Ball bearings should always be your first upgrades; that reduce
friction for less rolling resistance, and that means higher speed and
longer the running times. Ball bearings hardly require maintenance
and last a lot longer than stock Oilite bushings.
Our Yeah Racing Ball Bearings have the lowest resistance. They are manufactured perciously by Aircraft quality steel. Pre-lubricated with light protection oil, not any grease to
ensure its excellent performance!
