Get more of that weight out front!! Please note: When using 5mm pinions smaller than 11 tooth the pinion gear is closed ended. You must space the motor back to allow for the longer pinion gear. Everything you need to run an 8, 9, or 10T pinion gear on your KRATOS, or ACIS SIX motors. Don't forget to add the blue loctite to all the screws!
Includes: 2-3mm motor mount screws
