Forget High CV Temps—Phoenix Dominates
Want the best damn high-speed, rock-crawling, and racing axle on the planet? Assault Industries' MAS-223 Phoenix Axle is it. Install a set on your Polaris RZR Pro XP for industry-leading performance. Phoenix Axles' all-chromoly construction and proprietary high-temp grease change the game—it can handle extreme rides and ultra-high temps that would destroy any other axle.
Proprietary high-temp grease blend for unmatched performance
Incredibly high CV angles
4340 chromoly steel construction
Increased shaft size
Cutting-Edge Boot Grease
Assault Industries' cutting-edge high-temp grease raises the bar. When you ride flat out through the desert or constantly throttle when your suspension is dropped in rock gardens, your CVs get hot and typical grease will overheat. This can cause boot failure, CV failure, and catastrophic axle failure. Sand racers, rock crawlers, and even trail riders can experience poor performance or busted axles from the negative effects of your average grease. Our premium blend doesn’t overheat or break down, so you can go as hard as possible.
Lab-Proven High Temp Performance
Our lab tests prove that our high-temp grease blows OEM grease out of the water. It maxed out the testing equipment at 586.4°F without losing any viscosity or effectiveness. OEM grease was useless at 365°F. That’s what makes Phoenix Axles perfect for pushing your RZR Pro XP to the max whether you’re gunning for the top spot on the podium or just cruising through dunes.
Maximized CV Joints for Smooth Operation
Assault Industries made these CV joints as large as possible to maximize axle articulation. You can run a lift kit or offset A-arms through rock gardens all day long without causing binding or overheating. They’re Pro XP axles that let you push the envelope any way you ride.
A Stronger Axle Shaft
Phoenix Axles are made with end-to-end chromoly steel and use a larger diameter axle shaft to improve overall durability. They’re built for big hits, massive torques, and wild rides—anything you can throw at them. These aren’t just premium axles—they’re game changers.
