FAQ
Do they fit the Pro XP 4?
Yes. SuperATV lists the 2020+ RZR Pro XP and RZR Pro XP 4.
Are they sold as a pair?
No. Each axle position is a separate part, sold individually. Order only the positions you need.
Are these stock length?
Yes. These are stock-length axles for machines without a lift or long-travel kit.
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 Pro XP.
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 Pro XP Driveline
If one Pro XP 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.
