Polaris ATV Front Differential Bearing and Seal Kit | SuperATV

At some point, you will have put enough miles on your Polaris Sportsman or Scrambler that the front diff seals are gonna start leaking. 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 its buried in mud or blasting through dunes. That's why SuperATV 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 SuperATV double-row angular contact bearing to the kit. It's strong, its durable, and it'll make sure everything runs smooth.

Upgrade to SuperATV Hub Bearing Kit for More Durability

If you want to really beef up your front diff, upgrade to SuperATV hub bearing kit. It includes hub bearings to keep your axle hubs running true. It also includes a return spring pin, the pinion bearing, and all other seals apart from the 30 mm ID hub seals. It's a huge upgrade.
