Setting the Bar for Extreme Axles
Your Pro XP puts out a ton of power, and when you put the pedal down, you’ll send your axle temps sky high. If you’re a little off camber, those temps can lead to catastrophic axle failure fast. That’s where Assault Industries' MAS-223 Phoenix Axle comes in. They’re built for extreme performance with proprietary high-temp grease that can handle intense heat fluctuations without breaking down.
Industry-Leading High-Temp Performance
Running at high speeds or high articulation angles creates friction and heat buildup. Standard axle grease can break down in these conditions, which can lead to boot failure, CV failure, and catastrophic axle failure. Phoenix Axles use high-temp grease designed to keep performing under extreme heat.
Lab-Proven Performance
In testing, the Phoenix Axle grease maxed out the test equipment at 586.5°F without breaking down, while OEM grease started breaking down at 365°F.
Bigger CVs for Higher Articulation
Phoenix Axles are built with larger CV joints to reach higher articulation angles without overheating. They’re ideal for lifted setups, offset A-arms, and demanding terrain like technical rock gardens.
A Bigger Shaft for Extreme Strength
The larger shaft and end-to-end chromoly construction help the axle survive heavy torque loads and tough riding conditions.
