Polaris RZR XP 900 Heavy Duty Billet Front Differential Gear Case

Why We Make It
When you got for a ride on your Polaris RZR XP 900, you want to get dirty and have fun—you don’t want to blow your diff. That’s why SuperATV made its Heavy Duty Billet Front Differential Gear Case. It’s tough as nails and 57% stronger than your OE diff, which means this diff will keep your drive train together no matter how much riding or partying you do. Switch to a GDP differential housing and experience Gear Driven Performance on your machine!

The SuperATV difference
Our replacement front diff gear case is designed, engineered, and manufactured by the experts right here at SuperATV. That's why it comes with the magnet, wiring, seals and DU bushing preinstalled right out of the box, and you can get back to riding as quickly as possible. Some other guys make you reuse your stock parts and install them your self—a tedious process that usually leads to damage. We also made our diff easier to service by using a bolt on cap to secure the pinion gear, bearing, and oil seal which means you can disassemble you diff without destroying your seals.

The Strongest Diff Around
Our front diff housing is made of 6061 billet aluminum which is 57% stronger than the OEM front diff housing. We wanted even more bulletproof performance, so we include helical inserts in every diff. these inserts make it impossible for the mounting bolts to pull out or wallor out. That makes this diff capable of handling every high-torque mud hole and hardcore hill climb you come across.
