We make out billet front differential housing because you demand performance, and when you’re cruising solo on a Polaris ACE, you need the most reliable parts on the market. SuperATV’s Heavy Duty Billet Front Differential Gear Case is designed to make your Ace bulletproof and let your ride where you never could before. Switch to a GDP differential housing and experience Gear Driven Performance on your machine!

The SuperATV difference
This replacement front diff is designed, engineered, and manufactured by the experts at SuperATV, so you get more than just a replacement diff housing. You also get the magnet, wiring, seals, and the DU bushing all preinstalled. That means you just drop in your OE internals and you’re good to go. No need to wreck your seals and magnet trying to transfer them from your old case. We use a bolt on cap to secure the pinion gear and seal so you can service your diff without destroying a seal every time. Easier service means better maintenance, and year after year of perfect performance.

The Strongest Diff Around
Our differential housing is made of 6061 billet aluminum which means it’s 57% stronger than your OEM diff. Couple that with the included helical inserts and you’ve got a 100% bulletproof differential. These helical inserts prevent your mounting bolts from pulling out or walloring out over time. That means you can push your ACE harder than you ever have before and never worry about wearing out your diff.
