Stiffen Your YZ-4S with the Yokomo S4-003FCA Front Brace

The Yokomo S4-003FCA Graphite Front Chassis Brace is a practical upgrade for the YZ-4S platform that increases chassis rigidity. Manufactured from high-grade graphite and mounted over the resin chassis brace, it delivers greater durability and steadier behaviour during fast runs and rough track sections.

Why Graphite Works for Chassis Bracing

Graphite is prized for its high stiffness to weight ratio, so fitting this brace reduces unwanted flex while keeping overall mass low. The result is snappier steering response and improved on-track precision for YZ-4S setups tuned for speed.

Fitment and Installation Notes

This front brace fits a range of Yokomo parts including B-YZ4SF, B-YZ4SF2-1, MOR-010, and MOR-020. Installation is straightforward and requires only basic hand tools, allowing hobbyists to upgrade quickly and return to the track with minimal downtime.
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 hard is the S4-003FCA to fit on my YZ-4S?

Fitting the S4-003FCA is generally simple: remove the stock brace, position the graphite piece on the resin mount and secure with the existing screws. Most racers will take 10-20 minutes.

Will the graphite brace change handling significantly?

You should notice reduced front flex and a firmer turn-in. Changes are subtle but improve responsiveness, especially on high speed corners and bumpy sections.

Any maintenance tips for the graphite part?

Inspect mounting screws and the resin interface after a few runs. Tighten hardware to spec and check for any cracks around resin mounting points to keep performance consistent.
