Polaris RZR XP 1000 MAS-223 Phoenix Axle



Polaris RZR XP 1000 MAS-223 Phoenix Axle

Innovative High-Temp Grease Changes the Game

You’ve been planning this trip to the dunes for months and you’re going to make the most of it, come hell or high water! You’re way more likely to face a broken axle due to overheating than high water out in the sand—but not with Assault Industries' MAS-223 Phoenix Axles on your Polaris RZR XP 1000. Thanks to Assault’s industry-leading high-temp grease blend, these UTV axles are ready to dominate the desert.

  • Proprietary high-temp grease blend for unmatched performance
  • Incredibly high CV angles
  • 4340 chromoly steel construction
  • Increased shaft size

Heat Won’t Destroy These Axles

Heat will destroy standard axles—that’s a fact. The extreme conditions in the desert or pushing them to their limits racing, trail riding, or rock crawling will break down the grease inside. Without grease, friction builds up and ruins your boots and CV joints, or causes catastrophic axle failure.

Tested up to 586.4°F

We’re confident in these axles because Assault Industries has proven what they’re capable of. They’ve been tested up to 586.4°F—as hot as the testing can get—and didn’t quit. That’s 61% hotter than OEM, which gave up at 365°F.

Beefed-up CV Joints for Impressive Performance

These axles are more than just innovative, high-temp grease. Assault designed Phoenix Axles with durable CV joints too. They deliver 100% power even at high articulation for impressive performance on the trickiest rides.

Chromoly Axle Shafts Resist Damage

Assault didn’t stop with the CV joints. Phoenix Axles are equipped with muscular axle shafts too. They’re bigger than OEM and built with heat-treated chromoly steel for unbeatable strength. These premium axles can handle boulders and logs that would have crumpled your OEM axles.


  • Proprietary high-temp grease blend perfect for aggressive riding
  • Reduced friction prevents heat buildup
  • Grease is virtually waterproof
  • High pressure tolerance for extreme
