Bottom Line
This 91T Slipper Gear Set offers a solid, cost-effective way to upgrade or replace your Arrma Senton or Granite’s slipper gear with decent durability and improved performance over stock parts. However, the thin hub pin and bearing slop limit its appeal for long-term or hardcore racing use, so if you want truly rugged and precise components, you might want to look for alternatives with tighter tolerances and stronger hubs. For a budget-conscious buyer who needs a reliable upgrade now, this set will work fine but keep an eye on wear and consider pairing it with reinforced hubs.
