The Only Aftermarket Polaris® Differential Built for Superior Strength and Performance

Upgrade your Polaris RZR with the SuperATV Complete Differential—the only fully assembled aftermarket differential designed to outperform OEM in every way. Engineered for riders who demand extreme reliability and durability, this differential delivers the seamless power transfer, locking capability, and long-lasting strength your RZR deserves. Whether you’re trail riding, rock crawling, or pushing full throttle through mud and sand, SuperATV’s differential ensures consistent performance and confidence on every ride.

Engineered to Outlast OEM

SuperATV takes Polaris’ proven design and strengthens it with premium materials and advanced engineering. The differential features a heavy-duty cast or billet aluminum case, precision-cut hobbed gears, and a 7075-T6 aircraft-grade aluminum Sprague carrier for unbeatable resilience. Each unit arrives preassembled and ready to install, giving you the convenience of a plug-and-play upgrade that’s stronger than stock and priced competitively. With thicker gears, reinforced bushings, improved seals, and a robust armature plate, this differential is built to handle aggressive torque loads and demanding terrain without compromise.

Quiet, Smooth, and Reliable

The precision hobbed ring and pinion gears deliver smoother engagement, reduced vibration, and quieter operation compared to traditional gear cuts. This means a more comfortable ride and enhanced longevity of internal components. Combined with helical inserts in the mounting threads and a thickened pinion gear tube, every aspect of this differential is optimized for strength and serviceability. The bolt-on cap design allows quick access to the pinion bearing, simplifying maintenance and minimizing downtime.

Choose Cast or Billet

Available in your choice of cast aluminum for rugged dependability or billet aluminum for ultimate strength and precision fit, this differential is ready for riders who push limits. Billet construction offers a denser, stronger structure, perfect for high-horsepower builds or extreme riding conditions. Both options are crafted to deliver superior performance and a perfect fit for your Polaris RZR.

Key Features:

  • Fully assembled and ready to install—just add oil
  • Heavy-duty cast or billet aluminum housing
  • 7075-T6 aircraft-grade aluminum Sprague carrier
  • Hob-cut ring and pinion gears for smooth, quiet performance
  • Reinforced pinion gear tube with 3/8" thick walls
  • Stronger mounting points with additional material and helical inserts
  • Easy service bolt-on cap for pinion gear access
  • Complete assembly includes hubs, seals, armature plate, wiring, and hardware
  • Designed to match OEM performance with enhanced durability

When it’s time to replace your stock Polaris RZR differential, don’t settle for less. The SuperATV Complete Differential gives you superior construction, preassembled convenience, and the confidence to ride harder, longer, and smarter. Built for battle and engineered to perform, this is the ultimate upgrade for serious riders who expect the best from their machine.
