A+

We used these to experiment with gearing ratios in a 1/10 scale rock crawler. All are nicely finished, no burrs or imperfections. Set screws thread in and work as they should. We used an adapter on the shaft to adjust the size, but may not be necessary depending on the shaft size of your motor - worked just fine with the adapter.We did lots of bashing and rock crawling with these - mesh well against the stock/OE metal gear - no issues, no stripping, no signs of wear. Excellent quality gears.

They have been holding up on 4s with no issues so far.

These are probably fine with plastic spur gears, but if you have a hardened spur then these will be too soft and they won’t last long at all

Nice set of pinions, makes adjustments easy and reliable. Works great so far.

These are cheaply made! After one run in Rustler 4x4 vxl they are chewed up. Yes I have a metal spur but my other pinions of a different brand have not problem.

Two runs, take off and return, and the gear was grinded with no teeth. Might be a better fit for other scale vehicles just not 1/8

Perfect in every way.
