Assault Industries Mas-223 Phoenix Axle Polaris RZR Turbo R



Don’t Back Down from Extreme Conditions

When the sun’s high and the temps are hitting 110°, most riders will pack up and head back to camp. Nobody wants to risk their axles overheating. But you don’t have to back down! You’ve got Assault Industries’ MAS-223 Phoenix Axles installed on your Polaris RZR Turbo R. Assault’s innovative grease blend gives you impressive protection from high temperatures that could destroy your axles. Plus they’re bigger than stock and the CVs can handle high articulation angles.

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

Heat kills more axles than anything else. How? Running at high speeds or high articulation angles causes ordinary grease to break down. When the grease breaks down, friction tears your axles apart through boot failure, CV failure, or even catastrophic axle failures. These kinds of heat-related failures can happen to anyone, whether you’re racing on scorching hot dunes, climbing rock walls, or navigating complicated trails. Assault Industries’ Phoenix Axles use a premium high-temperature grease blend to give you unparalleled performance in the most extreme riding conditions.

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

These are the best axles you can get—period. How do we know? The’ve been tested! Assault’s industry-leading high-temp grease can withstand temperatures up to 586.4°F—as hot as the testing can get—without failure. That’s 61% hotter than OEM Polaris axle grease! (For reference, OEM gave out at just 365°F.) Thanks to Assault Industries’ innovative high-temp grease, these axles offer absolutely incredible performance. From hobby riders to professionals, there’s no better choice than Phoenix Axles for your RZR.
