The 3Racing SAK-U418 rear shock tower is a 3.5mm graphite component aimed at improving rear stiffness on the Sakura Ultimate chassis. Its reinforced structure reduces unwanted flex and supports more predictable handling at speed.
Engineered for the Sakura Ultimate series, the SAK-U418 provides a stiffer mounting point without excessive mass. That improved rigidity can make suspension adjustments feel more immediate and easier to tune on different track surfaces.
The unit is produced to match Sakura Ultimate mounting geometry for a direct fit and easy installation. It is a sensible upgrade for anyone replacing a worn tower or seeking a firmer rear end for competition.
