Demon Powersports Polaris RZR Pro R Xtreme Heavy Duty Axle Race Spec 300M (Rear)
Redesigned and re-engineered with a robust 300M aircraft-grade alloy shaft, these axles are built to flex and absorb impact, delivering unmatched durability and performance. Engineered to eliminate constant CV breakages and drivetrain failures, they are the perfect solution for vehicles with oversized tires, heavy-duty use, and off-road adventures.
Developed with a race-ready mindset and an eye on affordability, these axles offer ultimate performance without compromising on quality. The 300M steel used in these axles is a reinforced, high-strength version of 4340 chromoly, enhanced with Vanadium and increased Silicon content. Vanadium, commonly found in high-speed tool steels, boosts the alloy’s strength to exceptional levels, while the higher Silicon content improves hardness and resistance to high-temperature oxidation.
Designed for maximum longevity and resilience in extreme conditions, Demon Xtreme Race Spec Axles deliver a driving experience that combines strength, reliability, and excitement — all while staying true to the brand’s high-quality standards.

Demon Powersports (About)
Demon Powersports started with a passion for off-roading that’s probably a lot like yours. Demon spawned from our parent company, PDI International, and came about as a result of our love for the outdoors.
The team started developing products that would be applied to their own ATV / UTVs and to allow for easier travelling in all conditions. The idea was to help off-road enthusiasts with their desire to traverse through all terrains, which was the same need we had for better parts.
As the industry grew, so did Demon, it wasn’t just about our own, individual builds anymore, it was about improving parts of the machines that we needed to withstand the elements during a race.
