Our Honda Grom wheel bearing kit includes the 4 wheel bearings necessary to replace every roller bearing in your wheels. Our bearings and utilize SI3N4 ceramic balls to minimize rolling resistance. These bearings have an extremely high resistance to heat and wear. All bearings are pre-lubed with low friction Mobil Polyrex EM grease prior to shipping.
Ceramic ball bearings are harder than steel balls and therefore have less rolling resistance and less overall wear. This means less rolling resistance and extended life from your bearings!
