someone on rc crawler said they also had 2 spare bearings in the same kit so im not worried too much unless we bothed missed them but thats ulikeley. had many spare parts for this kit. mostly hardware and some shock o-rings, e clips, linkage components (things i couldnt have missed). hopefully gmade did include the bearings as a courtesy. the small size may suggest they are prone to failure so a couple spares were nice to include.
