlike traditional U-joints, RCV CV joints maintain full strength and smooth rotation at every steering angle and eliminates binding, chatter, and steering angle failures.
These axles are engineered specifically to the adjusted length requirements of the modern two piece 35-spline ARB locker and deliver unmatched durability on-road or off-road. Smooth, quiet, and low maintenance.

Tech Insight
Upgrading the Dana 44 to a 35 spline ARB locker massively increases torque capacity—but the factory style U-joint shafts become the immediate weak link. RCV solves this by using a constant velocity joint that maintains full strength at any angle, dramatically reducing shaft failures when locked in or turning under load.
These adjusted length 35 spline inner shafts are engineered specifically for the modern two piece ARB locker, ensuring perfect fitment and maximum drivetrain strength for aggressive TJ/LJ builds.
