The Yokomo S4-503D17A 16T Drive Gear provides dependable torque transfer for YZ-4S platforms. Engineered to mesh with the S4-503R17 ring gear, it keeps driveline action predictable whether you are running on rough terrain or smooth circuits.

Sturdy Build for Consistent Running

Produced with close tolerances, this 16T drive gear improves reliability under repeated stress. Its stable construction reduces slop and helps maintain handling balance when pushing the car hard.

Simple Fitment Across Yokomo Models

Fits Yokomo chassis such as B-YZ4SF, B-YZ4SF2-1, MOR-010, and MOR-020. Installation is user friendly, letting enthusiasts swap the part quickly during tune sessions.
Remark :
Due to limited stock availability, please notice that some Yokomo 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 change handling characteristics?

The gear itself keeps power delivery consistent; any handling change is more likely due to altered drivetrain lash or differing gear wear. Proper mesh prevents unwanted feedback.

Can it be used for both racing and practice?

Yes. The S4-503D17A is suitable for regular track use and practice sessions, offering a balance of durability and smooth engagement for repeated running.

How often should I inspect the gear?

Inspect teeth and mounting points after heavy sessions or if you notice noise or vibration. Regular checks help catch wear before it affects performance.
