Get Your RS1 Race-Ready You want to tear up the sand
with the big boys—but those OEM axles just aren’t going to cut it. You need
the best of the best if you want to turn your Polaris RZR RS1 into a real
racing machine. That’s where Assault Industries' MAS-223 Phoenix Axles come
in. They’re designed for the most intense riders and the most extreme
conditions. Thanks to Assault’s proprietary high-temp grease blend and race-
ready axle construction, Phoenix Axles dominate the competition.
- Proprietary high-temp grease blend for unmatched performance
- Incredibly high CV angles
- 4340 chromoly steel construction
- Increased shaft size
Built to Withstand Face-
Melting Heat! Here’s a simple fact—heat kills axles. And it
doesn’t matter if it’s the constant heat of the desert or the heat generated
by pushing your axles to their limits. As temperatures rise, the axle grease
breaks down. Without grease, you get friction. That friction ruins your boots
and CV joints, and can even cause catastrophic axle failure. Assault invented
a premium axle grease blend that won’t break down even in the most extreme
conditions. That’s right—you can push your RS1 to its absolute limits without
breaking down thanks to Assault’s revolutionary Phoenix Axles.
Tested up to 586.4°F Phoenix Axles really walk the walk.
They were tested up to 586.4°F—as hot as the testing can get—without failure.
That’s 61% hotter than the OEM grease, which failed at 365°F. That means it
could literally be hot enough to fry an egg outside and these axles won’t even
flinch. No standard axles can compete with that kind of premium performance.
If you’re looking to race with the professionals (or maybe you ARE a
professional), you won’t find better performance axles for your RS1.
The Most Reliable CV Joints Assault knows that it takes
more than industry-leading high-temp grease to make the world’s best racing
axles. They upped the game when it comes to the CV joints too. These CV joints
are built for those complex, tricky rides that require high articulation
angles. Phoenix Axles deliver 100% power no matter how weird and wild the ride
gets—and they won’t overheat under stress. Whether you’re tearing up the
trail, racing on sand, or clambering on the rocks, these CV joints can handle
it.
Beefy Chromoly Axle Shaft Of course
Assault didn’t skimp on the axle shafts either. Phoenix Axles have larger
shafts than OEM. Plus they’re made with heat-treated chromoly steel. Combined,
that makes them nearly unbreakable. No boulder or log is going to take these
axles out! Beefy axle shafts, muscular CV joints, and unstoppable grease make
Phoenix Axles the world’s leading performance axle. Would you expect any less
from Assault Industries?
