Get a Better Differential Housing
When you’re flying solo on your Polaris ACE, you have absolute freedom. That all comes crashing down when your front differential cracks open and you’re left without four-wheel drive. Fix your front differential problems with SuperATV’s Polaris ACE Heavy-Duty Front Differential Gear Case. This housing is thicker and stronger to keep all your internals running true.
Built for Strength
Thicker walls and stronger mounting make this housing a beast. It can stand up to rough engagements that would crack a stock housing. Steel helical inserts for the mounting threads survive any amount of vibration and shock you throw at them. Plus, you get to choose between cast and billet aluminum to get the ultimate strength and shine you crave.
Preassembled for Easy Installation
We install the seals and bushings along with the magnet and wiring for you because we know it’s a huge pain in the butt. All you have to do is open the box, drop in your internals, and mount it to the machine. You’ll be riding before you know it.
Kit Includes:
