The Only Aftermarket Polaris® Differential
again, SuperATV brings you a product you can’t get anywhere else. SuperATV’s
RZR Complete Differential is the only aftermarket Polaris diff on the market.
Some of you may be wondering, “why not just reorder the OEM diff?” The answer
is simple—we’ve taken Polaris’ already proven design and made it better. And
by better, we mean stronger. SuperATV’s Differential is designed to deliver
power to your front wheels and lock when you want it to. It has the
performance you love on your stock RZR with the strength you expect from
SuperATV. It’s not just an OEM replacement differential, it’s Built for

Why SuperATV’s Differential is Better

You don’t just get replacement internals for your diff—we give you the
complete differential all assembled and ready to install. You get a whole new
heavy-duty cast or billet aluminum case, thicker gears, bushings, seals, hubs,
Sprague, armature, and wiring. To take our differential to the next level, we
use 7075-T6 aircraft grade aluminum for our Sprague carrier to give maximum
strength and durability. That means our differential can endure ride after
ride of hard differential lock engagements without failing—which also means,
you won’t have to worry about getting a replacement anytime soon. We have
drastically improved the components prone to failure and wrapped them in a
stronger case.

Stronger Mounting
beefed up our differential case by using helical inserts in the mounting
threads. These inserts make it virtually impossible for the mounting bolts to
wallow out or pull out over time. We also added additional material to the
mounting locations. OEM has feet-like mounting locations, while ours mounts to
a single block built into the body of the diff. We also thickened the pinion
gear tube to make sure it can stand up to every bump, jar, and torque load.
Plus, we make it easy on you. We use a bolt-on cap to retain the pinion
bearing instead of a snap ring. That means you can service your pinion gear
without destroying your seal.

Upgrade to Billet

Upgrade to our billet aluminum differential case for ultimate strength
and performance. Billet is denser, stronger, and less porous than cast, plus
it looks really stinking good. If you’re a pedal down, no holds barred kind of
rider that chews up stock differentials, you need a stronger billet diff.

Install with Confidence
What does all this
mean for you? You can hit all those big jumps you’re scared to hit now and
never turn back. If you’re here because you blew up your stock diff, it’s time
to upgrade to SuperATV’s Complete Differential. You get a preassembled, bolt-
on ready differential for less than OEM price. What’s not to love?
