Bones .410 Bearing Wheel Spacers 4pk

Many people forgo spacers as an unnecessary item (like truck washers)...I used to myself. But all of these components are designed to work in harmony with your bearings to help them spin efficiently while minimizing drag caused by the inner race rolling around the axle instead of staying stationary so the bearing can spin. Truck washers lock against the outer edge of the inner race. Bearing spacers connect the two inner races to one another.
