Enhance Rear Predictability on the YZ-4SF2 with the Yokomo S4-415RS2A

The Yokomo S4-415RS2A aluminium rear hub carrier is a focused upgrade that reduces flex in the YZ-4SF2 rear suspension, producing steadier behaviour when cornering at speed. It suits drivers seeking more consistent handling feedback.

Stiffer Alloy Part for Controlled Handling

Forged from aluminium, this carrier offers a marked reduction in flex compared with OEM plastic items and is built to withstand frequent track use. The stiffer rear aids in maintaining setup geometry and improves mid corner stability.

Simple Fitment to the YZ-4SF2 Chassis

Engineered for the YZ-4SF2, the unit installs using existing mounting points and standard tools. The S4-415RS2A provides a hassle-free upgrade with immediate handling benefits.

Will fitting this part affect rear toe or camber?

The carrier itself preserves mounting geometry, but the reduced compliance can change effective toe and camber under load, so check alignment after installation.

Is any special maintenance required for aluminium parts?

Regular inspection for burrs or stripped threads is recommended; keep mating surfaces clean and reapply thread locker if you run in dusty or wet conditions.

Can this part be used for competition?

Yes, its increased rigidity and durability make it a common upgrade for competitive drivers seeking consistent rear behaviour, but always confirm class rules if racing in regulated events.
