These products are great. fits fine. Even the old plastic items also good. they are not broken yet after 1 year use. front plastic drive shaft only broken.
Great product. Fast shipping. Thanks banggood.
comes perfect looks good thanks Banggood
great upgrade, factory ones were wearing out in the rear, goes great with the metal axle. a bit of work to install but worth it.
ok but expensive. cheaper to just buy flyhal fc5000
Everything fits when you know how to screw it up.
Fits perfectly to HBX 16889. Installed all metal upgrades as shown in pics and car runs smoothly.
Great fit and much stronger than the standard fit plastic units.
Great upgrade. Thanks banggood
Goods arrived today, I am satisfied thank you
