High Roller only sells the highest quality ceramic bearings for high bite foam tire dirt oval and pan car racing. These are ABEC-9 bearings with stainless steel races and Si3N4 ceramic balls. They come lightly oiled and ready to run out of the pack. We currently offer complete bearing kits for foam tire dirt oval cars like the 2022 GFRP direct drive sprint and latemodel, Custom Works G8 direct drive latemodel (or any CW car with the updated DD unit) and the Ghost latemodel amd sprint car. We also have flanged bearing kits for the new style BSR front wheels as well as non-flanged Custom Works and RC4Less wheels. We plan to expand with more kits and different sizes as we grow!
