These reducers allow you to run a more standard 5mm driveshaft like this with your stock UTB18 axles and/or transmission.

For install:

1. install the reducer sleeve over the trans output shaft or axle input shaft (keep in mind, you may need to reshim)
2. install one of the supplied pins
3. install the new driveshaft (will hold the pin in position), making sure the setscrew lines up with the flat on the reducer
4. tighten the driveshaft setscrew

Kit includes: 4 reducers, and 4 pins
