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 as tough as they come, and their proprietary high-temp grease can handle insane heat fluctuations without breaking down.
Industry-Leading High-Temp Performance
Assault’s high-temp boot grease is more important than you think. That’s because running at high speeds or high articulation angles causes tons of friction and heat buildup. Your stock grease can’t handle the heat and will break down in these conditions. This can lead to boot failure, CV failure, and catastrophic axle failure. Sand racers, rock crawlers, and trail riders can experience poor performance or busted axles from running normal axle grease. Phoenix Axles use high temp grease that doesn’t break down even when it gets hotter than hell.
Lab-Proven Performance
How good is a Phoenix Axle’s grease? It maxed out the test equipment at 586.5°F without breaking down, and OEM grease started breaking down at 365°F. So keep the needle pinned if you’re running Phoenix Axles—that’s what they’re made for.
Bigger CVs for Higher Articulation
Phoenix Axles are built with bigger CV joints so they can reach higher articulation angles without overheating. So run lifts and offset A-arms at full throttle on your RZR Pro XP without worrying about overheating. These axles are perfect for when your suspension drops through technical rock gardens too.
A Bigger Shaft for Extreme Strength
A premium Pro XP axle wouldn’t be premium if it didn’t increase the axle shaft size too. The bigger shaft and end-to-end chromoly construction ensure that it can survive heavy torque loads and low-talent moments that would wreck other axles.

Cute. Sturdy.
Color: Wooden, Size: Medium, Color: Wooden, Size: Medium
The wood was light but when I anchored them into the wall and they were very sturdy. Looked very cute on the wall. Affordable and easy to install if you’re handy.

Great besides the finish
Color: Wooden, Size: Medium
These are great. Only thing I wish it would’ve mentioned is they aren’t finished and can give you splinters unlike other shelves. But otherwise, they work for what they needed for, looks great, and easy to assemble for the price. They seem sturdy, but I don’t have much weight on it. Just something to keep from the kiddo

Small shelves, great value
Color: Wooden, Size: Medium
These shelves were great for an area out of the way, would not be perfect for everyone. Super sturdy and easy to install however the wood seems untreated and still a bit rough. The brackets don’t blend well and seem a bit out of place but these small and light shelves have been great at holding small items. I might not trust them with anything too heavy but they have held anything I tried. Only complaint is that they are a bit on the small side as far as depth goes. Other than that, they are awesome. If the brackets looked more sleek and the wood was stained it would be perfect for anywhere.
