TKO introduces a new special proprietary design 5x13x4 bearing for the Losi clutch. (Patent Pending)

The bearing has 2 seals. One Blue and one Black. The BLUE seal faces the front of the car.

These bearings have a higher RPM rating than standard 5x13s and are capable of withstanding high radial and axial loads for much improved performance and life.

These are the best clutch bearings available.
