SuperATV X300 Big Lift Kit Axles are heavy-duty replacement axles for the Polaris RZR 900, RZR S 900, RZR 4 900, RZR S4 900 and RZR 900 XC running a 7-10 inch lift kit. They use a 300M alloy steel shaft with Flexshaft technology, CV components made of 300M and 4340 alloy steel, and a 3-year warranty.
Choose Front or Rear. Each axle is sold individually and is built at the length a lifted machine needs.
These rzr 900 lift kit axles are for lifted machines. Stock rzr 900 axles are not sized for the angle, so each rzr 900 axle here is built for a 7-10 inch lift, including rzr 900s axles on the S. Order the rzr 900 rear axle or the front; the rzr 900s rear axle is the same part. Among rzr lift kit axles and big lift kit axles, these x300 axles are the heavy duty rzr axles SuperATV builds.

FAQ
Do they fit the RZR XP 900?
No. SuperATV lists the RZR 900, S 900, 4 900, S4 900 and 900 XC.
What lift are they built for?
SuperATV lists these for a 7-10 inch lift kit.
Are they sold as a pair?
No. Each axle position is a separate part, sold individually. Order only the positions you need.
How do X300 axles compare to Rhino 2.0?
X300 uses a 300M alloy steel shaft and 300M/4340 CV components with a 3-year warranty. Rhino 2.0 uses 4340 chromoly with an 18-month warranty and costs less. We list both for the RZR 900.
Can I rebuild an X300 axle later?
Yes. We stock SuperATV X300 boot kits and X300 CV joint kits matched to X300 part numbers, so one worn end does not mean a whole new axle.
What warranty do X300 axles carry?
SuperATV backs each X300 axle with a 3-year warranty against manufacturing defects to the original purchaser.
Why SuperATV X300
SuperATV designs, engineers and tests its X300 axles in-house as the step above its Rhino 2.0 line. X300 swaps Rhino 2.0's 4340 chromoly shaft for 300M alloy steel and builds the CVs from 300M and 4340, and every X300 axle carries a 3-year warranty against manufacturing defects to the original purchaser, double the 18 months on Rhino 2.0.
Complete Your RZR 900 Driveline
If one RZR 900 axle has failed, check the others for the same wear before you ride again. Pair your X300 axles with the matching X300 boot or CV joint kit for future service, and confirm your year and model against the fitment list.
