Team JB Hobbies presents the Armored Monkey Series bearing kits!

First came our Monkey Series, which were good all around chrome steel bearings.  But we wanted something tougher, so we gave them armor!  Our Armored Monkey Series features hybrid ceramic bearings offering 30% more toughness while reducing friction by up to 40% - giving you increased speed.

To top it off, we also produced these with nylon retainers which can handle up to 60% more speed than your competitors using standard steel.


This kit is compatible with the following models:

  • Arrma 3s BLX 100 3200kv
  • Arrma 4s BLX 120 2400kv
  • Looking for Arrma 6s? Check our our other listing and save!

This kit includes the following premium bearings:

  • 2 - 5x13x4mm
  • 1 - 5x16x5mm
  • Note - You will only use 2 bearings, we include 3 to cover both the newer and older versions of the motors.

Enjoy these features specifically designed with your motor in mind!

  • Ceramic Silicon Nitride Si3N4 balls
  • Nylon Retainers
  • Rubber Shields

Nylon retainers can handle up to 60% more speed than your standard steel retainer.
