TKO Radial/Thrust Clutch bearings
TKO Competition development have introduced a new radial / thrust design bearing (5x13x4) for use in the clutch of Losi 1/8th scale off roaders. The Patent Pending bearing has 2 seals, one blue and one black, with the blue seal facing 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 improved performance and life. Their 5×10 bearing has also been updated with these 2 different coloured seals.
