Built Tough Our Polaris General and General 4-seater Heavy-Duty Front Differential Gear Case is designed, engineered, and manufactured by our expert team at¯SuperATV.¯It uses 6061 aluminum available in both cast and billet and includes¯steel helical inserts to make it as strong as possible. Our differential gear case housing comes with the magnet and wiring preinstalled. Other guys make you install (and likely damage) your magnet and wiring yourself. SuperATV does the work for you. We also include all seals and bushings pre-installed, and we use a bolt on cap to retain the pinion bearing instead of a snap ring. This case does NOT include any internal gears, but we make it easy to just drop in the internals from your stock differential and you™re good to go! We made it as easy as possible so you can get your machine up and running again in no time.¯ The Best Diff You Can Get Our front differential gear case is available as cast or billet.¯Our billet aluminum gear case is thicker, denser, and 57% stronger than a stock housing. Our differential housing will take the abuse even when you add massive tires, a lift kit, and a heavy-duty prop shaft that all puts extra stress on your diff. The strength of our design doesn't just come from the best materials”we also utilize steel helical inserts for the mounting points just like those used by pro UTV racers. Helical inserts reinforce the threads on your housing so that no matter what jumps, whoops, and obstacles you hit, your mounting points will never pull out of your differential. And it™s backed by a Lifetime Warranty”you get the strongest differential housing around and it™s backed by SuperATV™s best guarantee!¯ The SuperATV Difference The Polaris General and the General 4-seater are big machines, and that puts a lot of stress on your stock differential. That makes your OEM diff at even greater risk for failure. Upgrade to SuperATV™s heavy duty billet front differential gear case and keep your drivetrain as tough as the rest of your General.
