Heat destroys axles. It really is that simple. When you push standard axles to their limit rock crawling, racing, or even trail riding, the grease heats up and eventually breaks down. Without grease, friction destroys your axles’ boots and CV joints, and can even lead to catastrophic axle failure. With Assault Industries’ Phoenix Axles, you get an industry-leading high-temp grease designed for the most aggressive rides. Push your RZR to its absolute limits without worrying about your axles thanks to Assault Industries.

  • High-temp grease prevents failure
  • Perfect for extreme applications like racing or rock crawling
  • Tested up to 586.4°F

Assault Industries set out to make the best axles in the industry. The result? Phoenix Axles. They’ve been tested up 586.4°F—as hot as the testing can get—without failure. That’s 61% hotter than OEM, which gave up at 365°F. Their one-of-a-kind grease blend truly delivers unbeatable heat resistance. If you’re looking for race-ready high-performance axles, your search is over. You won’t find a more premium axle. Whether you’re a professional hoping to win your next race or a hobbyist ready to take it to the next level, Phoenix Axles are the best you can get.

  • Easily outperforms OEM axle grease
  • Push your RZR harder for longer
  • CV Joints Made to Last

It takes more than just grease to make a premium axle. Assault Industries uses extremely durable CV joints on Phoenix Axles too. They’re made to support the most challenging technical rides. Even when you’re operating at high articulation angles, these axles will deliver 100% power without overheating. They’re perfect for high-speed runs across the dunes, expert-level rock crawling, and even trail riding.

  • Race-quality performance
  • Higher articulation than OEM
  • Larger Axle Shafts for Incredible Durability

Assault Industries didn’t skimp on the axle shafts either. Phoenix Axles are made with larger shafts than OEM and heat-treated chromoly steel. That means they’re insanely tough. Logs and boulders that would fold standard axles won’t put so much as a scratch in these. High-temp axle grease, high-performance CV joints, and muscular axle shafts make Phoenix Axles the only choice for extreme riders.
