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, œwhy 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. 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. 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?
