HAIBOXING RC Cars Spare Parts Metal Spur Gear Drive Pinions and Diff Complete Apply to 18859A & 2021 New Version 18859 M1901 M1902

I installed these metal parts in connection with an upgrade to a brushless motor in my son's car (model 18858). This was an easy replacement of the plastic parts that came with the original car. I would recommend purchasing some grease as well and applying as part of the replacement. Overall, very happy with the parts.

I added a brushless motor and ESC to a brushed RC car. This was an essential part for the driveline to stay in one piece. Used the stock bearings and it was a direct replacement over the stock nylon gears and diff. Added a little greasr to the contact points and these allow the car to rip.

Made of very poor metal it's better if you look for alternative the gear does not last. 🫣😰😯🤬🤬🤬🫤😐

I purchased these metal parts because they were advertised as an upgrade for the haiboxing 16889A but when I opened mine, it already had them from factory. They're sturdy. Definitely need to upgrade to these if you have plastic ones. Great product and good prices.

It worked

Bought these to replace a blown diff in my sons HBX 18859 truck. Wasn't bad to install (assuming you have worked on rc cars before). Grease everything up when installing, I prefer white lithium, however any grease should work. Good upgrade parts

Extra parts are lovely to have

rear diff died completely after 2 weeks. yes it was greased.
