SuperATV Polaris RZR S 1000 Big Lift Heavy Duty Axles – X300

SuperATV’s Rhino X300 Big Lift Kit Axles for the Polaris RZR S 1000 change the game. With a 300M shaft that flexes to absorb force instead of breaking, you get CVs that don’t break and a drivetrain that won’t buckle. That means it’s built for big lifts, big tires, and big torque. We take it over the top by backing it with the industry-breaking 3-year 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.

We 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 make the X300’s signature flex possible. Without 300M, getting wild with a big lift would lead to broken components constantly.

Protects Your CVs and Drivetrain
On top of saving your CVs — the traditional axle weak spot — the X300’s flex also helps to protect your drivetrain. That last thing you want is diff to explode because your shaft is too strong. The X300 is smarter — it saves your axle, your diff, and your transmission when you hit it with a ton of torque.

Perfect for Big Tires and Big Lifts
How big can you go with a set of X300 axles installed? As big as you want. Big lifts and big tires are what X300 is all about. If you have trouble keep your big custom build in one piece, 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.
