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.

Durable chew toy.
Color: Blue
My dog loves these. She chews on them a lot. She seems to like the different shapes. She is part Pit and an aggressive chewer. These chew toys last a long time. And I love the three pack so if we lose one, we always have a spare.

Decent durability for the price
Color: Blue
Bought a bunch of these for a dog shelter and have to say - decent for the price of you have aggressive chewers. All of the toys are still going 6+ months later, even with the strongest jawed pitty mix. Does get torn up at the ends but can easily be sanded down for a longer lasting toy, unlike some other hard toys with material not meant for sanding. The antler and ring seem to be favorites. The antler even has a divot so you can put soft treats in it or peanut butter and freeze it for a more interactive experience. Some came with a strong beef/liver smell but not overwhelming or off-putting. They are hefty without being too heavy, less likely to damage floors. Overall a good purchase

For aggressive chewers
Color: Blue
My pup is an aggressive chewer and these keep him occupied. He keeps coming back for them. Go to replaced old chew toys. Only issue is he leaves his toys everywhere and if you step on them. They are quite sharp
