Polaris RZR 1000xp Xtreme Heavy Duty Axle *Race Spec 300M

Demon Powersports Axle
Our strongest axle to date — this Xtreme Heavy Duty Race Spec axle brings unmatched durability and performance to demanding off-road adventures.
Redesigned and re-engineered with a robust 300M shaft that flexes and absorbs force, it dramatically reduces CV breakages and drivetrain failures so you can push harder with confidence. Built for heavy lifting, oversized tires, and race-ready applications, it delivers reliable strength without burning a hole in your pocket.
What sets the 300M steel apart is its composition. This aircraft-grade alloy is a reinforced evolution of 4340 chromoly, enhanced with Vanadium and higher Silicon content. Vanadium—common in high-speed tool steels—elevates tensile strength and toughness, while increased Silicon improves hardness and resistance to high-temperature oxidation. The result is an axle designed to withstand the harshest conditions and last longer under extreme loads.
