SuperATV X300 Heavy-Duty Axles are stock-length replacement axles for the 2018-2021 Polaris RZR RS1 single-seat machine, sold front or rear. 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.
These rzr rs1 axles are built for the single-seater's speed. Each rzr rs1 axle is sold by position: the rzr rs1 rear axle or the rzr rs1 front axle. Polaris rzr rs1 axles from the factory share their weak points with the XP line, and these rs1 axles step up to 300M. If you want heavy duty rzr axles for the RS1, these x300 axles and superatv x300 axles are the rzr heavy duty axles with the 3-year warranty.

FAQ
Are these stock length?
Yes. These are stock-length axles for the RZR RS1.
Are they sold as a pair?
No. Each axle position is a separate part, sold individually. Order only the positions you need.
Are installation instructions available?
Yes. SuperATV's instructions are linked below.
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 RS1.
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 RS1 Driveline
If one RS1 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.
