Upgrade RSx 12 Servo Output with KO Propo 99103 5th Gear

The KO Propo 99103 5th Gear replaces the factory part to deliver stronger wear resistance and smoother gear engagement for RSx 12 servos. It is suited for hobbyists who service or tune their servos and want reliable operation under varied driving conditions.

Benefits of the KO Propo 5th Gear

Built to match the RSx 12 gear train, this component offers precise fitment and reduced backlash. The tougher construction helps prevent premature failure during sustained use, making it a solid choice for owners focused on durability.

Fitting Advice and Care

Before fitting the KO Propo 99103 5th Gear, clean the servo internals and check bearings and seals. Light lubrication on mating surfaces and correct mesh adjustment will extend service life and keep actuation smooth.

Remark :

Due to limited stock availability, please notice that some KO Propo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this gear work in older RSx 12 versions?

It is designed for the RSx 12 family, but variations in older batches can affect fit. Check part numbers and compare dimensions before installation.

How should I lubricate the new gear?

Use a light synthetic grease on the teeth and avoid over application. Reapply at regular service intervals if you notice noise or stiffness.
