RC Car & Truck Ceramic Lightning bearing 4 packs are specially designed for on-road or relatively clean driving environments. These ABEC #1 bearings have stainless steel races, retainers and shields with ceramic balls. Ceramic hybrids are lighter, have less rolling resistance and can sustain higher operating temperatures than traditional bearings. All Ceramic Lightning bearings are packed in grease and will require a short break in period to loosen up. KIT
