Aluminum Steering Upgrade for YZ-4S

RC racers seeking sharper handling can fit the Yokomo S4-200AA Aluminum Steering Bellcrank to their YZ-4S. This machined aluminum replacement swaps in for the stock resin bellcrank to add stiffness and a more direct steering feel.

Advantages of Aluminum in Steering

Aluminum reduces flex compared with resin, improving durability and translating small steering inputs into predictable wheel movement. The increased rigidity helps maintain consistent steering behavior under hard cornering and repeated impacts.

Model Fitment and Simple Installation

This steering bellcrank is compatible with the following Yokomo models: B-YZ4SF, B-YZ4SF2-1, MOR-010, and MOR-020. Installation is straightforward and can be completed with common RC tools, so you can return to track tuning quickly.
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.

How will the handling change after fitting the aluminum bellcrank?

Expect reduced compliance in the steering train with crisper turn in and steadier exit. The car will feel more direct under steering load.

Do I need special tools to install this part?

No special equipment is required; standard hex drivers and pliers used for RC maintenance are sufficient. Take care with threadlock where metal fasteners meet the chassis.

Will this work with my stock servo and linkages?

The bellcrank fits standard YZ-4S mounting points. Check linkage geometry and trim or adjust rod length if required to maintain correct steering throw.
