Polaris RZR Complete Differential

Product Description
<strong>The Only Aftermarket Polaris® Differential </strong> <br /> 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. <br /> <br /> <strong>Why SuperATV's Differential is Better</strong> <br /> 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. <br /> <br /> <strong>Hobbed Gears Are Quiet and Smooth</strong> <br /> 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. <br /> <br /> <strong>Stronger Mounting</strong> <br /> 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. <br /> <br /> <strong>Upgrade to Billet</strong> <br /> 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. <br /> <br /> <strong>Install with Confidence</strong> <br /> 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.

A complete differential replacement restores proper power delivery and locking function to the front wheels. </p> </div> <div class="faq-item"> <strong>Will this complete differential fit my specific Polaris RZR model?</strong> <p> This differential is designed to fit a wide range of Polaris RZR models, including XP 1000, XP Turbo, S, Trail, and older 800 and 900 models. Fitment is based on OEM part number, so matching your factory number ensures correct compatibility. </p> </div> <div class="faq-item"> <strong>How is the SuperATV complete differential different from an OEM replacement?</strong> <p> We took Polaris’ original design and strengthened it with thicker gears, reinforced mounting points, and an upgraded aluminum case. It delivers stock‑like performance with significantly improved durability in high‑stress riding conditions. </p> </div> <div class="faq-item"> <strong>Does the SuperATV RZR differential come fully assembled?</strong> <p> Yes, the differential ships completely assembled and ready to install, which eliminates the need for internal setup or special tools. You only need to add gear oil before putting it back into service. </p> </div> <div class="faq-item"> <strong>What materials are used to make this differential stronger?</strong> <p> The differential features a heavy‑duty cast or billet aluminum housing and uses a 7075‑T6 aircraft‑grade aluminum Sprague carrier for maximum strength. These materials are chosen specifically to withstand repeated AWD engagements and high torque loads. </p> </div> <div class="faq-item"> <strong>How does this differential improve reliability during aggressive riding?</strong> <p> We reinforced known weak points by thickening the pinion tube, strengthening mounting locations, and using helical inserts to prevent bolt pull‑out. Hobbed ring and pinion gears also run smoother and quieter while increasing long‑term durability. </p> </div> <div class="faq-item"> <strong>Is installation difficult for a complete RZR differential?</strong> <p> Installation is a direct bolt‑in replacement and can be completed with standard hand tools by an experienced DIY installer. We provide detailed installation instructions to guide you through each step. </p> </div> <div class="faq-item"> <strong>Can I choose between cast and billet differential housings?</strong> <p> Yes, this differential is available with either a cast aluminum case for dependable strength or a billet aluminum case for maximum durability and precision.
