Polaris RZR 800 Heavy Duty Billet Front Differential Gear Case



Polaris RZR 800 Heavy Duty Billet Front Differential Gear Case

Why We Make It
There are a ton of Polaris RZR 800 seaters on out there, but we still want to push them as hard as ever—that’s why SuperATV makes a Heavy Duty Billet Front Differential Gear Case. The machine may be getting old, but with a bullet proof differential installed, your drive train will be running smooth for years to come. Switch to a GDP differential housing and experience Gear Driven Performance on your machine!

The SuperATV difference
Our differential housing is designed, engineered, and manufactured by our expert team at SuperATV so we made sure it comes with everything you need. The magnet comes built in and the kit includes, all wiring, seals, and the DU bushing preinstalled. Other guys make you install it all yourself or even reuse your old seals and magnets—good luck not breaking a wire or tearing a seal. We make it easy, just drop in the internals from your stock differential and you’re good to go! We hate spending time in the garage as much as you do. Your RZR 800 might be old, but it’s not a project yet.

The Best Diff You Can Get
Our front differential gear case is made of 6061 billet aluminum which makes it 57% stronger than the cast aluminum in your stock differential. We took strength and longevity further by including helical inserts in the mounting threads just like the ones pro UTV racers use. These helical inserts lock your mounting bolts in place and keep them from walloring out the threads over time. They extend the life of your diff by thousands of miles. So ride hard every day—hit the biggest jumps, whoops, and hills. Do whatever you want on your RZR 800. No matter what you do, our billet differential gear case won’t break.
