Polaris RZR S 900 Heavy Duty Billet Front Differential Gear Case



Polaris RZR S 900 Heavy Duty Billet Front Differential Gear Case

Why We Make It
The Polaris RZR S 900 is one of the best sport model RZRs ever made—that 60” of suspension takes corners faster, gets through whoops easier, and hits jumps harder, but don’t be surprised if you break your stock differential when you push the envelope that hard. SuperATV made its Heavy Duty Billet Front Differential Gear Case so that you can push your S 900 to its limits without ending up broken in the garage. Switch to a GDP differential housing and experience Gear Driven Performance on your machine!

The SuperATV difference
This diff housing is designed, engineered, and manufactured by the experts at SuperATV. That's why our front diff includes the magnet, wiring, seals, and the DU bushing all preinstalled to keep your down time to a minimum. Other guys make you reuse (and probably break) your stock magnet and wires. That’s a real pain. We also eliminated pain by using a bolt on cap instead of a snap ring to secure the pinion gear and seal. With the cap, you can remove your pinion gear and service your diff without destroying you oil seal every time. Our diff is easy to install and easy to service, and that means more time on the trail and less time in the garage.

The Best Diff in the Biz
Our front diff housing is made from 6061 billet aluminum which makes it 57% stronger than stock. We went all out and included helical inserts like those used by pro UTV racers. These helical inserts make it impossible for your mounting bolts to strip out or wallor out. Altogether that makes this one tough diff. Race, ride, and have fun with the pedal to the floor, you’re not about to do any damage to our diff.
