Boss Bearing Diff Seal Kit Front Can-Am Maverick X3 Commander Defender 1000

The Boss Bearing 25-2121-5B Front Differential Seal Only Kit provides a targeted repair solution for Can-Am Maverick X3, Maverick Sport 1000R, Commander 1000R, and Defender 1000 owners dealing with differential seal wear or leaks — without the cost of replacing the bearings at the same time. This kit contains all the seals needed to fully re-seal the front differential. It's the right choice when an inspection confirms the bearings are still in good condition but the seals are dried out, cracked, or leaking. A leaking differential seal is more than an inconvenience — fluid loss leads to insufficient lubrication of the gears and bearings, causing heat buildup and accelerated wear that can turn a simple seal job into a full differential rebuild. By addressing seal failure early with this kit, you protect the bearings and gears that are still serviceable, extending the life of your front differential and keeping your repair cost as low as possible. A practical, cost-effective solution for any Can-Am owner who does their own maintenance or wants to minimize shop time.
