If you want to run regular 6374 motors or even larger ones, you want to use these spacers. Each spacer is 5mm long, ensure you have enough spacers for your setup (crossbars are 119mm long by themselves). Also use the 0.5mm washers that comes with the crossbar if needed for adjusting with 0.5mm increments, to nail that perfect in-line belt setup.
- Kit includes 12pcs 5mm aluminum spacers in same finish as crossbars.
- 4pcs M4 30mm.
- 4pcs M4 40mm.
