The Factory Pro FP-O-DB3189 low friction driver belt is a key replacement part for keeping your 1/10 scale RC car running smoothly. The 63-tooth, 189mm profile fits common 1/10 drivetrains and is made to deliver consistent belt engagement.
Built for reduced friction and stable power transfer, this belt helps minimize drivetrain losses for both racing and club track sessions. It is suitable for hobbyists who want predictable throttle response and lower wear on pulleys.
Fit the belt with clean pulleys and check alignment before running. Regular inspections for glazing, fraying, or tooth wear will tell you when the FP-O-DB3189 needs replacing.
