The YIKONG YK4072 DF7 Upgrade Parts Gearbox Housing itself does not require lubrication, as it serves as the protective housing for the gearbox. However, when installing it, it's recommended to apply a small amount of gear grease to the internal gears. This helps reduce friction and wear, ensuring smoother drivetrain operation for your YIKONG YK4072 DF7 RC Car. Avoid using excessive grease, as it can attract dirt and debris.
