Robinson Racing Motor Shaft Reducer Sleeves 1/8 Motor

This part will reduce an 1/8" (3.17mm) bore pinion gear down to fit on a 2mm motor shaft. This part was exactly what I needed and it fit nice and tight just like I had hoped. I've used Robinson Racing parts in other RCs and they've always been top notch quality so I knew I could rely on them for a part like this. Upgraded my kid's Yeti Jr to a Mamba Micro brushless setup and the motor came with a 2mm shaft. Stock yeti jr motor shaft is 2.3mm, so the stock pinion did not fit. Ordered this reducer sleeve along with a couple Robinson Racing 1/8" bore 48P pinions and everything fit perfect. Ended up dropping from a 15T to a 12T pinion for this setup, but I tried both and switching the sleeve over from one pinion to another was not an issue. The sleeve did not deform or get stuck on any part after being ran for a while.

You can always count on Robinson for quality parts
