Rhino X300 Axles Change the Game
SuperATV’s Rhino X300
axles for the Polaris RZR XP Turbo change the game. With a 300M shaft that
flexes to absorb force instead of breaking, you get CV’s that don’t break, a
drivetrain that won’t buckle, and the ability to go on bigger, meaner rides.
We take it over the top by backing it with a 3-year warranty — the industry’s
best axle warranty.

It’s All About the Flex
X300 is about more than brute strength, it’s about flex. When X300 gets hit
with a torque load that would break other axles, the 300M shaft twists until
the load is gone then returns to its original position. Our unique Flexshaft™
technology relieves much of the stress that would be transferred to your CVs
and differential with other axles. The result is less wear and tear on much
more valuable drivetrain parts.

make X300 with super-tough 300M alloy steel. 300M is an aircraft-grade alloy
utilized for its high strength and higher silicon composition, along with its
inclusion of vanadium. These unique properties of 300M combined with our
specific design makes the X300’s signature flex possible. It makes doing
anything you want with wild vehicle modifications possible.

Perfect for Big Tires and Big Rides
What can your UTV
get away with when your axle saves your from yourself with a good flex? Flex
means riding harder with bigger tires on tougher trail without breaking
anything. If you’re tired of breaking stuff, X300 is for you.

3-Year Warranty
We’re not done yet, X300 comes with a
3-year warranty! That’s the industry’s best warranty for any axle anywhere.
That’s how confident we are in our X300 Axles.
