The Yokomo S4-415RS2A aluminium rear hub carrier is a straight swap that firms the rear end of the YZ-4SF2, reducing unwanted flex. This upgrade gives the car a more planted feel when pushing through corners and over bumps.
Built from quality aluminium, the carrier resists deformation better than stock plastic parts and stands up to frequent use. The reduced flex helps maintain more consistent geometry, which benefits lap time and driver confidence.
Specifically engineered for the YZ-4SF2 chassis, the component fits precisely and integrates with existing hardware. Installation is straightforward for hobbyists familiar with basic RC maintenance.
