Must Have When Upgrading Motor
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 used these when I replaced the brushed motor to brushless. Works perfectly.
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.

Not a quality material
Literally the first drive out with the upgraded inmetal parts and a new engine and M6 soon ran it into a curb. The first thing that broke is the new metal piece where the drive shaft sits. Surprised this before before other plastic pieces.

Sold as an upgrade but mine had them.
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.

Good quality upgrade
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

Perfect fit for my 18858.
Perfect fit for my 18858. Upgraded to brushless and the plastic gears would slip at full speed. Not a problem anymore!
