Race-Grade Slipper Component for YZ-4S

The Yokomo S4-303DCBA Slipper Drive Cup is intended for the YZ-4S series, concentrating on the bearing side to strengthen drivetrain durability. It helps deliver predictable power to the wheels and supports sustained performance during competitive runs. Perfect for hobbyists wanting a reliable replacement part.

Compatibility and Fit Notes

Compatible with several chassis designs, the S4-303DCBA fits models such as B-YZ4SF, B-YZ4SF2-1, MOR-010, and MOR-020. Accurate manufacturing tolerances help ensure correct installation and long service life.
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.

What tools do I need to fit the S4-303DCBA?

Standard RC hand tools are sufficient: hex drivers, pliers, and a small mallet if required. Work on a clean bench, and take care when seating the cup on the bearing side to avoid damaging seals.

Should I lubricate the mating surfaces?

A light application of appropriate grease on splines or mating surfaces can reduce wear and ease assembly. Wipe away excess and avoid contaminating friction surfaces that affect slipper performance.

Does this change require other upgrades?

Not necessarily. The S4-303DCBA is a direct replacement for the bearing-side cup. Inspect related drivetrain parts while you are servicing the car and only replace other items if they show wear.
