Fix Up Your Front Diff At some point, you will have put enough miles on your Polaris Sportsman or Scrambler that the front diff seals are gonna start leaking. It happens to the best of us, but if you ignore it, you can seriously damage your diff. Replace those stock seals with SuperATV™s Front Differential Bearing and Seal Kit. You get hub seals, an input seal, and an optional pinion bearing. Install them all and your diff will last for ages. Built Tough Your front diff sees some serious action whether it™s buried in mud or blasting through dunes. That™s why our seals are all high-quality double-lipped seals. They won™t let anything in. If you want to boost your drivetrain's strength and stability even more, add an pinion bearing. Add a Pinion Bearing You™ve got to face the facts: your leaky seals most likely damaged your pinion bearing as well. If you don™t want to blow another diff part, add our double-row angular contact bearing to the kit. It™s strong, it™s durable, and it™ll make sure everything runs smooth. KIT INCLUDES (2) 52 mm ID hub seals (2) 30 mm ID hub seals (1) Input shaft seal (1) Pinion bearing (optional)
