Stiffen the Rear End of Your YZ-4SF2 with the Yokomo S4-415RS2A

The Yokomo S4-415RS2A aluminum rear hub carrier is a practical upgrade for the YZ-4SF2 that tightens up rear suspension flex. The added rigidity helps keep the car predictable during quick direction changes and high-speed sections.

Increased Chassis Control Through Stiffer Components

Machined from durable aluminum, this hub carrier is noticeably firmer than stock plastic pieces and resists wear from aggressive use. By limiting unwanted movement in the rear suspension, it supports cleaner cornering and steadier throttle response for racers and club drivers alike.

Fit and Simple Installation

Made specifically for the YZ-4SF2 chassis, the part drops into place with minimal fuss and uses standard hardware. Basic tools are all you need to swap in the S4-415RS2A and get back on the track 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.

What tools are needed to fit the S4-415RS2A?

A set of hex drivers and a small socket or nut driver are typically enough. You may also want thread locker for long term security if you run hard sessions.

Will this part change handling balance?

Yes, increasing rear stiffness usually tightens the rear end, reducing oversteer and making the car more stable on power, so you may want minor shock or toe tweaks after fitting.

Is the S4-415RS2A more durable than plastic hubs?

Aluminum offers better wear resistance and less flex under load, so it holds geometry longer during aggressive driving compared to standard plastic carriers.
