We have all of the most important RC bearing sizes in stock and ready to ship. We also have bearing kits for our most popular cars. Bearing kits are a very good investment when you buy a new car since you will always have a spare bearing with you in case of bearing failure.

This means that the bearing has an:
Inner diameter of 5mm
Outer diameter of 10mm
Thickness of 4mm
