Boss Bearing 25-2121B Differential Bearing Seal Kit Front Can-Am

This Front Differential Bearing and Seal Kit is a complete rebuild solution for the Can-Am Maverick X3 Turbo, Turbo RR, and Max variants, Commander 1000R, and Defender 1000 and Defender Max 1000 platforms. The kit includes all bearings and seals needed to fully service the front differential — everything in one box, no separate sourcing required. Over time, front differential bearings wear down from heat, load, and contamination, leading to noise, vibration, and rough engagement. Seals degrade and begin to leak, allowing fluid loss and dirt ingress that accelerate the damage. Catching it early with a full bearing and seal replacement restores smooth, quiet operation and protects the differential gears from the kind of wear that leads to complete differential failure. Whether you're rebuilding after a leak, addressing a whine or grinding noise from the front end, or performing preventive maintenance on a high-mileage machine, this kit gives you everything needed for a thorough, professional-quality front differential service.
