RC Ball bearings should always be your first upgrades, it reduces friction for less rolling resistance, and that means higher speed and longer the running times. RC Ball bearings hardly require maintenance and last a lot longer than stock Oilite bushings.

Yeah Racing RC Ball Bearings have the lowest resistance. They are manufactured by Aircraft quality steel. Pre-lubricated to ensure its excellent performance!

These high quality bearings outweigh the other low quality one:

• Aircraft quality material
• More durable
• Higher precision

*Now comes with bearing oil for maintaining bearings in long run. (This new bearing set (with bearing oil) will replace the old item.)
