The Only Aftermarket Polaris® Differential
Once 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 Battle.
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.
Hobbed Gears Are Quiet and Smooth
Our complete Polaris RZR front differential uses hobbed gears for the ring and pinion gears. Why does that matter? Hobbed gears are cut and finished with perfect precision you can’t get with other gear-making methods. The result is perfectly mating gear teeth that run smooth with almost no noise or vibration. It makes your ride more comfortable and boosts long-term durability.
Stronger Mounting
We’ve 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.
