SuperATV Rhino 2.0 Big Lift Kit Axles are extended front and rear axles for the 2020+ Polaris RZR Pro XP and Pro XP 4 running SuperATV's RZR Pro XP 8" Lift Kit. SuperATV rates them nearly 2 times stronger than stock, with heat-treated 4340 chromoly from end to end, bigger shafts and CV joints, and 40°+ articulation angles.
These only work with SuperATV's Pro XP 8" Lift Kit. Choose Front or Rear; each axle is sold individually.
A Pro XP lift kit this tall changes the axle angles, so stock parts are the wrong length. If you run the Polaris RZR Pro XP lift kit from SuperATV, also called the RZR Pro XP 8 inch lift kit or the RZR Pro XP 4 lift kit on four-seaters, these RZR Pro XP lift kit axles are the matching parts. Pro XP lift kit axles are not the same as stock Polaris Pro XP axles; for a stock-height machine, see our standard listing. These are SuperATV's heavy duty RZR Pro XP axles for 8" of lift, and a direct RZR Pro XP axle replacement on a lifted machine.
